Objective To study the preparing technology of asiaticosides with high purity. Methods Macroreticular resin column chromatography and recrystallization were used to optimize the preparing technology of asiaticosides. HPLC method was established for the contcent determination of asiaticosides. Results Centella asiatica was subjected to 75% ethanol distilment, water and acid precipitation, HPD100 macroreticular resin separation, and recrystallization in acetic ester. Then asiaticosides with high purity over 90% were obtained. Conclusion The process is stable and feasible, and it could be used for the preparation of high-purity asiaticosides.
