超声波辅助提取栀子油及其脂肪酸组成分析研究_杨冀艳 . Study on Ultrasound-assisted Extraction of Gardenia jasminoides Seed Oil and Its Analysis of Fatty Acid Composition

Abstract

In the present study,the oil was extracted from Gardenia jasminoides seeds by ultrasound-assisted extraction(28 kHz and 100 W) with petroleum oil as solvent.The results showed that the highest extraction efficiency,16.49% is obtain under the following extraction conditions:material and solvent ratio 1:10(g/ml),ultrasound treatment time 45 min and extraction times 3.In the continuous study,GC-MS analysis was used to determine the fatty acid composition of the Gardenia jasminoides seed oil.It was found that the main fatty acids in the oil are pentadecanoic acid,heptadecanoic acid,octadecanoic acid,11-eicosenoic acid,eicosanoic acid and docosanoic acid,and squalene is also found in the Gardenia jasminoides seed oil.The relative content of linoleic acid is the highest.
