GC-MS法分析两产地蛇床子中挥发油成分

目的:分析安徽和河南两产地蛇床子中挥发油成分。方法:采用水蒸气蒸馏法从蛇床子中提取挥发油,用气相色谱-质谱(GC-MS)法检测两产地蛇床子中挥发油成分,用面积归一化法计算其相对百分含量;用毛细管GC法分离并鉴定各峰对应的化合物。结果:安徽产蛇床子鉴定出36个成分,河南产蛇床子鉴定出45个成分,二者只有28个成分相同,差异较大。结论:本试验结果可为进一步开发利用蛇床子提供理论依据。

Analysis of the Essential Oil from Cnidium monnieri in Two Different Producing Areas by GC-MS

OBJECTIVE:To analyze the chemical components of the essential oil from Cnidium monnieri from Anhui versus Henan by GC-MS.METHODS:The essential oil was extracted from Cnidium monnieri by steam distillation;the chemical components of the essential oil were detected by GC-MS;the relative contents of the chemical components were computed using area normalization method.Peaks were separated by capillary GC-MS and their corresponding compounds were identified.RESULTS:36 chief components from Cnidium monnieri from Anhui and 45 from that from Henan were identified.28 components were noted in both.There was great difference between the two Cnidium monnieri.CONCLUSION:This study serves as a scientific basis for the further exploitation and utilization of Cnidium monnieri.
