截叶铁扫帚提取物的GC-MS分析及羽扇烯酮的定性定量分析

GC-MS analysis of extractives from Lespedeza cuneate and qualitative and quantitative analysis of lupenone

摘要:

采用乙醇超声提取三个不同月份的截叶铁扫帚，并运用GCMS法分析截叶铁扫帚乙醚供试液的化学成分和羽扇烯酮的相对含量.结果显示从截叶铁扫帚中共检测出61种成分，5月份截叶铁扫帚的成分有42种，8月份有39种，11月份有42种，均主要为烷烃、萜类、芳香类物质，并首次发现截叶铁扫帚中含有羽扇烯酮，测得5月、8月、11月截叶铁扫帚中羽扇烯酮的含量分别为1.734mg/g、2.235mg/g、1.111mg/g.通过比较三个不同月份截叶铁扫帚中的化学成分及其含量，8月份截叶铁扫帚中化学成分种类最少，但羽扇烯酮含量最高.

Abstract:

Components of the Lespedeza cuneate from three different months were extracted by ultrasonic alcohol extraction method, the extractives were dissolved by ether and analyzed by GCMS, and quantitative analysis of lupenone by GCMS. Results showed that 61 components have been detected. Lespedeza cuneate included 42 components in May, 39 components in August and 42 components in November. The mainly include alkane, terpenoid and aromatics. The lupenone was firstly found in Lespedeza cuneate, and the relative contents of lupenone in May, August and November were respectively 1.734mg/g, 2.235mg/g and 1.111mg/g. Through comparison the Lespedeza cuneate constituents and contents of the three different months, the Lespedeza cuneate constituents was the least in August, but the contents of it is the highest.
