Abstract: Objective:To optimize the aqueous extraction process of Wuteng Jiangya Tablets. Methods:The extraction rate and amount of 2,3,5,4’-tetrahydroxy-stilbene-2-O-β-D-glycoside extraction as indexes,the times for decoction,decocting duration,the water addition,immersion time were optimized by L9(3)4 orthogonal test. Results:The optimal extraction process was that herbs in the ratio of prescription were decocted for two times in the water,and the amounts were equal to six times,don’t need to soak,two hours each time. Conclusion:The optimized process is reasonable with good repeatability and stable quality in samples.
