广西产五月艾挥发油成分分析

目的:分析广西不同产地五月艾挥发油的主要化学成分,并与艾叶挥发油成分进行对比研究。方法:采用水蒸气蒸馏法分别提取艾叶和广西产五月艾中的挥发油,并通过气相色谱-质谱联用技术对其挥发油成分进行分析。结果:广西不同产地五月艾挥发油的得率为0.32%～0.67%,与艾叶比较均含有桉油精、樟脑、龙脑、大根香叶烯D、石竹烯、石竹烯氧化物、松油醇、薁类等特征成分。但不同产地五月艾的挥发油中同一成分的含量变化较大,而且组成挥发油的个别成分也有差异。结论:本研究结果可为合理应用广西产五月艾药材提供一定的科学依据。

Analysis of the Constituents of Volatile Oil in Artemisia Indica from Guangxi

OBJECTIVE： To analyze the constituents of volatile oil in Artemisia indica from different area of Guangxi, and to compared which with those in Artemisia argyi. METHODS： The volatile oil was extracted from Artemisia indica and Artemisia argyi respectively by steam distillation. The constituents of the volatile oil were identified by GC- MS technology. RESULTS： The yield of the collected volatile oil of Artemisia indica from different area of Guangxi was 0.32%--0.67%, and compared with Arternisia argyi, both were found to contain the following main constituents： eucalyptol, camphor, borneol, germacrene D, caryophyllene, caryophyllene oxide, terpineol, azulene etc. But the content of the same constituents in Artemisia indica varied with different producing area and there was also difference for a certain constituent of the volatile oil. CONCLUSION： The study results serve as a scientific basis for rational use of Artemisia indica from Guangxi.
