As a part of studies on the quality control of crude drug preparation, So-Shi-Ho-Tang, index components of Scutellariae Radix were identified by TLC and quantified by HPLC. Wogonin and baicalein were identified in ethyl ether fraction on silica gel plate with benzene/ethyl acetate (1 : 1, v/v). The content of baicalin was determined by HPLC on ${mu}-Bondapak;C_18$ column with 0.5%-phosphoric acid/acetonitrile (73 : 27, v/v). Its recovery rate in the extract granules, compared to the content in the Scutellariae Radix, was $52.1;{pm};0.7%$.
