title: Kakispyrol, a new biphenyl derivative from the leaves of Diospyros kaki.
abstract: A new biphenyl derivative, 4',5-dimethoxy-3-beta-D-glucopyranosyloxy-4-hydroxy-biphenyl, named kakispyrol (1), has been isolated from the leaves of Diospyros kaki, together with three known compounds, vitexin (2), 2'-O-rhamnosyl vitexin (3) and isorhamnetin-3-O-beta-D-glucopyranoside (4). The structure of compound 1 has been determined on the basis of spectroscopic evidence.
