A flavanone and a dihydrodibenzoxepin from Bauhinia variegata

Phytochemistry. 2003 Oct;64(4):879-82. doi: 10.1016/s0031-9422(03)00416-3.

Abstract

Phytochemical analysis of the root bark of Bauhinia variegata Linn yielded a new flavanone, (2S)-5,7-dimethoxy-3',4'-methylenedioxyflavanone (1) and a new dihydrodibenzoxepin, 5,6-dihydro-1,7-dihydroxy-3,4-dimethoxy-2-methyldibenz [b,f]oxepin (2) together with three known flavonoids (3-5). The structures of the new compounds were determined on the basis of spectral studies.
