In vitro effects of Salvia officinalis L.essential oil on Candida albicans

Objective:To determine the anticandidal activities of Salvia officinalis L.(S.officinalis)essential oil against Candida albicans(C.albicans)and the inhibitory effects on the adhesion of C.albicans to polymethyl methacrylate(PMMA)resin surface.Methods:Disc diffusion method was first used to test the anticandidal activities of the S.officinalis L.essential oil against the reference strain(ATCC 90028)and 2 clinical strains of C.albicans.Then the minimal inhibitory concentration(MIC)and minimal lethal concentration(MLX)were determined by modified membrane method.The adhesion of C.albicans to PMMA resin surface was assessed after immersion with S.officinalis L.essential oil at various concentrations of 1XMIC.0.5XMIC and 0.25XMIC at room temperature for30 min.One-way ANOVA was used to compare the Candida cell adhesion with the pretreatment agents and Tukey's test was used for multiple comparisons.Results:5.officinalis L.essential oil exhibited anticandidal activity against all strains of C.albicans with inhibition zone ranging from 40.5 mm to 19.5 mm.The MIC and MLC of the oil were determined as 2.780 g/L against all test strains.According to the effects on C.albicans adhesion to PMMA resin surface,it was found that immersion in the essential oil at concentrations of 1XMIC(2.780 g/L).0.5XMIC(1.390 g/L)and0.25XMIC(0.695 g/L)for 30 min significantly reduced the adhesion of all 3 test strains to PMMA resin surface in a dose dependent manner(P<0.05).Conclusions:S.officinalis L.essential oil exhibited anticandidal activities against C.albicans and had inhibitory effects on the adhesion of the cells to PMMA resin surface.With further testing and development,S.officinalis essential oil may be used as an antifungal denture cleanser to prevent candidal adhesion and thus reduce the risk of candida-associated denture stomatitis.

Characterization and Bioaccessibility of Minerals in Seeds of Salvia hispanica L.

Salvia hispanica L. is a herbacia plant that originates from Mexico and Guatemala, and it is currently known by the popular name of chia. Currently, chia seeds have been considered to be of great importance for human health and nutrition because they have a high concentration of polyunsaturated fatty acids. They contain the largest known percentage of fatty α-linolenic acid (ALA) in plants—approximately 68%. Furthermore, they are an excellent source of protein, dietary fiber, calcium, magnesium, iron, vitamin B and phenolic compounds that have antioxidant properties. However, despite the high nutritional value present in the food and the possible health benefits of its nutrients, there is a need to evaluate the bioaccessibility of its micronutrients to measure their effectiveness. Thus, we evaluated the chemical composition of chia seeds from different producers, their lipid profiles and the bioaccessibility of some of their minerals.

Hepatoprotective and Antioxidant Effects of <i>Salvia officinalis</i>L. Hydroalcoholic Extract in Male Rats

The antioxidant effects of Salvia officinalis L. hydroalcoholic extract and also its hepatoprotective effects in male rats were evaluated. Salvia officinalis L. extract was administered intraperitoneally for 28 days. Serum levels of aspartate aminotransferase, alanine transferase and alkaline phosphates in rats coadministered with both isoniazid (INH) 50 mg/kg and Salvia officinalis L. extract at 250 mg/kg showed significant reduction when compared to INH group, but administration of Salvia officinalis L. extract 250 mg/kg alone and with INH has alleviated gamma-glutamyl transferase comparing to INH receiving rats. After treatment of rats with INH 50mg/kg, severe tissue necrosis, and inflammation of central vein in liver and lymphocyte proliferation were observed;in the experimental group receiving Salvia officinalis L. extract (250 mg/kg) mild dilution in central vein and sinusoids in liver were seen. In rats coadministered with Salvia officinalis L. extract 250 mg/kg and INH low sinusoids dilution was indicated. It seems that Salvia officinalis L. extract exhibited anti-oxidative and hepatoprotective effects.

Physical, Total Phenolic and Total Flavonoid Properties of Chia (Salvia hispanica L.) Seeds Grown in Kenya

In the recent past, there has been an increased uptake of chia seeds (Salvia hispanica L.) by consumers resulting in the increased adoption of chia farming, particularly in Kenya whereby most farmers are practising subsistence farming and a few farming it commercially. The widespread farming of chia seeds in Kenya translates to increased uptake at household level while offering a niche for industrial processing of chia seeds necessitating the need for studies on physical, total phenolic and flavonoid properties of chia seeds grown in Kenya. The physical, total phenolic and flavonoid properties of chia seeds from two chia planning seasons April to August 2019 and September to December 2019 were evaluated. The physical attributes (length, width and thickness) were determined using a digital vernier calliper while proximate components were determined using AOAC standard methods. The Quencher procedure was used to determine the total phenolic and flavonoid contents. Chia seeds revealed a length of 1.82 to 2.32 (mm), a width of 1.15 to 1.31 (mm) and a thickness of 0.77 to 0.88 (mm). The percentage moisture content of chia seeds was 7.23 to 10.67, percentage of crude fat was 31.48 to 42.45, percentage of crude ash was 3.63 to 6.82, and percentage of crude fibre was 30.95 to 38.65 and percentage of crude protein was17.82 to 28.97. The total phenolic content observed for chia seeds was 0.73 to 0.87 mg GAE g-1 while total flavonoid content was 0.39 to 0.57 mg GAE g-1. The proximate components of chia seeds varied significantly (p < 0.05) based on the chia planting season while the physical properties, total phenolics and total flavonoid contents did not vary significantly.

Analysis of Genotoxicity Induced by Food Dyes in Root Meristem of Salvia hispanica L.

Food dyes are chemicals either natural or synthetic that were used by humans to give attractive colors to numerous food products. Colorful food products may cause several health-related issues to us because they may be prepared through synthetic food dyes. The color which is intended to attract people to eat is given to them by the use of some artificial food dyes such as Erythrosine, Allura red, Indigostine, Tartrazine, Sunset yellow, etc. These artificial food dyes are synthetic chemicals that can cause numerous health-related problems if they were taken in by individuals more than the limited amount. Artificial food dyes are becoming very common in use in different ways to provide an attractive and soothing color to food products such as sweets, drinks, candies, etc. The food products we consume with very good and attractive colors are not as good for our health as they appear. Here in this study, we are observing the cytological effect of two different synthetic food dyes (Brilliant blue and Sunset yellow) in the root meristem of Salvia hispanica L. (Chia plant) which is a major source of α-linolenic acid, mainly omega 3 fatty acids and dietary fibers found in the seed. For this purpose, germinated seeds of Chia are in the germinator. After the emergence of the young roots, we have given the treatment of the respective dyes of 0.5%, 1%, 1.5% & 2% respectively with a control set. After treatment, the roots were fixed in Carnoy’s fixative and preserved in alcohol for further analysis. When the slides of the treated roots were prepared and analyzed we observed that numerous cytological abnormalities such as (stickiness, fragmentation, bridge, laggards, disorientation, etc.) were there in the root cells and the level of abnormalities are increasing with increasing treatment period due to the exposure of them to respective dyes. These results are enough to conclude that the consumption of these dyes is harmful to the health of humans.

Molecular mechanism of Salvia miltiorrhiza Bunge and Carthamus tinctorius L. in the treatment of myocardial ischemia based on network pharmacology: a comparative study

Based on network pharmacology and molecular docking technology,the similarities and differences of anti-myocardial ischemia mechanism between Salvia miltiorrhiza Bunge(SM)and Carthamus tinctorius L.(CT)were studied.Firstly,based on the traditional Chinese medicine systems pharmacology(TCMSP),the related compounds of SM and CT were obtained,and the potential targets of these compounds were collected by the target fishing method.Genecards database was used to obtain targets related to myocardial ischemia.The cross targets of CT,SM,and myocardial ischemia were then selected,and the protein-protein interaction(PPI)network was constructed based on the STRING database.The cross targets were imported into the Metascape database for Gene Oncology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis.Cytoscape software was used to build the topological network diagram of the drug-compound-target path.Finally,the binding ability of the active ingredient and the key target was verified by molecular docking.65 active ingredients and 38 potential targets were screened from SM,and 22 active ingredients and 58 potential targets were excavated from CT.Important targets common to SM and CT were TNF,IL6,VEGFA,AKT1,etc.The common enrichment pathways involved are fluid shear stress and atherosclerosis,IL-17 signaling pathway,pathways in cancer,and toxoplasmosis.The findings suggested that the two traditional Chinese medicines exerted the effect of myocardial ischemia through the characteristics of multiple targets,multiple pathways,and multiple compounds.

Rheum palmatum L. and Salvia miltiorrhiza Bge. Alleviates Acute Pancreatitis by Regulating Th17 Cell Differentiation: An Integrated Network Pharmacology Analysis, Molecular Dynamics Simulation and Experimental Validation

Objective: To identify the core targets of Rheum palmatum L. and Salvia miltiorrhiza Bge.,(Dahuang-Danshen, DH-DS) and the mechanism underlying its therapeutic efficacy in acute pancreatitis(AP)using a network pharmacology approach and validate the findings in animal experiments. Methods: Network pharmacology analysis was used to elucidate the mechanisms underlying the therapeutic effects of DH-DS in AP. The reliability of the results was verified by molecular docking simulation and molecular dynamics simulation.Finally, the results of network pharmacology enrichment analysis were verified by immunohistochemistry,Western blot analysis and real-time quantitative PCR, respectively. Results: Sixty-seven common targets of DH-DS in AP were identified and mitogen-activated protein kinase 3(MAPK3), Janus kinase 2(JAK2), signal transducer and activator of transcription 3(STAT3), protein c-Fos(FOS) were identified as core targets in the protein interaction(PPI) network analysis. Gene ontology analysis showed that cellular response to organic substance was the main functions of DH-DS in AP, and Kyoto Encyclopedia of Genes and Genomes analysis showed that the main pathway included Th17 cell differentiation. Molecular docking simulation confirmed that DH-DS binds with strong affinity to MAPK3, STAT3 and FOS. Molecular dynamics simulation revealed that FOS-isotanshinone Ⅱ and STAT3-dan-shexinkum d had good binding capacity. Animal experiments indicated that compared with the AP model group, DH-DS treatment effectively alleviated AP by inhibiting the expression of interleukin-1β, interleukin-6 and tumor necrosis factor-α, and blocking the activation of Th17 cell differentiation(P<0.01). Conclusion: DH-DS could inhibit the expression of inflammatory factors and protect pancreatic tissues,which would be functioned by regulating Th17 cell differentiation-related m RNA and protein expressions.

朱唇种子吸水特性及其在干旱胁迫下萌发特性

种子粘液质是植物在长期适应环境过程中形成的,该物质对于种子的扩散、定居、生存力的改善、萌发、幼苗生存乃至抵御有毒化学物质毒害等都具有重要的生态学意义。朱唇为唇形科鼠尾草属多年生草本植物,原产美洲热带地区,现已广泛栽植于世界各地。为了理解朱唇种子表面的粘液物质吸水特性和种子在干旱胁迫下的萌发特性,该研究以朱唇种子为材料,运用光学显微镜和扫描电子显微镜观察以及种子萌发试验的方法,对种子和粘液层的形态结构、粘液质对种子萌发的影响进行了研究。结果表明:朱唇种子为卵形,表面为负网状结构,千粒重为(1.611±0.0084)g,无粘液种子吸水倍数为3,粘液种子吸水倍数为25,粘液层吸水倍数为122。粘液和无粘液种子及粘液层的重量都随吸水时间的延长而增长,但脱水过程要远长于吸水过程。朱唇种子吸水2 h达到饱和,经过36 h可干燥失水恢复原重。不同浓度PEG对朱唇种子的萌发均有影响,发芽势随PEG浓度升高而显著降低。朱唇种子在5%PEG胁迫下发芽率最高达(90.00±8.66)%,20%PEG胁迫下发芽率最低为(76.67±10.41)%,低浓度PEG对朱唇种子萌发有一定促进作用。这说明朱唇种子为速萌型种子,其粘液质在种子吸水过程中起到举足轻重的作用,能保证短时间内有充足的水分供其萌发。
