Abstract

The effects of the HIPEF- assisted extraction of ursolic acid from Huizhou Gongju were preliminary investigated,in which the technical parameters were optimized.The optimal conditions were as follows: electric field intensity of 30 k V / cm,pulse number of 2,material- solvent ratio of 1 ∶ 12 and 30℃. Under these conditions,the extraction yield of ursolic acid can reach to 97.577%.The results showed that the X-5 macroporons resin had the best effect on the separation when the volume of drug 60 BV with the adsorption- speed 2BV / h,p H11,and the volume of 70% ethanol with desorption- speed 2BV / h,and the purity of ursolic acid could reach to 85%.
