运用GC-MS技术对2种淫羊藿挥发性成分的比较分析

目的运用GC-MS技术对柔毛淫羊藿与朝鲜淫羊藿挥发性成分进行比较分析。方法采用水蒸气蒸馏法提取柔毛淫羊藿和朝鲜淫羊藿挥发油,运用气相色谱-质谱联用技术,结合计算机检索对其挥发油进行分离鉴定。结果共鉴定出2种淫羊藿中76个挥发性成分,其中28个共有成分。结论柔毛淫羊藿与朝鲜淫羊藿挥发油在组分和含量上存在一定的差异,本研究为2种淫羊藿药材的鉴别及质量控制提供了重要依据。

Analysis of the essential oil from two varieties of epimediums by GC-MS

Objective To analyze the chemical components of the essential oil from Epimedium pubescens Maxim.and Epimedium koreanum Nakai. by GC-MS. Methods The essential oil was extracted from two epimediums by steam distillation, the chemical components of the essential oi1 were detected by GC-MS, peaks and their corresponding compounds were identified through database index. Results 76 chief components from two varieties of epimediums were identified, 24 components were noted in both. Conclusion There were some differences in composition and content between the two kinds of epimediums. A scientific basis for the further identification and quality control of the two different species of epimediums was offered in this paper.
