竹枝细柄草花序挥发油成分的GC-MS分析

GC-MS Analysis of the Volatile Oil from Inflorescence of Capillipedium assimile (Steud.) A. Camus

摘要:

采用常压水蒸气蒸馏法提取竹枝细柄草(Capillipedium assimile (Steud.) A. Camus)花序的挥发油,经GC-MS分析,从花序挥发油中鉴定出45种化合物,占总油量的93.24%。其中含量较高的为4-十一烷酮(18.520%)、(E)-己酸-2-己烯酯(8.042%)、4-壬醇(7.778%)、4-十一醇(7.265%)、乙酸庚酯(6.787%)。

Abstract:

The volatile oils were extracted from inflorescences of Capillipedium assimile (Steud.) A. Camus by means of the steam distillation. Forty-five compounds were identified from the oils by GC-MS analysis, accounting for 93.24% of the total volatile oils. The main constituents were 4-undecanone (18.52%), (E)-2-hexenyl hexanoate (8.042%), 4-nonanol (7.778%), 4-undecanol (7.265%), and heptyl hexanoate (6.787%), etc.
