Two new geranyl flavanones from Tephrosia villosa.
Two new geranyl flavanones, (2S)-5,4'-dihydroxy-7-O-[(E)-3,7-dimethyl-2,6-octadienyl]flavanone and (2S)-5,4'-dihydroxy-7-O-[(E)-3,7-dimethyl-2,6-octa-dienyl]-8-C-[(E)-3,7-dimethyl-2,6-octadienyl]flavanone, together with three known compounds, 7-O-methylglabranin, tephcalostan and 12a-dehydro-6-hydroxysumatrol, were isolated from the roots of Tephrosia villosa. The structures of these compounds were determined by extensive spectral studies.
