摘要

目的: 制定扁桃叶药材的质量标准

为该药用植物资源的开发利用提供科学依据。方法: 根据2010年版《中国药典》方法

鉴别扁桃叶药材的性状、显微特征;检查水分、总灰分、酸不溶灰分;采用薄层色谱(TLC)法进行定性鉴别;采用高效液相法测定芒果苷的含量。结果: 对扁桃叶药材的性状、显微特征进行了描述;根据10个不同产地扁桃叶测定结果

确定水分不得过12%

总灰分不得过16%

酸不溶灰分不得超过5%。浸出物以稀乙醇为溶剂

热浸法测定

浸出物不得少于23%。TLC斑点清晰

分离度好;芒果苷的进样量在0.4~1.4 μg(r=0.999 9)与峰面积积分值呈良好线性关系

平均回收率为100.45%

RSD 1.59(n=10)

芒果苷含量不得少于2%。结论: 所建标准可用于扁桃叶药材的质量控制。

Abstract

Objective: To provide scientific basis for the utilization and development of the leaves of Mangifera sylvatica by establishing tis quality control standard. Method: According to Chinese Pharmacopeia (2010 ediction)

the property and microscopic characterstics of M. sylvatica

moisture

total ashes content

acid-insoluble ashes content were identified by TLC.The content of dinsenoside mangiferin in M. sylvatica was determined by HPLC. Result: Macroscopic and microscopic characteristics of M. sylvatica were described.The moisture in the leaves was below 12%

with the total ash content of 16%

the content of acid-insolubal ash was equal or below 5%.The content of hot homeopathic alcohol was above 23%.The spot of TLC were clear and well-sparated.The linear range of dinsenoside mangiferin were 0.4-1.4 μg(r=0.999 9);the average recoveries were 100.45% and RSD of them were 1.59%;the contents of mangiferin in the leaves were above 2%. Conclusion: The quality standard is suitable for the leaves of M. sylvatica.
