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-?-d-glucopyranosyl-(1?4)-O-?-d-glucopyranosyl-(1?4)-O-?-d-glucopyranoside (1), 3-(3'E-7'R,8'-dihydroxy-4',8'-dimethyl-3'-nonenyl)-2,5-dihydro-1,1-dioxo-thiophen 7'-O-?-d-glucopyranosyl-(1?4)-O-?-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-?-d-glucopyranosyl-6'-O-acetyl-(1?4)-O-?-d-glucopyranosyl-(1?4)-O-?-d-glucopyranoside (3), respectively, were isolated from the rhizomes of Trillium tschonoskii. Their structures were established on the basis of spectroscopic data, including HR-ESI-MS, IR, 1D and 2D NMR. The cytotoxic properties of the three compounds were investigated using human hepatic L02 cells.
