Abstract
Three new dibenz[b,f]oxepins: 6-methoxy-7-methyl-8-hydroxydibenz[b, f]oxepin (1), 1,8-dimethoxy-6-hydroxy-7-methyldibenz[b, f]oxepin (2), and 1-hydroxy-6,8-dimethoxy-7-methyldibenz[b,f]oxepin (3), along with two known dibenz[b,f]oxepins pacharin (4) and bauhiniastatin 4 (5), were isolated from Cercis chinensis Bunge (Leguminosae). Their structures were elucidated on the basis of spectroscopic evidence (EI-MS, UV, IR, (1)H, (13)C and 2D NMR). Compounds 1-5 were isolated from the Cercis genus for the first time.Entities:
