Isolation and Identification of Fatty Acid Component from Seed Oil of Microula sikkimensis (Clarke) Hemsl

Li Jing-min, Wang Jing-ping and Yu Peng-lan   

Abstract: The seed oil content of Microula sikkimensis (Clarke) Hemsl. is up to 45% There is 8.1% of γ-linolenic acid which has the pharmacological action in the fatty acids composition, It has showed that this oil has a stronger effect on reducing triglyceride in serum. Fifteen different kinds of fatty acids were analysed. The unsaturated C20, C22, C24 acid, C18 triene-acid and tetraene-acid of the seed oil were separated on AgNO3-silica gel column and HPLC. and were identified by Periodata-Permanganate Oxidation, GLC, IR, UV, and MS. They are cis-11-eicosenoic, cis-13-docosenoic, cis-15-tetracosenoic, cis-6,9,12-octadecatrienoic and cis-6,9,12,15- octadecatetraenoic acids.

Key words: Seed oil, Microula sikkimensis. γ-linolenic acid, Fatty acid.
