双叶颗粒质量标准的研究

Study on Quality Standard of Shuangye Granule

建立功能食品双叶颗粒的质量控制方法。采用紫外分光光度法测定双叶颗粒中总黄酮含量，并对其方法学进行考察；同时对其理化和微生物指标进行检测。总黄酮含量在0.00-45.60μg/mL浓度范围内线性关系良好，r=0.9997，平均加样回收率为98.92%，RSD为1.43%。

To develop a method of quality control for Shuangye granule, the content of total flavonoids was de-termined by ultraviolet spectrophotometry and the methodology was studied;the physical, chemical and micro-bial indicators were detected. Total flavonoids had a good linearity over the concentration range of 0.00-45.60μg/mL（r=0.999 7）. The average recoveries was 98.92%with relatively standard deviations of 1.43%.
