Main flavonoids in the root of Scutellaria baicalensis cultivated in Europe and comparison their antiradical properties.

Original language description

The content of main flavonoids in the root of Scutellaria baicalensis Georgi cultivated in Central Europe was evaluated by using new simple RP-HPLC method with gradient of acetonitrile in mobile phase. The main components of the roots were baicalin (8,12% of dry root mass) and wogonin glucuronide (2,52 %). The content of flavonoids was comparable with the content in plants cultivated in natural localities. Five main flavo-noids were evaluated for their scavenging ability with DPPH radical-generating system and due to limited solubility only two flavonoids were investigated for their ability to scavenge hydroxyl radical by the method aromatic hydroxylation. The total extract was also tested in both the experimental arrangements. In experiments with DPPHonly baicalin and baicalein displayed significant scavenging effect, while the production of OH radical generated by UV photolysis of H2O2 was considerable decreased in the presence of baicalin and wogonin glucuronide.
