Four new iridoid glycosides, named L-phenylalaninosecologanin (1), 7-O-(4-β-D-glucopyranosyloxy-3-methoxybenzoyl)secologanolic acid (2), 6′-O-(7α-hydroxyswerosyloxy)loganin (3) and (Z)-aldosecologanin (5), were isolated, together with a known one, newly named (E)-aldosecologanin (4), from the stems and leaves of Lonicera japonica. Their structures were established on the basis of chemical and spectral data.
