山茱萸肉和种子脂溶性成分的GC_MS分析_白成科 . Analysis of Fat-soluble Components in Cornus officinalis Flesh and Seeds by GC-MS

Abstract

The fat-soluble components in the flesh and seeds of Cornus officinalis were extracted by Soxlet extraction, and then esterified and analyzed by gas chromatography-mass spectrometry in the end. The contents of the fatty acids were determined by the normalization method. There are thirty-one and thirty fat-soluble components detected and identified in flesh and seeds of Cornus officinalis, amounting to 90.91% and 98.61% in the total amounts of extractable substances, respectively. The major fat-soluble components in flesh of Cornus officinalis are found to be fatty acids(61.46%) and hydrocarbons(22.03%), with the main fatty acids as 9-Octadecenoic acid (18.73%) and 9, 12-Octadecadienoic acid (27.23%). But the fatty acids in the Cornus officinalis seed are amounting to 97.84%, with the main components as 9-Octadecenoic acid (58.86%), Octadecanoic acid (21.00%), hexadecanoic acid(7.10%), and 9,12-Octadecadienoic acid (4.08%). All non-fatty acid components are under 1%.
