摘要
目的:建立蒙药三味散中的没食子酸的含量测定方法。方法:采用HPLC法测定蒙药三味散中没食子酸的含量,检测波长为273nm,色谱柱(C 18,5μm,4.6 mm×250 mm),流动相为甲醇~0.3%磷酸缓冲液(1∶9)。结果:没食子酸在0.44~4.4μg范围内呈现良好的线性关系(R2=0.9992),平均回收率为100.78%,RSD为1.79%。结论:采用该方法测定没食子酸的含量,操作简便、准确可靠,可用于蒙药三味散中没食子酸的含量测定方法。
Objective: To establish a suitable method for Determination of Gallic Acid in 3 powder and Provide a reference of Gallic acid extraction process and quality standards. Methods: Using HPLC to investigating chromatographic conditions. The following chromatographic conditions is that the detection wavelength was 273 nm,column( C 18,5μm,4. 6 mm × 250 mm),mobile phase was methanol ~0. 3% phosphoric acid buffer solution( 1 ∶ 9),the injection volume was 10 u L. Results: Preparation of sample solution,reproducibility,linear range,precision,stability and recovery are in line with the relevant requirements. Conclusion: The method is scientific,reasonable and feasible and it was in line with simple,rapid and accurate requirements,and this also made a foundation for Gallic acid research.
