Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample

3. Summarize an article from a peer reviewed journal dealing with one of the topics presented in the article. The article reviewed discussed the topic of human cytotoxicity in response to exposure to glyphosate‚ its major metabolite (AMPA)‚ and the commonly added surfactant compounds found in major herbicides. Glyphosate exposure has increased world-wide at an exponential rate along with the production of genetically modified crops. Currently up to 75% of genetically modified crops are treated

Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.

ABSTRACT Purpose: To evaluate the antifungal and cytotoxicity activity of four medicinal plants like Mystroxylon aethiopicum‚ Lonchocarpus capassa‚ Albizia anthelmentica and Myrica salicifolia. Methods: Microdilution method and brine shrimp lethality test were employed to evaluate antifungal and cytotoxicity of plant extracts. Results: Lonchocarpus capassa leaf extracts exhibited antifungal activity against tested fungal strains with MIC range of 0.78 – 3.125 mg/mL with LCLA extract inhibiting C
