title: Secoiridoid glycosides from Gentiana scabra.
abstract: Two new secoiridoid glycosides, 4'-O-beta-D-glucopyranosylgentiopicroside (1) and 6'-O-beta-D-glucopyranosylgentiopicroside (2), have been isolated from the rhizomes and roots of Gentiana scabra together with three known compounds, olivieroside, 1-O-beta-D-glucopyranosylamplexine, and benzyl alcohol O-alpha-L-arabinopyranosyl (1 --> 6)-beta-D-glucopyranoside. The structures of 1 and 2 were elucidated using chemical and physicochemical (MS and NMR) studies.
