气相色谱/质谱法分析蕨麻中的脂肪酸成分

分别采用索氏抽提法和酸水解法提取蕨麻脂肪酸成分,再经过甲酯化处理后,通过气相色谱/质谱联用技术分析脂肪酸的组成。共检出20种脂肪酸成分,除了含有亚油酸、亚麻酸、油酸、棕榈酸、硬脂酸和邻苯二甲酸二异辛酯等主要成分外,还含有十一烷酸、十五烷酸、十七烷酸等奇数碳脂肪酸。索氏抽提法和酸水解法提取脂肪酸中多不饱和脂肪酸成分分别占71.1%和41.9%。

The Study on the Fatty Acid Compositions in Potentilla anserine L. by GC/MS

The fatty acid compositions in Potentilla anserine L.were extracted by Soxhler extractor and acid-hydrolysis method.After being methyl esterified,the fatty acid compositions were detected by GC/MS.There were 20 fatty acid were identified,besides some main components,as linoleic acid,linolenic acid,oleic acid,palmitic acid,and stearic acid,diisooctyl phthalate and some fatty acids of odd carbons,as undecanoic acid,pentadecanoic acid,heptadecanoic acid,were also found.The quantities of polyunsaturated fatty acid obtained by two methods were 71.1% and 41.9% respectively.
