钮子茎中石油醚提取物成分的GC-MS分析

目的]为秦巴山区钮子茎的综合开发利用提供理论依据。方法]以石油醚为溶剂,采用超声法对秦巴山区野生的钮子茎粉末进行提取,得石油醚提取物,利用GC-MS分析对其成分进行分离、鉴定。结果]从钮子茎的石油醚提取物中分离、鉴定出49种化合物,主要有萜类、脂肪酸、烯醇、烯烃、酚类化合物,占脂溶性成分总量的95.15%。钮子茎的石油醚提取物中相对含量最高的组分是(-)-斯巴醇,为22.07%,其次为棕榈酸,含量为11.18%,再次是β-芹子烯,含量为9.20%,它们的结构中都含有不饱和双键,预示着钮子茎的石油醚提取物可能具有一定的生理活性。结论]钮子茎的石油醚提取物具有良好的应用开发价值。

GC-MS Analysis of the Composition of Petroleum Extraction from Stem of Panax Japonicus

Objective] The study was to provide the basis for the comprehensive development and utilization of the stem of Panax japonicus in Qinba Mountains.Method] With petroleum as solvent,the petroleum extraction from the powder of wild P.japonicus stem in Qinba Mountains extracted by ultrasonic,and its composition was separated and identified by GC-MS analysis.Result] 49 compounds were separated and identified in the petroleum extraction of the stem of P.japonicus,and the main compounds were terpenes,fatty acids,enolase,olefins and phenolic compounds,which shared 95.15% of the total liposoluble constituents.The compound with highest relatively content was spathulenol(22.07%),the second was palmitic acid with the content of 11.18% and the third was selinene with the content of 9.20%.Their construction all contained unsaturated double bonds,which indicated that the petroleum extraction from the wild P.japonicus stem could had some physiological activity.Conclusion] The petroleum extraction from the P.japonicus stem had good value on application and exploitation.
