Abstract

Objective:To prepare Radix Sesali dropping pills and establish their quality control methods.Methods:The dropping pills were prepared by a conventional method,TLC was used to qualitatively identify osthole in the dropping pills,the HPLC method was used to determine the content of osthole.Results:The dropping pills were well distributed in size,smooth and glossy in appearance,mild in hardness.The TLC spots were fairly clear and the negative control showed no interference.The linear range of osthole was 0.202～2.424μg,with a correlation coefficient of 0.9997.The average recovery and the RSD were 100.22% and 1.31% respectively.Conclusion:The preparing technology is rational and available.The method is sample and reproducible for the quality control of Radix Sesali dropping pills.
