摘要:

采用超临界CO₂提取山石榴果实挥发油,并利用GC-MS联用技术分析挥发油的化学组成。从山石榴果实挥发油中分离、鉴定出33个化合物,占挥发油总量的89.43%。挥发油主要由各种酯、脂肪酸成分组成,含量较高的成分是11,14-二十碳二烯酸甲酯(11,14-eicosadienoic acid,methyl ester,42.49%),棕榈酸(palmitic acid,15.34%),硬脂酸(stearic acid,10.54%),肉豆蔻酸(myristic acid,6.26%),十六酸乙酯(hexadecanoic acid,ethyl ester,5.84%)。

Abstract:

The volatile oils were extracted from the fruits of Catunaregam spinosa by supercritical CO₂,analyzed by capillary GC-MS techniques,and the relative content of each component was determined by area normalization method. 33 components were isolated and identified from the volatile oils which account for 89.43% of total oil and were dominated by ester and carboxylic acid fractions. The main constituents were 11,14-eicosadienoic acid,methyl ester(42.49%),palmitic acid(15.34%),stearic acid(10.54%),myristic acid(6.26%),hexadecanoic acid,ethyl ester(5.84%)respectively.
