Study on purification process of total saponins of Rubus parvifolius L.with macroreticular resin / 中成药

ABSTRACT

Objective: To study the technological parameters of the purification process of total saponins of Rubus parvifolius L. with macroreticular resin. Methods: The adsorptive characteristics and elutive parameters of the process were studied by taking the elutive and purified ratio of total saponins of Rubus parvifolius L. as marker. Results: 19.3mL of the extractive of total saponins of Rubus parvifolius L. was purified with a column of macroreticular resin (R1cm?H20cm,dried weight 2.68g) and was washed with 100mL of distilled water, then was eluted with 100mL of 50% ethanol. Conclusion: With macroreticular resin to adsorb and purify, the elutive ratio of total saponins of Rubus parvifolius L. was over 79.2% and the purity reached 55.3%. So this process of applying macroreticular resin to adsorb and purify total saponins of Rubus parvifolius L. is feasible.
