[Objective] To optimize the extraction technology of total saponins from Allium wallichii Kunth. [Methods]Effects of liquid-solid ratio,ethanol concentration,extraction temperature and extraction time were researched by single factor test. Extraction technology of total saponins from A. wallichii Kunth was optimized by L9( 34) orthogonal test. [Results]The optimal extraction technology was 50∶ 1 mL /g liquid-solid ratio,60% ethanol concentration,2. 5 h extraction time and 50 ℃ extraction temperature. Under this condition,the extraction rate of total saponins from A. wallichii Kunth was 1. 20%. [Conclusions] This extraction technology was simple and convenient,and could be used for the extraction of total saponins from A. wallichii Kunth.
