We analyzed a total of 34 compounds by HPLC: 3,4[prime]-dihydroxypropiophenone-3-glucoside (DHPPG), (+)-catechin, nine cinnamic acid derivatives, 15 flavonol glycosides, and eight flavone aglycones.
Among the compounds tested the baicalein derivative 14 was the most active, showing an [IC.sub.50] value of 30.40 [+ or -] 1.28 [micro]M, very similar to the precursor baicalein (13) ([IC.sub.50] = 35.09 [+ or -] 4.13 [micro]M), suggesting that the presence of 8-(dimethylamino)methyl group on the flavone skeleton did not significantly alter its ability to scavenge free radicals.
