Abstract: Two new sterodal saponins (Lieguonin-A and Leiguonin-B) iso-lated from root of Tacca plantaginea(Hance) Deenth were characterized as yamogenin-3-O-β-D-glucopyranosyl(1→2)[-α-L-rhamnopyranosyl (1→3)][-α-L-rhamnopyranosyl(1→4)][-β-Dglucopranoside and yamo-genin -3-O-α-L-rhamnopyranosyl(1→2)][-α-L-rhamnopyranosyl(1→3)][-β-D-glucopyranoside on basis of chemical and 1H NMR,13C NMr ,MS, IR spectral data.

Key words: Tacca plantaginea
