title: Studies on the constituents of Swertia japonica Makino II. On the structures of new glycosides.
abstract: Two new secoiridoid glycosides, swertiajaposide A (1) and swertiajaposide B (2), a new unsaturated alco-hol glycoside, 3-butenyl 6'-O-alpha-L-arabinopyranosyl-beta-D-glucopyranoside (3), and a new lignan glycoside, 7R,7'R,8S,8'S-(+)-neo-olivil-4-O-beta-D-glucopyranoside (4), were isolated together with six known compounds from the whole plants of Swertia japonica Makino. The structures of the new compounds were elucidated on the basis of chemical and spectroscopic evidence.
