As a tropical country with biodiversity, Indonesia is rich flora especially those potential as medicinal plants such Jarak Kepyar (Ricinus communis). Leaves of jarak kepyar communis) are used medicine for wounds, rash, abscess, and fever. Therefore, the purpose this study was to determine active compound in ethanol n-hexane extract leaves using phytochemical analysis GC-MS. The research method ...

Examination of brain myelin proteins by sodium dodecyl sulfate-gel electrophoresis followed by fluorography clearly showed that both proteolipid protein (PLP) and DM-20 were acylated 24 h after the intracerebral injection of 30-day-old rats with C3H]palmitic acid. The radioactivity associated with PLP remained after purification, re-electrophoresis, and fluorography. Most of the radioactivity a...

A detailed chemical kinetic reaction mechanism is developed for the five major components of soy biodiesel and rapeseed biodiesel fuels. These components, methyl stearate, methyl oleate, methyl linoleate, methyl linolenate, and methyl palmitate, are large methyl ester molecules, some with carbon-carbon double bonds, and kinetic mechanisms for them as a family of fuels have not previously been a...

The mechanism by which fatty acids stimulate the biosynthesis of phosphatidylcholine has been studied in cultured rat hepatocytes. Long chain fatty acids (1 mM) stimulated approximately 1.9-fold [methyl-3H] choline incorporation from phosphocholine into phosphatidylcholine by isolated hepatocytes. Oleate and palmitate (4 mM) enhanced phosphatidylcholine production by 3- and 2.2-fold, respective...

Objective(s): Oleate can be produced through de novo synthesis, which contributes to biological processes and signaling pathways. However, the role of this non-essential fatty acid in hepatic development remains unclear. The current study aimed to evaluate the influence of early oleate deficiency induced by the inhibitor of de novo oleate synthesis MF-438 on fetal rat ...

The self-metathesis of methyl oleate and methyl ricinoleate was carried out in the presence of ruthenium alkylidene catalysts 1-4 in [bmim] and [bdmim][X] type ionic liquids (RTILs) (X = PF(6) (-), BF(4) (-) and NTf(2) (-)) using the gas chromatographic technique. Best catalytic performance was obtained in [bdmim][X] type ionic liquids when compared with [bmim][X] type ionic liquids. Catalyst r...

Thin films of methyl oleate, oleic acid, and di-octadecenoyl phosphatidylcholine were reacted with a 2% solution of OsO(4) in water for 1 hr at 0 degrees . As controls, methyl 9,10-dihydroxystearate and 9,10-dihydroxystearic acid were reacted with OsO(4) in 0.25 N NaOH in methanol for 1 hr at room temperature. The reaction products were isolated, purified, and analyzed by thin-layer chromatogra...

This paper reports solubility and diffusivity data for soy and rapeseed methyl esters in polyethylene together with comparisons with methyl oleate and linoleate. These data showed that there is no significant difference in diffusivity and solubility between all these penetrants. Data were used to discuss the reliability of predictive models for diffusion and solubility of additive type molecule...

Two cobalt-carbonyl oxo processes were developed to prepare useful products in high yield from fatty derivatives. In one process, hydroformylation in the presence of MeOH at 120 C gives dimethyl acetal esters from either methyl oleate or oleic acid. In the other, a two-step process, hydroformylation (120 C) followed by hydrogenation (180 C) gives better yields of hydroxY methyl esters from both...
