摘要
以宽叶羌活为试材,采用水蒸气蒸馏法、GC-MS、主成分分析法及聚类分析法,研究了不同产地羌活挥发油含量和成分,以期为宽叶羌活挥发油研究提供一定的参考。结果表明:11批样品分5类,第一主成分为绒盖乡家种羌活与热加乡野生羌活,二者累积贡献率达72.84%,不同产地羌活挥发油的主要成分种类比较接近,4种共有成分为α-蒎烯、β-蒎烯、萜品烯、萜品油烯,主要成分为α-蒎烯、β-蒎烯、萜品烯。
The content and composition of Notopterygium franchetii H.de Boiss.in different origins were studied by steam distillation,GC-MS,component analysis and cluster analysis,in order to provide some references for the study of Notopterygium franchetii H.de Boiss.The results showed that 11 batches of samples were divided into 5categories.The first principal component was the native and wild species of Notopterygium franchetii,with the cumulative contribution rate of 72.84%.The main components of Notopterygium franchetii H.de Boiss.from different habitats were similar.Four common components(alpha-pinene,beta-pinene,terpene,terpene olefin)were found.The main constituents were alpha-pinene,beta-pinene,terpene.
