贵州产昆明山海棠茎叶中化学成分研究

目的研究贵州产昆明山海棠茎叶中主要有效成分含量，分析其入药的可能性。方法：采用薄层层析法和分光光度法分析不同部位样品中化学成分。结果：实验表明枝叶中含量很少，不可入药；但是直径大于0．5cm的茎中含量尚可，其中生物碱含量达0．03％（RSD＜1．58％，n=5）；总萜内酯含量达0．036％（RSD＜2．55％，n=5）；雷公藤内酯醇含量达0．016％（RSD＜1．24％，n=5）。结论：直径大于0．5cm的茎完全可以作为根的代用品。

Study on the Chemical Components in the Stems and Leaves of T.Hypoglaucum Levi. Hutch Growing in Guizhou

AIM:To assay the contents of active components in the stems and leaves of T.Hypoglaucum Levl.Hutch Growing inGuizhou. METHODS:TLC and spectrophotometry were used for qualitative and quantitative analysis respectively. RESULTS: Theexperiment showed that the contents of active components in the leaves and fine branches were so low that they could not be usedas medicine.The contents in thick stems(diameter＞0.5cm) were as follows: alkaloid 0.03%(RSD＜1.58%,n=5);total terpenoids 0.036%(RSD＜1.24%,n=5);triptolide 0.016%(RSD＜1.24%,n=5).CONCLUSION:The thick stems can be used for replacement of the roots.
