GC-FID analysis of fatty acids and biological activity of Zanthoxylum rhetsa (Roxb.) DC seed oil

The Fatty acid content and composition of fixed oil from Zanthoxylum rhetsa seeds was determined. The seeds were found to contain about ～19.5% of crude fixed oil on a dry weight basis. Fatty acids were converted into methyl esters and analyzed by GC-FID. Ten fatty acids were identified using GC-FID. The major monounsaturated and saturated fatty acids were oleic acid (41.6 - 43.5%) and palmitic acid (26.8-30.2%) respectively, whereas the α-linolenic acid (12.1 - 12.5%) and linoleic acid (10.0%) were polyunsaturated fatty acid. Stearic acid (5.2 - 6.0%), myristic acid (0.1%), traces of pentadecanoic, heptadecanoic and arachidic acid were also identified. These fatty acids have not been reported earlier from the oil of Z. rhetsa. Fixed oil exhibited significant free radical scavenging activity which was measured using DPPH, and is also known to inhibit the gastrointestinal motility significantly.

SYNTHESIS OF PHEROMONES, IV. CHEMISTRY OF THE WITTIG REACTION, I. EFFECTS OF REACTION CONDITIONS ON THE STEREOSELECTIVITY AND YIELD OF THE WITTIG REACTION

The reactions of nonstabilized triphenylphosphorus ylides with aldehydes have been studied in detail.The stereochemistry and yields of the alkene products are highly dependent upon base used for the generation of the ylide, the solvent and reaction temperature.The synthesis of sex pheromone components by Wittig reaction are also described.

A NOVEL STEREOCONTROLLED SYNTHESIS OF (Z,Z)-3,13-OCTADECDIEN-1-YL ACETATE, THE SEX PHEROMONE OF SYNANTHEDON SPECIES

Starting from 10-undecenoic acid, a stereocontrolled synthesis of (Z,Z)-3,13-octadecadien-1-yl acetate with high sterochemical purity was achieved by the use of Wittig-olefinations for the introductions of (Z)-double bonds.
