title: Three novel sesquiterpene glycosides of Sarcandra glabra.
abstract: Three new sesquiterpene glycosides, 8 beta,9 beta-epoxy-4 alpha-hydroxy-5 alpha H-lindan-7(11)-en-8 alpha,12-olide-15-O-beta-D-glucopyranoside (1, sarcaglaboside F), 4 alpha-hydroxy-5 alpha,8 beta H-lindan-7(11)-en-8 alpha,12-olide-15-O-beta-D-glucopyranoside (2, sarcaglaboside G), 4 alpha-hydroxy-5 alpha,8 beta H-eudesman-7(11)-en-8 alpha,12-olide-15-O-beta-D-glucopyranoside (3, sarcaglaboside H), together with five known compounds, chloranoside A (4), sarcaglaboside C (5), dihydrovomifoliol-O-beta-D-glucopyranoside (6), 9-hydroxy-heterogorgiolide (7) and chloranthalactone B (8), were isolated from Sarcandra glabra THUMB. NAKAI. The structures and relative configurations of three new compounds were determined on the basis of their spectroscopic data and chemical evidence.
