Two new secoiridoid glycosides, swertiajaposide A (1) and swertiajaposide B (2), a new unsaturated alcohol 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.
