Four new N-contained iridoid glycosides from flower buds of Lonicera japonica.
Four new N-contained iridoid glycosides, lonijapospiroside A (1), L-phenylalaninosecologanin B (2), L-phenylalaninosecologanin C (3), and dehydroprolinoylloganin A (4), were isolated from the flower buds of Lonicera japonica Thunb.
