Abstract: Objective To explore the optimal conditions for extraction of Polygala fallax Hemsl. Methods Various trials were conducted to extract P. Fallax Hemsl. With L_(16) (4~5) orthogonal experiments. Results The optimal experimental parameters for extraction were 95% ethenol, dosage-liquor ration at 1:5, three-times extraction at 75℃, 1.5 hours for each extraction, and extraction rate at 11.89%. Conclusion Orthogonal test is convenient and accurate in extracting P. Fallax Hemsl.
