摘 要:本文研究了河北产北柴胡药材中挥发油的化学成分。利用水蒸气蒸馏法提取河北产北柴胡药材中的挥发油,利用GS-MS(气象色谱-质谱)法对挥发油的成分进行分析鉴定,并利用色谱峰面积归一化法计算各组分的相对百分含量及其相似度。结果表明,共鉴定出55种化合物,其中含量较高的成分有L-抗坏血酸-2,6-二棕榈酸酯(23.85%)、2,4-癸二烯醛(7.02%)、炔醇(9.55%)、顺,顺-9,12-十八碳二烯-1-醇(5.63%)等。河北产北柴胡中挥发油成分较多,但相对含量不高,为北柴胡的质量控制和进一步开发利用提供依据。

Abstract:This paper aimed to study the chemical constituents of volatile oil extracted from Bupleurumchinense cultivated in Hebei Province. The volatile oil was extracted from roots of Bupleurumchinense with steam distillation method, and the chemical constituents were analyzed and identified by gas chromatography-mass spectrometry(GS-MS). The relative content of each component was calculated by area normalization method. The results showed that sixty-eight compounds were identified, the major compounds of volatile oil were 2,6-dihexadecanoate(23.85%),2,4-Decadienal(7.02%), Falcarinol(9.55%),9,12-Octadecadien-1-ol, (Z,Z)(5.63%)and etc. There was more components of the volatile oil from Bupleurumchinense cultivated in Hebei Province, but the relative content was not high. It provided the basis for the quality control and the further development and utilization of Bupleurumchinense.

柴胡為常用大宗中药材,具有和解表里、疏肝、升阳的功效,主治感冒发热,寒热往来等症。伞形科植物柴胡Bupleurumchinense DC.或狭叶柴胡B. scorzonerifoliumWilld.的干燥根为正品柴胡[1]。现代研究表明柴胡根部的主要活性物质有柴胡皂苷、挥发油和多糖类物质[2],另外还含有黄酮类物质以及多种矿质元素[3]。柴胡的挥发油主要用于治疗感冒发热的症状,有显著的疗效[4]。现代研究发现柴胡挥发油还具有抗肿瘤、抗病毒、增强记忆的功效[5]。柴胡中的挥发油成分已经鉴定出上百种[6],但不同产地的柴胡中其挥发油成分和含量不尽相同。本试验利用GS-MS法对河北邯郸涉县栽培的北柴胡中所含挥发油进行了分析,并与其他产地的北柴胡中的挥发油的含量和成分进行了比较,从而为北柴胡的质量控制及临床用药提供参考。
