title: Chemical constituents of the leaves of Diospyros kaki and their cytotoxic effects.
abstract: Isolation and structure elucidation of two new compounds, kakispyrone (1) and kakisaponin A (2), together with 11 known compounds, from the leaves of Diospyros kaki L. are described. Their cytotoxic effects against several cancer cell lines (A549, HepG2 and HT29) are also reported.
