五味子类生药的薄层光密度法鉴别研究

Studies on the Identification of Schisardra by TLC-Densitometry

用薄层光密度法对10种五味子中的木脂素进行了定性定量分析,绪果表明,10种五味子所含成分不同;同种五味子成分的含量因产地不同而异,10种五味子的薄层扫描图有显著差异。

This paper deals with the determination of the lignins in 10 species of Schisandra crude drugs by TLC-densitometry. The result shows that all the 10 species are unidentieal in the lignin constituents; the same species vary in the contents with habitats; and the TLC chromstograms of the 10 species differ distinctly from each other.
