Study on Purification Process of Ginsenosides with Macroreticular Resin / 中成药

ABSTRACT

Objective: To study the technological parameters of the purification process of ginsenosides with macroreticular resin. Methods: The adsorptive characteristics and elutive parameters of the process were studied by taking the elutive and purified ratio of ginsenosides as marker. Results: 45ml of the extractive of ginseng (5.88mg/ml) was purified with a column of macroreticular resin (R15mm?H90mm, dried weight 2.52g) and washed with 100ml of distilled water, then eluted with 100ml of 50% ethanol. Conclusion: With macroreticular resin to adsorb and purify, the elutive ratio of ginsenosides was above 90% and the purity reached 60.1%. So this process of applying macroreticular resin to adsorb and purify ginsenosides is feasible.
