The quality standard of Buxuetiaojing tablet was established.Herba Leonuri, Cortex Cinnamomi and Rhizoma Cyperi were identified by thin layer chromatog. (TLC).The content of stachydrine hydrochloride in Buxuetiaojing tablet was determined by thin layer chromatogram scanning.The methodol. study showed a good linear correlation in the range of 2.30-11.50 μg of stachydrine hydrochloride.The average recovery of stachydrine hydrochloride was 99.88%, and relative standard deviation (RSD) was 1.89%.In conclusion, TLC was a simple, accurate and reproducible method to determine the content.The quality standard of Buxuetiaojing tablet could be used for quality control of this tablet.

A method for determination of edaravone for injection by RP-HPLC was established.Kromasil C₁₈ column was used, with acetonitrile-acetate buffer (28:72) as a mobile phase at a flow rate of 1.0 mL/min.The wavelength of detector was 240 nm.The determination of edaravone showed a good linear relationship in the range of 6-120 mg/mL (r = 0.9996).The average recovery of cinobufagin was 100.6%, and RSD was 1.4% (n = 9).The method is simple, accurate, and precise, which can be used for the assay of edaravone for injection.

The quality standards of Shenfukang capsule was established by using thin-layer chromatog. (TLC) and high-performance liquid chromatog. (HPLC).The nature differentiation of Rhizoma Smilacis Glabrae and Herba Leonuri was determined by TLC.The content of rutin was determined by HPLC.The average recovery of was 100.6%, and RSD was 0.98%.The sep. degree of nature differentiation was kind, and the special attribute was strong.HPLC was accurate and reproducible to determine the content of rutin in Shenfukang capsule.The methods could be used to establish the quality standards in Shenfukang capsule.
