Abstract: OBJECTIVE:To establish the best method to determinate the quantity of anthraquinones in Zhuyu-fuzheng capsules. METHODS: Anthraquinones in Zhuyufuzheng capsules was determined by three methods. RESULTS: The average recovieries of two colorimetries and the new method were (99. 98 ± 2.21 )% 、 (102.56 ± 1.36)% 、(98.13 ±0.74)% respectively. However, the new method was simpler, quicker and more reproducible than any other one. By this method,the problem of stablility did not exist. CONCLUSION: All three methods can be used to determinate the quantity of anthraquinones in Zhuyufuzheng capsules. And the best method of three is the new one we established.
