气质联用色谱测定四个产地牡丹皮挥发油成分

Determination of volatile oil constituents of Moutan cortex from four habitats by GC-MS

为了分析比较陕西、安徽、河南、山东4个产地牡丹皮挥发油的化学成分,采用超临界CO2萃取法、气相色谱-质谱联用仪(GC-MS)对陕西、安徽、河南、山东4个产地的牡丹皮挥发油进行成分鉴定。结果表明,山东、安徽、河南、陕西牡丹皮挥发油的得油率分别是0.26%、0.25%、0.22%、0.27%,丹皮酚相对含量为91.51%、87.83%、53.92%、84.07%,共有的化学成分有丹皮酚、油酸等。

In order to analyze and compare the chemical constituents of volatile oil from Moutan cortex from four habitats in Shaanxi,Anhui,Henan and Shandong,the volatile oil from four habitats of Shaanxi,Anhui,Henan and Shandong is identified by using the method of supercritical CO2 extraction and gas chromatography-mass spectrometry(GC-MS).Results showed that the yield of volatile oil extracted from Shandong,Anhui,Henan and Shaanxi were 0.26%,0.25%,0.22%and 0.27%respectively,the relative content of paeonol were 91.51%,87.83%,53.92%,84.07%,and the chemical constituents of four habitats were paeonol,oleic acid and so on.
