锁阳不同生长期鞣质含量的动态研究

Study on Dynamics of Tannin in Different Growth Phase of Cynomorium songaricum

本文用高锰酸钾法和络合滴定法测定不同生长期野生与人工种植锁阳的鞣质含量。结论表明,锁阳鞣质含量呈现规律性变化,以出土期含量较高。如仅以鞣质作为其有效成分之一,出土期所采集的锁阳药材质量较好。该结果为锁阳药材的质量评价提供了一定的科学依据。

Potassium permanganate titration and complexometry were used to determine the content of tannin in different growth phase of wild and cultivated Cynomorium songaricum Rupr. The result showed that the content appeared regularly changing and the content in coming-up phase was higher than other phases. The quality in this phase would be better if the tannin was regarded as one of the effective components. The result might provide science foundation for the quality control of Herb Cynomorii.
