Abstract: The fatty acids of seed oil of microula sikkimensis Hemsl in Tianzhu Cunty of Gansu province were determined by using methods of GC/MS.11 Fatty acids which are about 99.92% of total seed oil have been identified.The main compounds are linoleic acid, oleic acid, a-Linolenoic acid,Gondoic acid, palmitic acid, γ-linoenoic acid, and stearic acid.Among 11 compounds there are 4 saturated fatty acids and 7 unsaturated fatty acids.The contents of them are 13.54% and 86.46% of total contents of 11 compounds respectively.Among them the conten of γ-linoenic is 6.37%.The seed oil content of Microula sikkimensis Hemsl is 43.5%.

Key words: Seed oil of Microula sikkimensis Hemsl, Fatty acid, γ-linolenoic acid, GC/MS
