The cotyledons of jojoba (Simmondsia chinensis) seeds contained 50 to 60% of their weight as intracellular wax esters. During germination there was a gradual decrease in the wax content with a concomitant rise in soluble carbohydrates, suggesting that the wax played the role of a food reserve. Thin layer chromatography revealed that both the fatty alcohol and fatty acid were metabolized. The di...

The jojoba (Simmondsia chinensis) plant produces esters of long-chain alcohols and fatty acids (waxes) as a seed lipid energy reserve. This is in contrast to the triglycerides found in seeds of other plants. We purified an alcohol-forming fatty acyl-coenzyme A reductase (FAR) from developing embryos and cloned the cDNA encoding the enzyme. Expression of a cDNA in Escherichia coli confers FAR ac...

In this study, the fuel characteristics of biodiesel produced from jojoba [Simmondsia chinensis (Link) Schneider] oil and obtained procured under laboratory conditions were compared. For purpose, seed endosperm oil, which was attained calli via soxhlet extraction, obtained. Biodiesel transesterification method. It determined that biodiesels seeds close to each other, it observed other features ...

The corrosion inhibition reaction of plant distillates and their synergistic combination effect was studied. Atlas cedarwood distillate (ACW), admixture sage Jojoba (SJA), jojoba lavender (JLD) were evaluated at minimal concentrations to for on mild steel in 1 M H 2 SO 4 solution. Results showed ACW reacted poorly 1% 2% inhibitor concentration. However, from 3% - 6% concentration the final rate...

A cyclohexanecarboxamide derivative, N-phenyl-N-[1-(piperidine-1-carbonyl)cyclohexyl] benzamide (MNRC-5), was evaluated for its inhibitory effects on Schistosoma mansoni cercarial serine protease activity and cercarial penetration. MNRC-5 exerted an inhibitory effect on S. mansoni cercarial serine protease at serial concentrations of the specific chromogenic substrate Boc-Val-Leu-Gly-Arg-PNA fo...

The present work comprises the formulation and evaluation delivery system of transdermal drug with a view of developing and preparing a losartan potassium releasing system utilizing natural oils as permeation enhancers for transdermal applications. Matrix systems were prepared by using polyvinyl pyrrolidine and ethyl cellulose (EC) polymers by incorporating dibutyl phthalate as plasticizer and ...

the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...
