Two new non-steroidal constituents from Dioscorea futschauensis R. Kunth.
Dioscorone A (1) and a new isocoumarin derivative (2) were isolated from the rhizome of Dioscorea futschauensis R. Kunth. The structures of 1 and 2 were elucidated on the basis of detailed analysis of NMR spectra. Their anti-fungal activity against Pyricularia oryzae and cytotoxic activity on K562 and HCT-15 cell lines were evaluated in vitro.
