title: Secoiridoid glycosides from Gentiana scabra.
abstract: Six new secoiridoid glycosides, gentiascabraside A (1), 6beta-hydroxyswertiajaposide A (2), 1-O-beta-d-glucopyranosyl-4-epiamplexine (3), and scabrans G3 (4), G4 (5), and G5 (6), have been isolated from the rhizomes and roots of Gentiana scabra together with a known compound, swertiajaposide A (7). The structures of the new compounds were determined by spectroscopic (NMR, MS) and chemical means.
