Objective To study the optimum extraction process of sinomenine which exist in Miao medicine named Diploclisia affinis,and to extend the applications of minority medicine. Methods Using Acid-alkali method to extract sinomenine from the Diploclisia affinis,investigating the effects of extract solvent’s dosage and pH value,the alkalify solvent’s pH value on extraction rate of sinomenine,HPLC was used as detection method. Results Factors influencing sinomenine’s extraction rate followed a descending order of extract solvent’s pH value, alkalify solvent’s pH value and extract solvent’s dosage. It showed that the optimum extraction process was extract solvent’s pH value was 3,lkalify solvent’s pH was 7 and extract solvent’s dosage was 1∶10. Conclusion When applied the optimum extraction process to extract the sinomenines,the extraction rate was stability and closed to the orthogonal experimental results.The extraction method is rational and feasible.
