瑶药水灯盏质量标准研究

Study on Quality Standard for Yao Medicine Kadsurae Oblongifoliae Radix et Caulis

目的：建立瑶药水灯盏的质量标准。方法：采用生药学和薄层色谱法对其进行研究，测定水分、灰分和浸出物的含量。结果：对水灯盏的性状、显微特征进行了描述；对10批样品进行了薄层色谱鉴别；对总木脂素的含量进行了测定。实验结果得出水分不得过15．0％，总灰分不得过5．0％，酸不溶性灰分不得过1．0％，95％乙醇浸出物不得少于11.0％。结论：较全面考察了水灯盏的各项质量指标，能有效评价水灯盏的质量。

Objective： To establish the quality standards for Yao. Methods： Kadsurae Oblongifoliae Radix et Caulis. Methods The pharmacognostics and thin layer chromatography （TLC） were used. The content of the moisture, the ash and the extracts were analyzed. Results： The character, microscopic characteristic and TLC identification of Kadsurae Oblongifoliae Radix et Caulis were reported. Water content should be not more than 15.0%, total ash not more than 5.0%, acid insoluble ash should not more than 1.0% and ethanol extract not less than 11.0%. Conclusion： The results were suitable for the quality control of Kadsurae Oblongifoliae Radix et Caulis.
