Objective:To optimize the extraction process of Fufang Jiangzhi granule. Methods:The effect factors of temper-ature,time of extraction,volume of ethanol and concentration of ethanol to solvent on flavonoids extracted from Fufang Jiangzhi granule were studied through orthogonal test. Results:The optimum extracting conditions of Fufang Jiangzhi gran-ule were as follows:adding 20 times quantity of 70% ethanol,boiling 2 times and 1.5 hour each time. Under the above conditions,rate of extractum was 12.5%,percent content of flavonoids was 4.49%. Conclusion:This technological process is stable and feasible.
