Abstract

Objective To choose the bestway of extracting procedure of Rhizoma corydalis. Methods The optimal extraction process is selected with the orthogonal design. The content of corydalis B and the yield of extracts were used to evaluate the factor levels. Results The ideal extraction process is:extracted with 75% alcohol for 2 times, first 6 times amount, soaked 0.5 h, refluxed 1.5 h, then 4 times amount, refluxed 1.5 h. Conclusions This extractive condition is the best way.
