A glycoside, mp 209-220 deg C (decomp), D -142 degree, C47H70O24, named trillenoside A (I), was isolated from the rhizomes of Trillium kamtschaticum PALL (Liliaceae).The structure of its aglycone (designated trillenogenin, II), mp 250-251 deg C, D -198 degree, C26H36O8, was determined by X-ray crystallographic analysis of the tetraacetyl monobrosyl derivative, mp 242-244 deg C (dec.), D -112 degree, C40H47BrO14S, and I was characterized as 15-oxo-18-nor-25R-spirosta-5,13-diene-1β,3β,21,23α,24β-pentaol-1-O-β-D-apiofuranosyl-(1->3)-α-L-rhamnopyranosyl-(1->2)-3)>-α-L-arabinopyranoside.I is thus a novel type of steroid glycoside, noteworthy in that the aglycone is an 18-nor-spirostane derivative having an enone system in the D-ring and hydroxyl groups at C21 and in the F-ring, and also in that the sugar moiety is a branched-chain tetrasaccharide containing apiose.Keywords - trillenoside A; 15-oxo-18-nor-spirostadiene-pentaol tetraglycoside; Trillium kamtschaticum PALL; structure determination; trillenogenin; X-ray analysis
