摘要
采用重量法测定本品中的总皂甙含量,操作简便、快速,结果准确可靠,方法的回收率平均97.6％,CV值为0.78％。比色法,虽然常应用于人参皂甙的含量测定中,但因显色反应的影响因素太多,测定结果的准确度、精密度并不理想,结果证明重量法更为适合。
A gravimetric method for determining the total saponin content in Xuesuantong capsule has been developed. The proposed method has the advantages of efficiency, simplicity and accuracy. The average recovery rate is 97.6％ with a relative standard deviation of 0.78％. AHhough colorimetrg has been employed commonly, there were many factors affecting colour reaction, so thatthe result was not ideal. Now the gravimetric method is applied to control the quality temporarily during the period of clinisal study.
