Objective: To study the effects of potentill on all systems of experimental animals to provide experimental evidence for the comprehensive safety evaluation of potentill.Methods: Mice and rats were given potentill orally to determine the influence on all systems, and the general pharmacological activities of potentill were recorded.Results: The general behavior of mice was normal after the adminisration of potentill , the test samples showed no synergetic hypnotic effect with nembutal at subthreshold dose, and had no influence on the spontaneous activity and body coordination ability of mice (P>0.05).The test samples showed no obvious influence on the cardiovascular system and respiratory system of rats (P>0.05).Conclusion: Potentill meets the general requirements of pharmacology at the prescribed dose.

Objective To establish an HPLC method for the determination of ginsenosides Rg1 and Re in Shenqi Granula.Methods Chromasil C18 column(250 mm?4.6 mm)was used with acetonitrile-0.05% phosphoric acid solution(21∶79)as mobile phase.The flow rate was 1 mL/min and the detected wavelength was 203 nm.Results Ginsenosides Rg1 and Re could be baseline separated with in 30 min.The average recovery rates were 99.60% and 98.5%,corresponding RSD were 1.93% and 2.31% for ginsenoside Rg1 and Re,respectively(n=5).Conclusion This method is fast and accurate and can be used for quality control of Shenqi Granula.
