Abstract
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.
