The influence of phenological Stages on chemical composition of Scutellariae Radix (SR),the root of Scutellaria baicalensis Georgi, was investigated.In order to deal with a large quantity of samples, a rapid ultra-performance liquid chromatographic (UPLC) was first developed and validated for the simultaneous quantification of five flavonoids, namely baicalin (baicalein-7-O-β-D-glucuronide, BG), wogonoside (wogonin-7-O-β-D-glucuronide,WG), baicalein (BA), wogonin (WO), oroxylin A (OA) in the samples.
