The Phlomis bracteosa oil constituents of methyl ester derivatives of fatty acids were analyzed using Gas Chromatography coupled to mass spectrometer. The results obtained containing the saturated as well as unsaturated fatty acids of P. bracteosa oils. A total of 18 different components were identified and quantified. Methyl ester of octadecadienoic acid was found in high concentration 6.88 %,...

The immune system is one of the most important things that need to be preserved in midst Corona Virus Disease 2019 (Covid-19) pandemic. Consuming components compounds contained Madeira vine (Binahong) leaf oil right and regular doses can way enhance system. This obtained by carrying out extraction process with reflux method on leaf. study aimed determine optimal time temperature process. was ca...

In an examination ofthe volatile metabolic products of the odoriferous fungus Lentinuoa lepideu Fr., Birkinshaw & Findlay (1940) identified the methyl esters of p-methoxycinnamic, and cinnamic acids. Another acid, anisic acid, was also present as an ester but the nature of the alcohol moiety was left undetermined, although it was considered that the ester was probably the methyl ester. Another ...

Biodiesel is produced from vegetable oils (edible & non edibles) and animal fats. The methyl ester of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine and they would not require significant modification of existing engine hardware. At present, biodiesel is commercially produ...

Beta very low density lipoproteins (beta-VLDL) from cholesterol-fed animals from patients with Type III hyperlipoproteinemia are internalized by a receptor-mediated process in mouse macrophages. Once internalized, the cholesteryl esters of beta-VLDL are hydrolyzed in lysosomes, and the released cholesterol is re-esterified, resulting in a massive accumulation of cholesteryl esters. In the prese...

The purpose of this study was to identify bioactive compounds Beauveria bassiana entomopathogenic fungi derived from insect isolates Leptocorisa oratorius and endophytic B. cocoa plants that have bioactivity as growth boosters. research conducted in the laboratory Biological Control, Faculty Agriculture, Andalas University. for 4 months, using GCMS method. From results study, identified booster...

There is growing interest in biodiesel (fatty acid methyl ester or FAME) because of the similarity in its properties when compared to those of diesel fuels. Diesel engines operated on biodiesel have lower emissions of carbon monoxide, unburned hydrocarbons, particulate matter, and air toxics than when operated on petroleum-based diesel fuel. Production of fatty acid methyl ester (FAME) from rap...

A new volatile derivative of taurine, N-isobutoxycarbonyltaurine methyl ester (methyl 2-(N-isobutoxycarbonylamino)ethanesulfonate), was prepared by a three-step procedure for the gas chromatographic determination of taurine in urine. First, taurine was converted to its silver salt by reaction with silver oxide; next the silver salt was reacted with isobutyl chloroformate to form the N-isobutoxy...
