AIM To study the chemical constituents of Dioscorea parviflora. METHODS The chemical constituents were isolated by silica gel and RP-18 column chromatography, and their chemical structures were elucidated by IR, NMR and MS. RESULTS Eleven steroides have been isolated from EtOH extract of Dioscorea parviflora and identified as isonarthogenin 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranoside (I), diosgenin-diglucoside (II), prosapogenin A of dioscin (III), dioscin (IV), deltonin (V… CONTINUE READING
