Abstract: In order to determine the ZTC1+1 II type natural clarifying agent used for notoginseng (Panax notoginseng) leaves and steams glycosides extract the best technology of removing impurity,on the basis of single factor analysis,the concentration of drug quality,clarifying agent dosage,temperature is the independent variable,saponin content and solids removal rate as evaluation index,establishing three factors and three levels of Design- Expert response surface analysis method.The results show that the best process of Panax notoginseng leaves and steamspurificationis as followsThe mass concentration of liquid is0.19 g/mL,the order of ZTC1+1 II natural clarifier is first part A and after part B,the dosage of clarifiers B and A are 10% and 5% volume of the extract,respectively,and acting temperature is 40.Under this technological condition,the removal process of stem and leaf of Panax notoginseng is optimized,and the solid removal rate is 28.40%,the saponin retention rate is 92.22%,and the RSD is 1.74% and 0.56%,respectively.The repeatability is good,which verified the validity of the model.

Key words: stems and leaves of Panax notoginseng, ZTC1+1 II natural clarifier, saponins content, solid removal rate, response surface design
