甜地丁脂溶性成分的GC-MS分析

目的:应用气相色谱-质谱法(GC-MS)分析甜地丁脂溶性化学成分.方法:采用石油醚提取甜地丁中的脂溶性成分,气相色谱-质谱联用技术对所得的脂溶性成分进行分析.结果:共鉴定出22个成分,占脂溶性成分总量的98.12％.其中含量较高成分为3-异辛氧基丙胺(23.178％),α-脱氢孤挺花宁碱(20.388％),2-甲氧基苯硫酚(11.387％),3-甲基十七烷(9.278％),(Z)-3-十六烯(7.000％).结论:甜地丁脂溶性成分中含烷、烯、酮、酚、醇、醛、酯类等多种化学成分,具有较高的医药、食品应用价值,分析结果为甜地丁资源的进一步开发利用提供了科学依据.

GC-MS Analysis of Liposoluble Constituents from Herba Gueldenstaedtiae Vernae

Objective:The liposoluble constituents from Herba Gueldenstaedtiae Vernae were analyzed by GC-MS.Method: The liposoluble constituents were extracted by solvents petroleum ether and further identified by GC-MS and their relative content was calculated by area normalization method.Result: Through comparison with mass spectra database,twenty-two components,which accounted for 98.12% of the peak areas,were separated and identified.The major components were 3-(2-ethylhexyloxy)-propylamine(23.178%),α-dihydrocaranine(20.388%),2-methoxy benzenethiol(11.387%),3-methylheptadecane(9.278%),(Z)-3-hexadecene(7.000%).Conclusion: The liposoluble constituents have high application value in medicine and food industry and mainly consisted of alkane,olefin,ketone,phenol,alcohol,aldehyde,ester,etc.The present experiments provided a scientific basis for the further exploitation and utilization of this herb.
