OBJECTIVE: To improve the quality standard for Fufang haqing tablets. METHODS:Radix Peucedani, Fructus Schisandrae Sphenantherae in the recipe were identified by TLC, and the content of Astragaloside Ⅳ was determined by HPLC-ELSD method.RESULTS:Radix Peucedani and Fructus Schisandrae Sphenantherae showed clear TLC spots and good resolution. Astragaloside Ⅳ showed a good linear relationship within the range of 1.447 2～16.080 0 ?g (r=0.999 6). The average recovery was 99.68% with the RSD at 1.16%(n=6). CONCLUSION: The established method further improved the quality standard of Fufang haqing tablets.

OBJECTIVE: To compared the similarity between Cordyceps Sinensis and Solid Fermentation of Cordyceps Militaris in chemical components by TLC. METHODS: The similarity in total constituents and different extract fractions were compared between Cordyceps Sinensis and Solid Fermentation of Cordyceps Militaris by TLC. RESULTS: Solid Fermentation of Cordyceps Militaris and Cordyceps Sinensis were basically similar in that their TLC spots occurred at the corresponding place except a slight difference in size. CONCLUSION: Cordyceps Sinensis and Solid Fermentation of Cordyceps Militaris have similar chemical constituents, which remains to be further studied.

OBJECTIVE:To establish the quality standard of Baji zhenyang tablets.METHODS:Panax ginseng,Herba Epimedii and Carthamus tinctorius in the tablets were identified by TLC,and the content of icariin in Herba Epimedii was determined by HPLC.RESULTS:The TLC spots of P.ginseng,Herba Epimedii and C.tinctorius were distinctive and well-separated.The linear range of icariin was 0.080 04～0.640 32 ?g(r=0.999 8).The average recovery was 101.29%(RSD=0.98%,n=6).CONCLUSION:The established standard is applicable for the quality control of Baji zhenyang tablets.
