| Abstract: | Objective ：To study how to extract, abstract and determine dencichine in water-solubility ingredients of Radix Notoginseng. Method ： Crude of dencichine was extract with ultrasonic extraction. Then it was precipitated by ethanol, and purified by sephadex column and ion exchange resin column to obtain dencichine. At last dencichine was assayed by HPLC. Resuh：Dencichine had been successfully extracted and abstracted, and its purity was 92. 41%. Conclusion：Multi-column chromatography can obtain more purified dencichine successfully. |
