Results: The extracting solution of the Radix Pulsatillae and it's masculine comparison have the biggest absorption in(201±1)nm,and have the same UV -spectrum.The extractive of Hedyotis difusa Willd and Herba Sar- candrae were assayed by TLC.The results were consistent with the controles.The average content of ethanol-soluble extractive of the samples was 38.8 mg/g.The weight variation,water content,disintegration time,microbiological timiting,test conformed with Chinese pharmacopoeia. Conclusion: This method is simple,accurate,and can be used as the quality control of Changtai capsules.
