摘要
为了对枸杞子药材及其有关制剂的质量进行控制,本文对不同产地的枸杞子进行了比较分析,收集其色谱、质谱图。本文仅对其脂溶性成分进行分析,以石油醚提取后,进行气相色谱/质谱(GC/MS)分析,对比各药材的总离子流图,进行组分差异分析。实验结果认为其总离子流图有较大的共同点,可作为定性的依据;但亦存在不同之处,各组分的相对百分含量不尽相同,所含成分亦有区别;利用计算机谱库检索并核对有关资料,个别组分还利用对照品进行对照,共鉴定出33种化合物。
In order to control the quantity of Gouqizi and its preparation. The fat-soluble components of Gouqizi from different sources were analysed by GC/MS. Analysed and compared their total ion chromatograms (TIC) . The results show that the basic components are alkane. fat acid. the ester of fat acid and some stigmastenol. Their total ion chromatograms are similar, but there is a little different in the TIC and the relative percentage contents. Their similar components may be used in identification of Gouqizi. 33 components in gouqizi have been identified.
