result sql = OBJECTIVE : To develop a simple, reliable approach for evaluating the quality of Huangqin (Scutellaria baicalensis).

METHOD : To determine the DPPH free radical scavenging activity and assay of four bioactive components: baicalin, baicalein, wogonin and wogonin-7-O-glucuronide by HPLC.

RESULT : The correlative relationship between DPPH free radical scavenging activity and baicalin content was obtained.

CONCLUSION : Bioassay of DPPH free radical scavenging activity could be used as one of the methods for quality evaluation of Chinese drug Huangqin.
