[Isolation and properties of saponins from rhizomes of Dioscorea deltoidea Wall].
From the rhizome D. deltoidea a new trisaccharide of diosgenine has been isolated.  This compound is diosgenine-3 (alpha-L-rhamnopyranosyl (1-->2gl)-beta-D-glucopyranosyl-(1-->4 gl)-beta-D-glucopyranoside.  This trisaccharide has been termed deltonine.  The rhizome D. deltoidea has also displayed furostanolic tetrasaccharide which is a mixture of delta5-furostene-3beta, 22, 26-triol-3beta-deltotrioside-26beta-D-glucopyranoside and its alkoxyderivative.  This tetrasaccharide has been termed deltoside.  The rhizome has also small quantities of diosgenine-3-beta-D-glucopyranosyl (1-->4)-beta-D-glucopyranoside.
