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.

Preliminary studies in vitro blood coagulant effect of the main chemical constituent of Veromica peregri na,luteolin was carried out. Results showed that luteolin has fairly good blood coagulant effect

OBJECTIVE：To establish a convenient and efficient method for the determination of ferulic acid in Naofuqing capsule.METHODS:Ferulic acid in Naofuqing capsule was extracted with ethyl acetate by alkalization and acidification,and determined by TLC scanning method.RESULTS:The regression equation was y=127997.95x+1090.60，r=0.9996，(0.50～2.53μg).The average recovery is 98.28%(RSD 2.83%).CONCLUSION:The discribed method is simple，rapid and accurate for the determination of ferulic acid in Naofuqing capsule.
