RESUMO
OBJECTIVE: To the amount of baicalin in Banxiaxiexintang Decocted of different combinations were determined by PR-HPLC. METHOD: An YWG C18 column was used with a mobile phase of MeOH-H2O-H3PO4(47:53:0.05) and an UV detector at the wavelength of 274 nm. RESULT AND CONCLUSION: The amount of baicalin decreases when Radix Scutellariae is decocted with Rhizoma Coptidis, Rhizoma Pinelliae and Rhizoma Zingiberis.

RESUMO
OBJECTIVE: To the amount of 1,8-cineole in Banxiaxiexintang Decoction different combinations were determined by GC. METHOD: An OV-101 column (30 m x 0.32 mm) was used at 90 degrees C. RESULT AND CONCLUSION: The amount of cineole was 2-3 times in each combination than that in the separate Rhizoma Zingiberis.
