摘要
采用煎煮法提取了查干-汤中的类黄酮,得到了棕色膏状类黄酮,用硝酸铝-亚硝酸钠方法测定了类黄酮的含量,求得其标准曲线的回归方程为y=0.0645x-0.2119,相关系数为r=0.9993,平均回收率为98.1-102.0%,RSD=0.92%(n=5).查干-汤中黄酮含量为1.04%.
The flavonoids was extracted from Chagan-tang with boiling method and its content was determined by aluminum nitrate-sodium-nitrite method. The regression equation is y=0.0645x-0.2119, and coefficient of correlation r=0.9993. The average recovery was 98.1-102.0%, RSD=0.92% （n=5）, flavonoid content 1.04%.
