Article abstract of DOI:10.1016/0031-9422(80)85067-9

A new spirostanol glycoside isolated from aerial parts of Dioscorea tenuipes was characterized as 5β,25-L-spirostan-1β,2β,3α,4β-tetrol (1β-hydroxydiotigenin or 4β-hydroxyneotokorogenin) 1-O-α-L-arabinopyranoside on the basis of chemical and 1H NMR spectral data. - Key Word Index: Dioscorea tenuipes; Dioscoreaceae; structure determination; 1H NMR; spirostan-tetrol glycoside; 1β-hydroxydiotigenin 1-O-arabinoside.
