ABSTRACT
Objective To set up the quality standard of Wanbile Wan. Method s Fructus Psoraleae, Radix Puerariae, Radix paeoniae Alba and Radix Glycyrrhiza e Preparatae in Wanbile Wan were identified by TLC .Isopsoralen was determined b y TLC scanning. The chromatographic conditions were high performance silica gel G plate as lamellated plate, n- hexane - ethyl acetate (8 ∶ 2)being the exp ander, serrated scanning with single- wavelength reflection, beam stricture of 0.4? 0.4 mm, linear parameter SX=3 and scanning wavelength at 300 nm. Results The TLC spots were highly specific, clear and concentrated without interferen ce of the presence of negative controls. Isopsoralen showed a good linearity wit hin the range of 0.064~ 1.536 ? g, r=0.9980, average recovery rate was 100.7 % , and RSD was 2.0% .Conclusion This method can be used for the quality co ntrol of Wanbile Wan.
