Abstract

The new natural flavanones (+)-5,2′-dihydroxy-6,6′,7-trimethoxyflavanone and (+)-5,2′-dihydroxy-6,6′,7,8-tetramethoxyflavanone in addition to the known flavones chrysin, norwogonin, and wogonin were isolated from Scutellaria phyllostachya roots. The structures of the isolated compounds were established using IR, UV and PMR spectra.
