Structure-activity relationship of eight high content flavonoids analyzed with a preliminary assign-score method and their contribution to antioxidant ability of flavonoids-rich extract from Scutellaria baicalensis shoots

Investigation of flavonoids-rich extract from Scutellaria baicalensis shoots shows that 15 of the 19 flavonoids detected with UPLC-Q-TOF-MS were identified, and it exhibited high antioxidant abilities with IC50 at 70.81, 35.34 and 33.27 μg/mL in DPPH, ABTS and CAA assays, respectively. An order of a...
