Three New Sesquiterpene Glycosides from the Rhizomes of Trillium tschonoskii.

ABSTRACT: Three new sesquiterpene glycosides, possessing a rare aglycone with a sulfonyl between C-1 and C-15 positions, named 3-(3'E-7'R,8'-dihydroxy-4',8'-dimethyl-3'-nonenyl)-2,5-dihydro-1,1-dioxo-thiophen 7'-O-β-d-glucopyranosyl-(1→4)-O-β-d-glucopyranosyl-(1→4)-O-β-d-glucopyranoside (1), 3-(3'E-7'R,8'-dihydroxy-4',8'-dimethyl-3'-nonenyl)-2,5-dihydro-1,1-dioxo-thiophen 7'-O-β-d-glucopyranosyl-(1→4)-O-β-d-glucopyranoside (2), and 3-(3'E-7'R,8'-dihydroxy-4',8'-dimethyl-3'-nonenyl)-2,5-dihydro-1,1-dioxo-thiophen 7'-O-β-d-glucopyranosyl-6'-O-acetyl-(1→4)-O-β-d-glucopyranosyl-(1→4)-O-β-d-glucopyranoside (3), respectively, were isolated from the rhizomes of Trillium tschonosk
