摘要
目的:分析比较不同提取方法制备的当归中的挥发性成分。方法:分别采用水蒸气蒸馏法和顶空加热提取当归挥发性成分,以气质联用技术分析其主要成分结构。结果:两种提取方法无论是成分种类还是其相对含量均存在很大的差异,水蒸气蒸馏法提取的挥发油经气质联用分析,可鉴定出43种挥发性化学成分;采用顶空进样经气质联用分析,鉴定出43种挥发性化学成分;二者共有成分为24种。结论:综合运用这两种方法可以建立较为全面的当归挥发性成分GC-MS表征体系。
Objective：To compare the difference of volatile components in Radix Angelicae Sinensis extracted with different methods. Methods：Volatile components in Radix Angelicae Sinensis were extracted by steam distillation（SD） and headspace injection（HS） respectively and analyzed by gas chromatography-mass spec- trometry（GC-MS）. Results：There was significant difference between the component type and its relative con- tent extracted by two methods,43 volatile chemical compounds were identified in volatile oil obtained by SD;whereas 43 volatile compounds were identified in the herb treated with HS. Total 24 common com- pounds were obtained from the volatile compounds extracted by two methods. Conclusion：The two methods combined with GC-MS can establish GC-MS representation system of the volatile compounds of Radix An- ~elicae Sinensis.
