Viscidulin III (17.4 microM), wogonin (17.4 microM) and luteolin (18.4 microM) were more effective than baicalein (23.0 microM) which reportedly inhibits the proliferation of some cancer cell lines.

Chromatographic methods were used to separate compounds, spectral methods were used to determine the structures and bioactivities of the flavonoids were screened in several models in vitro. Nine compounds were isolated and identified as baicalein (1), wogonin (2), oroxylin A (3), 5, 7, 2', 6'-tetrahydroxyflavone (4), Viscidulin III (5), baicalin (6), wogonoside (7), oroxylin A-7-O-beta-D-glucuronide (8) and chrysin-6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (9)[1]
