Synthesis and Characterization of Phenyl Camellia oleifera Seed Oil Ester Plasticizing PVC

Plasticizers are essential additives in the processing of polyvinyl chloride(PVC),with phthalate plasticizers being widely used.However,these conventional plasticizers have been shown to be harmful to human health and environmentally unfriendly,necessitating the exploration of eco-friendly bio-based alternatives.In this study,Camellia oleifera seed oil,a specialty resource in China,was utilized as a raw material and reacted with 4,4′-Methylenebis(N,N-diglycidylaniline)(AG-80)to synthesize Phenyl Camellia seed Oil Ester(PCSOE).PCSOE was employed as a plasticizer to prepare modified PVC films with varying concentrations,with the conventional plasticizer dioctyl phthalate(DOP)serving as a control.Experimental results demonstrate that PSCOE-plasticized PVC films exhibit enhanced hydrophilicity,tensile strength,and thermal stability compared to DOP-modified PVC films.The contact angle of PSCOE-plasticized PVC films ranges from 66.26°to 78.48°,which is generally lower than the contact angle of DOP-modified PVC films at 78.40°,indicating improved hydrophilicity due to the modification with PCSOE.The tensile strength of PSCOE-plasticized PVC films ranges from 17.73 to 20.17 MPa,all surpassing the value of 16.41 MPa for DOP-modified PVC films.Moreover,the temperatures corresponding to 5%,10%,and 50%weight loss for PVC samples modified with PCSOE are higher than those for DOP.Hence,PCSOE presents a viable alternative to DOP as a plasticizer for PVC materials.

In order to identify the molecular markers that can be widely used in the breeding of Brassica napus L.varieties with high seed oil content under different genetic backgrounds,we developed a Kompetitive Allele Specific PCR(KASP)marker for seed oil content on the basis of the results from available studies.The verification in the F_(2) population showed that the marker was closely linked to the quantitative trait locus(QTL)for oil content on chromosome A05.The findings helped to breed the‘Fengyou’varieties with high seed oil content in the middle reaches of the Yangtze River.

New Process for Extracting Oil and Starch from Tea Seeds

A new process for extracting oil and starch from tea seed was introduced. The new process included one special link compared with all of the processes used now for tea seed oil and starch production. The link was static fermentation by which oil bodies and starch were separated naturally from tea seeds. By the process, tea seed oil and starch which were in conformity with government standards about edible oil and starch were successfully produced with 16% and 8% of production rate, respectively. The new process has many advantages, such as more simple equipments, lower production cost and whole natural products, etc..

Optimization of Oil Extraction Conditions from Watermelon Seeds by Response Surface Methodology

Response surface methodology was used to optimize the extraction conditions of oil from watermelon seeds. Based on single factor experiments, the material to liquid ratio, extraction time and extraction solvent exhibited the highest effects on oil extraction. The mathematical model was established according to the Box-Behnken central composite design. The optimal extraction conditions consisted of a material to liquid ratio of 1：16.3 （g/ml）, an extraction time of 45.4 min, and petroleum ether as the organic solvent. The predicted and actual yields of watermelon seed oil were 27.92% and 28.04%, respectively. The extracted oil was analyzed by GC-MS. The results revealed that watermelon seed oil contained several types of acids and esters ; the relative percentages of the components were determined by a normalization method. The main fatty acids included linoleic acid, palmitic acid, oleic acid, and stearic acid, which accounted for 91.24% of the total components.

Anti-lipid-oxidation effects and edible safety evaluation of the oil extracted by a supercritical CO_(2) process from coix seed fermented by Monascus purpureus

The physicochemical properties and composition of coix seed oil produced by Monascus purpureus fermentation and supercritical CO_(2)extraction were determined.Anti-lipid-oxidation and edible safety were evaluated using a cholesterol-fish oil model,acute oral toxicity assay,and genetic toxicity assay in vitro and in vivo,respectively.The results show that the extraction oil from fermented coix seed(FCS-O)had good physicochemical quality and abundant active components with physiological function.In particular,γ-tocotrienol,γ-oryzanol,coixenolide and oleic acid concentrations reached 72.83μg/g,745.96μg/g,9.65 mg/g and 316.58 mg/100 g DW,respectively.The FCS-O exhibited higher antioxidant capability in inhibiting lipid oxidation and peroxidation.Compared to the blank control,the concentrations of 7-ketocholestreol and peroxide only were 8.42μg/mL and 16.16 mmol/kg at 168 h of oxidation(P<0.01).In addition,the FCS-O has been confirmed to be a very safe edible oil,with no acute toxicity(LD50>10 g/kg bw,considered actually non-toxic)and no induced mutagenicity,cytotoxicity or genotoxicity.These results serve as a good safety reference for future application of the oil from fermented coix seed.The development and utilization of this kind of oil will be beneficial as a food,food ingredient,nutritional supplement,or natural food antioxidant to promote good health function.

Profiling the effects of microwave-assisted and soxhlet extraction techniques on the physicochemical attributes of Moringa oleifera seed oil and proteins

There is a constant search for biomaterials from natural products like plants for food and industrial applications.The work embodied in this report aimed at investigating the effects of microwave-assisted and soxhlet extraction(MAE and SE) techniques on the functional physicochemical quality characteristics of Moringa oleifera seed oil and proteins extracts. M. oleifera seeds were ground to fine powders and oil was extracted by microwave-assisted and soxhlet extraction techniques using petroleum ether. Quality attributes including yield percent, moisture content,iodine, saponification, specific gravity, viscosity, p H, thiobarbituric acid, acid and peroxide values were measured. Mineral and vitamin contents, chemical/functional groups, fatty acid(FA) composition, and reducing power of the oil were evaluated. Metabolomics of protein extracted from the defatted powders were analyzed by nuclear magnetic resonance(NMR). M. oleifera oil from MAE and SE methods had good yield(34.25 ± 0.0%,28.75 ± 0.0%), low moisture content(0.008 ± 0.0%, 0.011 ± 0.0%), non-drying and unsaturated, moderately saponified, less dense(0.91 ± 0.01, 0.92 ± 0.02 g m L^(-1)), had Newtonian flow, were weakly acidic, showed good content of FAs, recorded strong potential for long shelf-life, showed stability against oxidative rancidity and enzymatic hydrolysis, had very rich deposits of micro-and macro-nutrients as well as water-soluble and lipidsoluble vitamins, and functional groups in the oil were reflective of its content of long-and medium-chain triglycerides(LCT and MCT). Monounsaturated and saturated fatty acids(MUFA and SFA) were detected and the oil has excellent ferric ion reducing power. NMR metabolomic assay revealed the presence of nine essential amino acids(EAAs) in the protein extract. MAE technique is a feasible and acceptable alternative for high throughput extraction of M. oleifera oil with high yield and excellent quality attributes. The study revealed that MAE did not impart any remarkable advantage(s) on the physicochemical properties of M. oleifera seed oil and protein compared to SE technique.

Phosphorus Containing Rubber Seed oil as a Flame Retardant Plasticizer for Polyvinyl Chloride

The application of phthalate plasticizers has been restricted around the world due to their poor migration and potential harm to the human body.Hence,producing functional bio-based plasticizers via exploiting clean and reusable resources meets the satisfaction of current demands.In this study,flame-retardant rubber seed oil-based plasticize(FRP)was prepared via epoxidation reaction and ring opening addition reactions,which was used as a flame-resistant plasticizer for polyvinyl chloride to replace petroleum-based phthalate plasticizer.When DOP was replaced with FRP,the torque of PVC blends increased from 11.4 to 18.4 N⋅m,the LOI value increased from 24.3%for PVC-FRP-0%to 33.1%for PVC-FRP-20.The THR value diminished from 39 MJ/m^(2)(pertaining to PVC-FRC-0)to 22 MJ/m^(2)Tg increased from 23°C to 47°C,the weight loss of plasticized PVC blends significantly reduced from 22.6%to 2.8%in leaching tests.The study provided a new way to prepare flame retardant plasticizer using rubber seed oil as raw material.

Plasticizing Effect of Camellia oleifera Seed-Oil-Based Plasticizer on PVC Material Modification

In this study,as the plasticizer,Camellia oleifera seed-oil-based cyclohexyl ester(COSOCE)was prepared by the reaction of cyclohexene oxide and refined C.oleifera seed oil(RCOSO)obtained by acidification hydrolysis after saponification.In addition,the structure of the target product was confirmed by Fourier transform infrared(FTIR)spectroscopy,nuclear magnetic resonance(NMR)spectroscopy,and Raman spectroscopy.COSOCE was used as plasticizer-modified polyvinyl chloride(PVC)membranes.The structure of the COSOCE-modified PVC membranes were characterized by Raman spectroscopy and scanning electron microscopy(SEM).The properties of the COSOCE-modified PVC membrane were characterized by contact angle measurements,universal testing machine,thermogravimetric analysis(TGA),and differential scanning calorimetry(DSC).The results revealed that(1)The COSOCE-modified PVC membranes exhibit a good microscopic morphology.Combined with energy-dispersive X-ray spectroscopy(EDS)and contact angle measurement results,the COSOCE-modified PVC membranes are confirmed to be a hydrophilic material.(2)The modified PVC membrane with 60%COSOCE exhibited the best mechanical properties.The tensile strength reached 23.56±2.94 MPa.(3)COSOCE-modified PVC material exhibited better thermal stability,with a loss rate of less than 75%at the end of the first decomposition stage.Compared with that of the dioctyl-phthalate(DOP)-modified PVC membrane,the initial decomposition temperature of PVC was increased by 1.17°C–8.17°C,and the residual rate was increased by 0.67%–5.75%.The carbon–carbon double bond in the COSOCE molecular structure can remove the free radicals generated during the degradation of PVC material and slow down the decomposition rate of PVC.In addition,the double bond can be cross-linked partially with the PVC molecular chain containing the conjugated polyene structure,thereby increasing the movement resistance of the PVC molecular chain segment.Hence,COSOCE can replace DOP as a PVC plasticizer.

Improvement of (Eruca sativa Mill) yield, oil, chemical constituents and antioxidant activity utilizing a by-product of yeast production (CMS) with zinc and boron under salinity stress conditions

The impact of low-quality irrigation water on plant development has garnered significant attention from researchers. In light of this, two field experiments were conducted to evaluate the performance, yield, oil production and composition, as well as active constituents of Rocket(Eruca sativa Mill) cultivated in calcareous soil under saline water irrigation. Foliar sprays containing condensed molasses soluble(CMS), zinc(Zn), and boron(B) alone or in combination were used for irrigation. The data obtained from measuring various parameters of Rocket following foliar spraying with CMS, Zn, B or their combinations demonstrated that most treatments resulted in a significant increase in these parameters. The highest values for most measurements were observed when foliar application included all three components(CMS + Zn + B), resulting in a seed yield of 184.6 g/m2and an oil content of 675.3 kg/ha. Compared to the control group, the macronutrient content of N, P, K, Mg, and Ca increased by 34.4%, 56%, 42%, 45%, and 39% respectively in the seeds treated with these components.Furthermore, carbohydrates, proteins, phenolics flavonoids, and antioxidants showed increases of 24%, 34%,21%, 43%, and 28% respectively compared to the control group. Gas-liquid chromatography analysis identified ten components present in the seed oil characterized by higher unsaturated fatty acids ranging from 81.28% to92.28% and lower saturated fatty acids ranging from 6.72% to 8.21%. Therefore, foliar spray application including CMS, zinc, and boron can help alleviate salinity effects on Rocket plants grown under saline water irrigation conditions while improving growth, yield, oil production, and nutritional content such as total carbohydrates, proteins, and macronutrients levels.

Seed oil triglycerides, fatty acids and amino acids have been estimated throughout this study. The moisture and ash content were 3.70% ± 0.1% and 2.90% ± 0.2%, respectively. The saponification and iodine values were respectively 181.96 ± 0.4 mg KOH/g of oil and 104.86 ± 0.6 g of iodine/100 g of oil. Polyunsaturated fatty acid content (50.94%) was the most important. Triglyceride (LLO, 22.4%) was the major triglyceride. 9 essential amino acids and 9 non-essential amino acids were identified. Phenylalanine (11697.82 ± 0.00 mg/kg) was the most important essential amino acid. The content of 21 minerals was determined and the most important was potassium (9323.13 ± 0.01 mg/kg). Ca/P, Ca/Mg, Ca/Mg and Na/K ratios were 0.34;1.18;0.04 and 0.19 respectively. B. aegyptiaca seed oil is a source of multiple nutritional values and can be used by the population for multipurpose.

Functional evaluation for effective compositions in seed oil of Korean pine

The effect of seed oil of Korean pine (Pinus koraiensis) on the rats' blood-fat and its anti-ageing function was stud-ied for appraising the efficacy of the seed oil of Korean pine. Sixty experimental rats were randomly divided into 5 groups (half males and half females in each group) as normal control group, high fat diet control group, and three groups (Group 1 Group 2, Group 3) that were fed with feedstuff with the contents of the seed oil of 2.0g/(kgd-1), 4.0g/(kgd-1) and 8.0g/(kgd-1), respec-tively. The indexes such as superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and anti-oxidation capacity (AOC) were measured by Reagent Kit method. It was found that the seed oil of the Korean pine could reduce the content of triglyc-eride and improve SOD as well as GSH-PX activity in serum. These indexes of the rats in Group 2 fed with Korean pine seed oil of 4.0 g/(kgd-1) reached the significant level and those of rats in Group 3 fed with the seed oil of 8.0 g/(kgd-1) reached the extremely significant level. The results indicated the seed oil of Korean pine had function of regulating the level of blood-fat and anti-ageing.

Antagonistic MADS-box transcription factors SEEDSTICK and SEPALLATA3 form a transcriptional regulatory network that regulates seed oil accumulation

Transcriptional regulation is essential for balancing multiple metabolic pathways that influence oil accumulation in seeds.Thus far,the transcriptional regulatory mechanisms that govern seed oil accumulation remain largely unknown.Here,we identified the transcriptional regulatory network composed of MADS-box transcription factors SEEDSTICK(STK)and SEPALLATA3(SEP3),which bridges several key genes to regulate oil accumulation in seeds.We found that STK,highly expressed in the developing embryo,positively regulates seed oil accumulation in Arabidopsis(Arabidopsis thaliana).Furthermore,we discovered that SEP3 physically interacts with STK in vivo and in vitro.Seed oil content is increased by the SEP3 mutation,while it is decreased by SEP3 overexpression.The chromatin immunoprecipitation,electrophoretic mobility shift assay,and transient dual-luciferase reporter assays showed that STK positively regulates seed oil accumulation by directly repressing the expression of MYB5,SEP3,and SEED FATTY ACID REDUCER 4(SFAR4).Moreover,genetic and molecular analyses demonstrated that STK and SEP3 antagonistically regulate seed oil production and that SEP3 weakens the binding ability of STK to MYB5,SEP3,and SFAR4.Additionally,we demonstrated that TRANSPARENT TESTA 8(TT8)and ACYL-ACYL CARRIER PROTEIN DESATURASE 3(AAD3)are direct targets of MYB5 during seed oil accumulation in Arabidopsis.Together,our findings provide the transcriptional regulatory network antagonistically orchestrated by STK and SEP3,which fine tunes oil accumulation in seeds.

The study demonstrates that ultrasound is a reliable and great efficiencytool for the fast extraction of Korean pine seed oil.

Diversity in seed oil content and fatty acid composition in Acer species with potential as sources of nervonic acid

Nervonic acid(NA,cis-15-tetracosenoic acid)is a very long-chain monounsaturated fatty acid that has been shown to be a core component of nerve fibers and nerve cells.It can be used to treat and prevent many neurological diseases.At present,commercially available NA is mainly derived from Acer truncatum seeds,which contain about 5%e6%NA in their seed oil.The aim of this study were to identify and analyze NA-containing Acer species that could be used as NA resource plants.For this purpose,46 Acer species seeds were collected in China and in some or all of the seed oils from these species 15 fatty acids were detected,including linoleic acid,oleic acid(C18:1D9,C18:1D11),erucic acid,palmitic acid,NA,linolenic acid(C18:3D6,9,12,C18:3D9,12,15),eicosenoic acid(C20:1D11,C20:1D13),stearic acid,behenic acid,tetracosanoic acid,arachidic acid,and docosadienoic acid.Nervonic acid was detected in all samples,but the content was highly variable among species.NA content over 9%was detected in eleven species,of which Acer elegantulum had the highest levels(13.90%).The seed oil content,seed weight,and fatty acid profiles varied among species,but the comprehensive evaluation value(W)showed that A.coriaceifolium could be a new potential NA resources plant.The results also showed that NA was significantly negatively correlated with palmitic acid,oleic acid,and eicosenoic acid,but positively correlated with eicosadienoic acid,behenic acid,erucic acid,and tetracosanoic acid,which indicate the probable pathway for NA biosynthesis in Acer plants.This study has identified Acer species that may serve as NA resources and will help guide subsequent species breeding programs.

Sperm quality improvement after date seed oil in Vitro supplementation in spontaneous and induced oxidative stress

In vitro supplementation with date seed oil （DSO） can protect spermatozoa against hydrogen peroxide （HiO2）- mediated damage and can improve sperm function, possibly owing to antioxidant properties. We tested the antioxidant effects of DSO on human sperm motility, sperm viability, reacted acrosome and lipid peroxidation assessed in vitro after H202-mediated oxidative damage in spermatozoa. Sixteen patients （mean age： 35 years; range： 25-45 years） referred to the Histology-Embryology Laboratory of the Medicine Faculty of Sfax for semen analysis after 12-24 months of sexual intercourse without conception were selected. After spermiogram, sperm selection by twointerface discontinuous Sill Select gradient was performed, and selected spermatozoa were used in four experimental assays： control; incubation with 100um H2O2; incubation with 0.1% DSO; and co-incubation with 0.1% DSO and 100 um H2O2. Motility and viability were determined using World Health Organization criteria. Acrosome reaction and lipid peroxidation were assessed by staining with fluorescein isothiocyanate-Pisum sativum and spectrophotometric measurement of malondialdehyde, respectively. Results showed that incubation with H2O2 alone led to a significant increase in lipid peroxidation （57.83%, P 〈 0.05） associated with a significant decrease in sperm motility, sperm viability （after 30 min and 24 h） and percentage of reacted acrosome （P 〈 0.05）. Date seed oil im- proved sperm motility after 24 h of incubation （P 〈 0.05） and protected spermatozoa against the deleterious effects of H2O2 on motility, viability, acrosome reaction and lipid peroxidation. We conclude that supplementation with DSO may have a function in antioxidant protection against male infertility.

Fatty acid analysis in the seeds of 50 Paeonia ostii individuals from the same population

Tree peony seeds are rich in α-linolenic acid(ALA), and the peony seed oil is now being produced in China. Paeonia ostii is the most widely used tree peony species for oil extraction, which is commercially called Fengdan and treated as a single cultivar. Here, 50 P. ostii individuals from the same population in northern China were randomly selected for fatty acids(FAs) analysis. Thirteen FAs were isolated, and the most abundant five were palmitic acid(5.31–6.99%), stearic acid(1.22–2.76%), oleic acid(18.78–28.15%), linoleic acid(11.86–26.10%), and ALA(41.11–57.51%). There were significant individual differences of plants in FA quality and quantity and the linoleic acid content in Plant No. 48 even exceeded the scope of 1–99%. Further statistical analysis indicated that most of the individual FAs, saturated FAs, unsaturated FAs, and total FAs levels showed significant positive correlations to each other, whereas the seed yield per plant was independent and not correlated to the factors mentioned above. Ward’s hierarchical clustering results grouped the 50 plants into four clusters based on FA contents and seed yield, and the seven plants in Cluster IV were identified as good candidates for oil production. Our results confirmed that the individual differences did occur in P. ostii and Fengdan cannot be simply treated as one uniform cultivar. Also, these results may help simplify the selection of plants for oil peony breeding and accelerate the development of the oil peony industry.

Chinese Torreya grandis cv.Merrillii seed oil affects obesity through accumulation of sciadonic acid and altering the composition of gut microbiota

Torreya grandis cv.Merrillii(Taxace,Torreya)is mainly distributed across the hilly areas of subtropical China and is well known for its nutritional value.In this study,the ameliorative effects of T.grandis seed oil on lipid metabolism were investigated,and the underlying mechanism was explored from the perspective of gut microbiota.Mice experiments showed that the rate of body mass gain in the group where the mice were fed a high-fat diet(HFD)and supplemented with 550 mg/(kg·day)T.grandis seed oil(HFD+TO550 group)was 42.27%,while it was 62.25%in the HFD group.Compared with the HFD group,the liver and fat indices,total cholesterol,triglycerides,and low-density lipoprotein cholesterol were reduced in the oil-supplement groups.Moreover,the oil supplement significantly changed the fatty acid composition and alleviated pathological damage to the liver caused by the high-fat diet.Additionally,the distinct clustering of bacteria in the composition of gut microbiota was observed in the oil treatment group compared with that in the HFD group.T.grandis seed oil significantly increased the abundance of the beneficial bacteria and short-chain fatty acid producers,including Lactobacillus,Bifidobacterium,Faecalibaculum and Allobaculum.Our results suggest that the supplements of T.grandis seed oil could alleviate hyperlipidemia caused by HFD.These positive effects are considered to be related with sciadonic acid(SCA)and are partially mediated by alterations in gut microbiota composition and functionality.
