Abstract:Total paeony glycoside was extracted by tissue-smashing extraction and the extraction conditions were optimized by orthogonal test using the content of total paeony glycoside as main indices. The results showed that the optimum extraction conditions were as follows: liquid-solid ratio 30:1, soaking time 6 h, extraction time 2 minutes and extraction voltage 70 V, under which the total paeony glycoside yield was up to 4.84%.
