板蓝根脂溶性成分的GC-MS分析

GC-MS Analysis of Liposoluble Constituents in Isatis indigotica

目的:分析、鉴定板蓝根的脂溶性成分。方法:采用石油醚萃取板蓝根的脂溶性成分,进行甲酯化处理后用气相色谱-质谱联用技术分离和鉴定其组成和含量。结果:从石油醚萃取部位共鉴定出42种脂溶性成分,其中脂肪酸甲酯化产物占36.72%(饱和脂肪酸甲酯为8.67%、不饱和脂肪酸甲酯为28.05%);有35种成分在板蓝根脂溶性成分的研究中未见报道。结论:板蓝根脂溶性成分可为其综合利用以及开发抗氧化方面应用提供参考。

OBJECTIVE： To analyze and identify the liposoluble constituents in Isatis indigotica .METHODS： The liposoluble constituents in Isatis indigotica were extracted with petroleum benzin,and the constituents in methyl ester products were sperated,identified and determined by GC/MS.RESULTS：A total of 42 liposoluble compounds were detected, with fatty acid methyl esters making up 36.72% （saturated fatty acid methyl esters 8.67% and unsaturated fatty acid methyl esters 28.05%）, and of which, 35 were reported for the first time in the study of Isatis indigotica .CONCLUSION： The liposoluble compounds in Isatis indigotica serve as reference for its comprehensive benefits and development of its antioxydant applilication.
