A novel C-glycosylflavone from the leaves of Diospyros kaki.
A novel C-glycosylflavone with unusual alpha-orientation at the anomeric center of d-glucose was isolated from the leaves of Diospyros kaki. Its structure was determined as 8-C-[alpha-l-rhamnopyranosyl-(1 --> 4)]-alpha-d-glucopyranosylapigenin by chemical methods and spectral experiments.
