滇芒果果仁脂肪酸组成分析—杜萍(GC-MS) . Analysis of Fatty Acid Composition of the Seed Kernel of Mango from Yunnan

Abstract

The seed kernel of mango from Yunnan was subjected to Soxhlet extraction, and the crude fat extraction efficiency was 14.23%. Then the extract was extracted with petroleum ether, saponified, and methyl esterfied and the esterfication products were applied to GC-MS for the analysis of fatty acid composition. Totally 13 fatty acid compounds were separated and their mass fractions were determined by the area normalization method. Most of the compounds were straight-chain fatty acids and the major components were stearic acid, palmitate acid, eicosanoic acid, heptadecanoic acid and docosanoic acid.
