目的建立雪梨膏的含量测定方法。方法采用紫外分光光度法测定雪梨膏中绿原酸类多酚化合物的含量。结果检测波长为329nm,绿原酸在3.5-28.2μg/m L线性关系良好(r=0.9998);平均回收率95.59%;有较好的精密度、重复性及稳定性。结论本方法简便、准确,重现性好,可用于雪梨膏的含量测定
Objective To establish the method of determination of Sydney cream. Methods The content of chlorogenic acid polyphenols in Xueli paste was determined by ultraviolet spectrophotometry. The results showed that the detection wavelength was 329 nm, the linear relationship between chlorogenic acid and 3.5-28.2 μg / ml was good (r = 0.9998). The average recovery was 95.59%. The precision, repeatability and stability were all good. Conclusion This method is simple, accurate, reproducible, and can be used for the determination of Sydney cream
