摘要

目的: 研究炮制前后黄精中化学成分的变化。方法: 制备不同炮制时间的酒黄精

顶空进样-气相色谱-质谱(GC-MS)联用技术进行分析

经数据库检索并参考正构烷烃标准品保留指数(RI)

确定化合物结构。应用色谱峰峰面积归一化法计算各成分的相对百分含量。结果: 生品与各炮制品共有的成分12个

但每种成分含量不同。与生品比较

炮制不同时间产生的成分20个

检测不到的成分7个。结论: 黄精炮制后化学成分组成和含量发生变化。

Abstract

Objective:To study the constituent changes of Polygonati Rhizoma before and after processing. Method: Polygonati Rhizoma was prepared with wine by stewing for different time. Headspace injection-GC-MS was used and the structures of compounds were identified by Data Base Retrieval and compared with the retention indexes of n-alkanes standards. The relative content of every constituent was obtained from the peak area normalization method of chromatographic peaks. Result: There are 12 common compounds between raw products and processed products

yet the relative content was different. Compared with raw products

20 compounds produced and 7 disappeared after different processed for different time. Conclusion: The chemical constituents and content have changed in the root of Polygonati Rhizoma before and after processing.
