国产姜黄属植物的化学成分分析

目的：为姜黄属中药材品种系统整理与质量标准规范化提供了参考依据。方法：采用比色法、薄层层析比色法及水蒸气蒸馏法，分别测定姜黄属不同种类不同产地不同部位不同时期共３４个样品的总姜黄素、姜黄素和挥发油。结果和结论：姜黄属不同种类植物的总姜黄素类和姜黄素含量差异悬殊，可达上百倍，挥发油含量差异可达６倍，同一种类的不同产地之间差异较小；并且不同种类的姜黄素含量与挥发油含量存在较明显的相关性。

Determination on Chemical Constitutents of Curcuma L. Produced in China

Objective: To provide some valuable information for the research on species systematization and quality standardization of Curcuma drugs.Methods: Colorimetry,TLCcolorimetry and water vapour distillation were used to determine the contents of curcuminoids,curcumin and essential oils of 34 samples of Curcuma produced in China. Results:and Conclusion: The contents of curcuminoids and curcumin are different upto an extent of over 100 times among the varieties of Curcuma,and those of essential oils to an extent of 6 times.But there is little difference in the samples of the same species from different producing areas.There is also an obvious correlativity between the contents of curcuminoids and essential oils in the varieties of curcuma.
