舞草挥发性成分的气相色谱/质谱分析

Analysis of Codariocalyx motorius by gas chromatography-mass spectroscopy

摘要: 目的:分析舞草挥发油的化学成分。方法:采用微波萃取法从舞草中提取挥发油;用气相色谱-质谱法对其化学成分进行分离鉴定;用归一化法测定其相对含量。结果:分离出70个峰,其中鉴定了42种成分,占挥发油色谱峰面积的89.03%。结论:舞草挥发油的主要成分为1,3-二（3-苯氧基苯氧基）苯、植酮、棕榈酸、二十二烷等,百分含量依次为:37.70%、6.60%、21.61%、6.73%。

Abstract: Objective:To analyze the main chemical constituents of the essential oil from Codariocalyx motorius. Methods:The essential oil was extracted from Codariocalyx motorius by microwave extraction.The components of the essential oil were separated and identified by GC-MS.The relative content of each component was determined by area normalization.Results:70 peaks were separated and 42 of them were identified, representing about 89.03% of the total content. Conclusions:The main chemical constituents of the essential oil from Codariocalyx motorius were m-bis ( m-phenoxyphenoxy) benzene ( 37.70%) , fitone ( 6.60%) , Palmitic acid ( 21.61%) and n-docosane ( 6.73%) .
