白车轴草不同花期挥发性成分研究

Study on Volatile Components from Trifolium repens L.at Different Florescence

以白车轴草为原料,提取其花蕾、盛花和衰花中的精油,应用GC/MS/DS技术对其挥发性成分进行分析。结果表明,从花蕾精油中检出并鉴定39种物质(主要成分为烷、醇、酸、醚),其相对峰面积为82.25%;从盛花精油中检出并鉴定52种物质(主要成分为醇、烷、醚),其相对峰面积为68.23%;从衰花精油中检出并鉴定44种物质(主要成分为醇、醛),其相对峰面积为69.72%。

With Trifolium repens L. as the material, the essential oils was extracted from its bud, full and downfall flowers, and the volatile components in it were analyzed with GC/MS/DS. The results showed that there were 39 kinds of substance were detected out and identified in essential oils from bud （main components were alkane, alcohol, acid, ether） with relative peak area of 82.25%. There were 52 kinds of substance were detected out and identified in essential oils from full flowers （main components were alcohol, alkane, ether） with relative peak area of 68.23%. There were 44 kinds of substance were detected out and identified in essential oils from downfall flowers （ main components were alcohol and aldehyde） with relative peak area of 69.72%.
