STEROID SAPONINS FROM POLYGONATUM KINGIANUM

Article abstract of DOI:10.1016/0031-9422(92)83727-G

Four new steroid saponins, kingianosides A-D, were isolated from the rhizome of Polygonatum kingianum, together with two known steroid saponins.On the basis of chemical and spectral evidence, the structures of kingianosides A-D were established as gentrogenin 3-O-β-D-glucopyranosyl(1->4)-β-D-galactopyranoside, gentrogenin 3-O-β-D-glucopyranosyl(1->4)-β-D-fucopyranoside, 26-O-β-D-glucopyranosyl-22-hydroxy-25(R)-furost-5-en-12-on-3β,22-diol 3-O-β-D-glucopyranosyl(1->4)-β-D-galactopyranoside and 26-O-β-D-glucopyranosyl-22-hydroxy-25(R)-furost-5-en-12-on-3β,22-diol 3-O-β-D-glucopyranosyl(1->4)-β-D-fucopyranoside, respectively.Key Word Index: Polygonatum kingianum; Liliaceae; rhizome; steroid saponins; gentrogenin; kingianosides A, B, C and D.
