目的:建立糙枝金丝桃药材质量标准,为该药的开发利用提供科学依据。方法:进行生药学研究,测定水分、灰分,薄层色谱鉴别,HPLC测定金丝桃苷的含量。结果:对糙枝金丝桃药材的性状、显微特征进行描述;供试品TLC色谱可显出金丝桃苷和芦丁的斑点,金丝桃苷的平均含量为0.424%。结论:实验结果可作为糙枝金丝桃药材的质量控制标准。
OBJECTIVE: To establish the quality standard of the rough branch Hypericum and provide a scientific basis for its development and utilization. Methods: The study of pharmacognosy, determination of moisture, ash, thin layer chromatography identification, HPLC determination of hyperoside content. Results: The properties and microscopic features of the Hypericum sp. Were described. The TLC chromatogram of the Hypericum sp. Showed hyperoside and rutin, the average content of hyperoside was 0.424%. Conclusion: The experimental results can be used as the standard of quality control for the crude drug Hypericum.
