不同种源迷迭香(Rosmarinus officinalis)种子萌发特性比较研究

在实验室条件下对6个种源迷迭香种子进行重量、形状及萌发特性的比较研究。迷迭香种子近椭圆形,长宽比为1.74～1.98,种子百粒重在0.12～0.18 g之间。其中,欧洲种源种子重量显著高于美洲种源种子(P<0.05)。萌发环境因子试验中,光照、温度和不同种源地对种子的发芽势和发芽率影响差异显著(P<0.05),15℃和光照条件下迷迭香种子有最高的发芽率;源于法国的种子发芽率为82%,显著高于其他种源地的种子发芽率(P<0.05),源于美国的种子发芽率最低,仅有27%;来自法国的种子平均发芽时间最长,为11 d,来自美国的平均发芽时间最短,为3 d。不同种源间发芽势与发芽率的变化趋势相同,发芽率与平均发芽时间呈负相关性,发芽率与种源地花期降雨量呈负相关性。迷迭香种子存在生理后熟或休眠机制,花期温度和降雨是影响不同种源种子萌发能力差异的主要原因,可将6个种源种子其分为欧洲和北美洲两大类,其形态学和生理指标表现出较强的地域性。

太空诱变对迷迭香(Rosmarinus officinalis L.)形态参数、光合能力和次生代谢产物含量和成分的影响

以未经太空诱变的迷迭香(Rosmarinus officinalis L.)为对照,研究了经返回式卫星搭载进行太空诱变后迷迭香在形态参数、光合作用以及次生产物代谢方面的变化。结果显示:太空诱变后,迷迭香优良株系的株高、冠幅、分枝数、分枝长、地上部生物量等形态参数有了明显提高,特别是反映迷迭香可采收量的地上部生物量,比诱变前提高了1.24倍。进一步研究发现,光合能力的提升是迷迭香诱变株系形态参数发生变化的一个重要原因,因为迷迭香诱变株系的叶绿素含量、最大净光合速率、表观量子效率比对照明显提高,而光补偿点则明显下降。作为迷迭香中最主要的生物活性物质,鼠尾草酸、迷迭香酸和精油的含量在太空诱变株系中明显高于对照,并且精油中主要组分的比例也发生了显著变化。上述结果表明,太空诱变中迷迭香可获得生物产量和经济产量的有益突变,从而证明航天育种技术在迷迭香优良品种选育中是可行的。

Chemical composition of Rosmarinus officinalis essential oil and antioxidant action against gastric damage induced by absolute ethanol in the rat

Objective: To evaluate the antioxidant activity of the essential oil obtained from Rosmarinus officinalis(R. officinalis) in ethanol-induced gastric ulcer model in vivo.Methods: The antioxidant properties of the essential oil obtained from R. officinalis were evaluated against gastric injury induced by absolute ethanol. Gastric tissues were prepared to enzymatic assays. The levels of glutathione, lipid peroxides, and the activities of glutathione peroxidase, superoxide dismutase and myeloperoxidase were measured.Results: Ethanol produced severe hemorrhagic lesions in the stomach with ulcerative lesion of(140.2 ± 37.2) mm2. In animals pretreated with essential oil of R. officinalis(50 mg/kg, p.o.), a significant inhibition of mucosal injury of(21.2 ± 7.1) mm2(84%inhibition) was observed. The essential oil of R. officinalis protected the gastric mucosa probably by modulating the activities of the enzymes(superoxide dismutase and glutathione peroxidase) and increasing or maintaining the levels of glutathione. In addition,lipid peroxides levels were reduced. The essential oil of R. officinalis was analyzed by gas chromatography–mass spectrometer and the main constituents were cineole(28.5%),camphor(27.7%) and alpha-pinene(21.3%).Conclusions: We suggest that the monoterpenes present in the essential oil obtained from R. officinalis may be among the active principles responsible for the antioxidant activity shown by essential oil of R. officinalis.

Essential oil of <i>Thymus vulgaris</i>L. and <i>Rosmarinus officinalis</i>L.: Gas chromatography-mass spectrometry analysis, cytotoxicity and antioxidant properties and antibacterial activities against foodborne pathogens

The essential oil composition of Thymus vulgaris L. and Rosmarinus officinalis L. endemic to France were determined by GC and GC-MS. Oils were assessed for their cytotoxic, antioxidant and antimicrobial activity. 31 and 37 different compounds were identified representing 99.64% and 99.38% of the thyme and rosemary oils respectively, where oxygenated monoterpenes constituted the main chemical class. Thymol (41.33%) and 1.8-cineole (24.10%) were identified as the main constituents of T. vulgaris L. and R. officinalis L., respectively. Essential oils (EOs) of selected plant species were evaluated for their in vitro cytotoxicity against the human lung adenocarcinoma epithelial cell line (A549). Cytotoxicity was measured using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphynyltetra-zolium bromide] colorimetric assay. Dose-dependent studies revealed IC50 of 8.50 ± 0.01 μg/mL and 10.50 ± 0.01 μg/mL after 72 h on the A549 cells for R. officinalis L. and T. vulgaris L., respectively. Antioxidant activity was determined using a quantitative DPPH (1,1-diphenyl- 2-picryl hydrazyl) assay. Thymus and rosemary EOs exhibited effective radical scavenging capacity with 50% inhibitory concentration (IC50) of 437 ± 5.46 μg/mL and 189 ± 2.38 μg/mL respectively and therefore acts as a natural antioxidant agent. The antimicrobial activity of these species has also been studied against several foodborne pathogens and food isolated Salmonella spp. including S. enteritidis of significant importance. According to the results, T. vulgaris L. showed higher bactericidal effect than those from R. officinalis L. These results suggest that the essential oil from T. vulgaris L. and R. officinalis L. have potential to be used as a natural cytotoxic, antioxidant and antimicrobial agent in food processing.

Isotherm, Kinetic and Thermodynamic Studies for the Sorption of Mercury (II) onto Activated Carbon from <i>Rosmarinus officinalis</i>Leaves

The present work deals with the equilibrium adsorption of Hg(II) onto carbonized Rosmarinus officinalis leaves (ACROL) as a new adsorbent from aqueous solution and it has been investigated. ACROL samples were prepared by physical carbonization at 773 K for 1 h. Titration method was used to determine the concentration of Hg(II) before and after adsorption onto ACROL by ethylenediaminetetraacetic acid, EDTA, as chelating agent. Batch equilibrium studies were carried out under different experimental conditions such as Hg(II) concentration and temperature. The relationship between the amount of Hg(II) onto ACROL can be described using four tow-parameter isotherm models. The equilibrium sorption data were analyzed using Freundlich, Langmuir, Dubinin-Radushkevich (DRK) and Temkin isotherms. The experimental results were found to fit the Langmuir isotherm model with a monolayer adsorption capacity of 588.2 mg/g at 318 K, while they were found to fit the Freundlich isotherm model at 298 K. The KL was decreased with increasing temperature, indicating a bond strength between Hg(II) and ACROL decreased with increasing temperature and sorption is exothermic. From DRK isotherm, free energy, E, was higher than 31 kJ/mol suggesting the Hg(II) adsorption onto ACROL chemical sorption. The thermodynamic studies revealed that the process is spontaneous nature of Hg(II) adsorption by ACROL and exothermic. The findings from this research show that ACROL has capability to remove Hg(II) from aqueous solutions.

Kinetic Study of the Oxidative Degradation of Choiba Oil(Dipteryx oleifera Benth.)with Addition of Rosemary Extract(Rosmarinus officinalis L.)

Choibá (Dipteryx oleifera Benth.) is a promising source of edible oil with high nutritional quality and a significant content of oleic acid (52% - 54%). To promote Choibá as source of edible oil is necessary to ensure its stability along the time of production, distribution and storage. Loss of nutritional and organoleptic quality in lipids is mainly due to lipid peroxidation reactions. The aim of this research was to evaluate the oxidative stability of Choibá oil at 100°C ± 1°C with aeration (1150 mL air/min) supplemented with rosemary extract (Rosmarinus officinalis L.), at 1000 mg/L (RE1000) and 1500 mg/L (RE1500), and with BHT (200 mg/L) and from this results to evaluate the degradation kinetics and shelf-life of Choibá oil at 35°C, 45°C and 55°C without addition of antioxidants (Control) and with addition of best concentration of rosemary extract obtained from previous study. Progress in oil oxidation was measured through the extent of oxidation products: peroxide value (PV) and thiobarbituric acid reactive substances (TBARS). Results revealed that the addition of rosemary extract at 1500 mg/L significantly reduced de formation of hydroperoxides (PV), more than BHT. Through correlations between concentrations of antioxidant (including control without antioxidant) with peroxide values, the kinetics of degradation and shelf-life of Choibá oil with predictive models are evaluated in real time and accelerated (35°C, 45°C and 55°C) using the Arrhenius equation. In addition, the oxidation reactions of this oil follow a first order kinetic model for PV and zero order kinetic model for TBARS. The rate of formation of PV was dependent on the storage temperature, according to the Arrhenius equation with the activation energy of 4611.5071 J/mol for Control and 7409.5771 J/mol for RE1500 treatment. The result of TBARS didn’t adjust to Arrhenius model, thus measurement of malondialdehyde (MDA) wasn’t a useful parameter for shelf-life determination of Choibá oil.

Stability Study of O/W Cosmetic Emulsions Using <i>Rosmarinus officinalis</i>and <i>Calendula officinalis</i>Extracts

Cosmetic emulsions, as all macro emulsions, are inherently unstable systems, from a thermodynamic viewpoint. More specific eco-friendly oil/water (O/W) cosmetic emulsions are usually less stable than conventional ones as milder chemicals or less intense (energy consuming) production processes are involved. In this context, two traditional techniques an optical technique and a volumetric one have been used for the assessment of the stability of cosmetic emulsions and compared to each other. Eco-friendly cosmetic emulsions were produced with different olive oil/water extracts (Rosmarinus officinalis and Calendula officinalis extracts) and emulsifier (Glycerol monostearate, GMS) concentrations. Emulsions’ stability was registered simultaneously by 1) Microscopy photos of samples withdrawn at regular intervals from the test vessel;2) global volumetric measurements of the different phases (water/oil/emulsion) inside the test vessel made at regular intervals for determining the evolution of the location of the phases separation interface. Analysis of the results of each technique and comparisons among them are presented and discussed in detail.

The Effect of N-Fertilization on Rosmarinus Officinalis L. （An Upright Variety） Yield in Central Greece

The effect of three different N-fertilization levels （NI： 625, N2：385 and N3：770 kg hal; where in case of N1 was used the 3-6-10＋3MGO＋30% OM and in cases of N2-N3 the 26-0-0 fertilizers） on fresh and dry weight of the perennial Rosmarinus officinalis （upright cultivar） was investigated during the 2nd year after establishment at the Experimental Farm of the Technological Educational Institute of Thessaly in Greece （TEI; Larissa plain） in 2015. It is well documented that the crop reaches its potential yield on the third year of cultivation and continues producing biomass for as long as eight years. Complete weather data （air temperature, radiation, air humidity, precipitation） were recorded hourly in an automatic meteorological station, which was installed to the experimental farm of TEI. Upon harvest （November 3rd 2015）, the crop reached a maximum fresh yield of 11.67 tons per hectare and dry yield of 4.3, respectively. The average fresh weight was 8.2, 8.4 and 8.9 t hal and the dry weight were 2.6, 3.1 and 3.2 t ha-1 for the N1, N2 and N3 levels, respectively. Furthermore the higher moisture content was observed in the case of N1 level （68%）. Therefore, the above data show that rosemary cultivation could be a promising alternative crop, especially in case of the consideration that average selling price of dry rosemary in Greece is 3.5 ∈ kg^-1 and the average gross income exceeds the amount of 10,000 ∈ ha^-1.

Antibacterial,antioxidative and sensory properties of Ziziphora clinopodioides–Rosmarinus officinalis essential oil nanoencapsulated using sodium alginate in raw lamb burger patties

This study was aimed to encapsulate Ziziphora clinopodioides –Rosmarinus officinalis essential oil (Z-REO) using sodium alginate (NaAlg) and to evaluate its performance on antimicrobial and antioxidative activities and sensory attributes in lamb burger patties during cold storage for 12 days.GC-MS analysis of Z-REO indicated carvacrol (21.5%) and thymol (16.9%) were the major components.SEM images showed the formation of encapsulated particles.The presence of encapsulated Z-REO in NaAlg was proved based on the increase in band intensity of FTIR spectra.By increasing mass ratios of NaAlg:Z-REO from 1:1 to 2:1,and 4:1,encapsulation efficiency was increased.Average zeta-potential values (mV) of the mass ratios 4:1 and 2:1 were −48.67 and −44.83,indicating the stability of encapsulated particles.The average size of particles ranged from 159.14 nm to 256.14 nm.The results showed that the encapsulated nanoparticles could markedly decrease the growth of inoculated Escherichia coli O157:H7 and Staphylococcus aureus and delay the lipid oxidation of lamb patties compared to the control samples and in samples with free Z-REO.Furthermore,nanoparticles efficiently decreased discoloration and off-odor development in the patties.Therefore,NaAlg-Z-REO nanoparticles could efficiently reduce bacterial growth and oxidative or sensory deterioration of lamb patties during storage.

Adsorption properties of Rosmarinus officinalis oil as green corrosion inhibitors on C38 steel in 0.5 M H_2SO_4

Rosmarinus officinalis essential oil obtained by hydrodistillation was tested as corrosion inhibitor of steel in 0.5 M H2SO4 using weight loss measurements, and electrochemical .polarisation methods. Results obtained indicate that the corrosion rate is reduced and R. officinalis oil adsorbs on the metal surface and then inhibits corrosion process. Its inhibition efficiency increases with oil increasing content to reach 61% at 1 g/L. Polarisation curves indicate that RO acts as a cathodic inhibitor. The inhibition efficiency of naturally oil remains slightly constant with the rise of temperature. Chemical analysis of R. officinalis essential oil was carried out using capillary GC and GC/MS. The oil composition was characterized by high amount of oxygenated monoterpene （77%） with 1,8-cineol （52.1%） as main component. Discussion of adsorption was investigated on the the isotherm adsorption of essential oil on basis of essential oil composition. Finally the steel has been also reported.
