民族药鸭嘴花药用部分挥发油的GC-MS分析

GC-MS analysis of volatile oil from the medicinal part of Adhatoda vasica Nees

摘要:

采用水蒸气蒸馏法提取制备鸭嘴花中挥发油。并通过GC-MS和检索所用质谱库（NIST08.L，Wiley 275.L）检索研究其化学成分组成，用面积归一化法确定各成分的相对百分含量。从鸭嘴花药用部分挥发油中分离出202个色谱峰，鉴定了其中的51个化合物，占挥发油总量的47.83%。结果表明鸭嘴花药用部分挥发油中化合物种类丰富。对鸭嘴花挥发油化学成分的研究为该民族药药理活性提供了物质基础。

Abstract:

The volatile oil from the medicinal part of Adhatoda vasica Nees was separately prepared by steam distillation methods. The chemical components were analyzed by GC-MS and mass spectral library (NIST08.L, Wiley 275.L) with the area normali-zation method to determine the relative percentage content of each component. 202 peaks were found in the total ion chromatography graph with 51 compounds identified which accounted for 47.83% of the total essential oil. This result showed that there were abundant types of chemical constituents in the volatile oil from the medicinal part of Adhatoda vasica Nees. Investigation of the chemical constituents of Adhatoda vasica Nees may provide some references for the study of its biological activity material base.
