Abstract

A non-glycosidic iridoid, campsinol (1), and two iridoid glucosides, 7-O-(Z)-p-coumaroylcachineside V (2) and 7-O-(E)-p-coumaroylcachineside I (3), were isolated from the fresh flowers of Campsis grandiflora along with five known iridoid glycosides, ixoroside (4), campsiside (5), cachineside I (6), 5-hydroxycampenoside (7), and 5-hydroxycampsiside (8), and two known phenylpropanoid glycosides, acteoside (9) and leucosceptoside A (10). The structures of these compounds were determined based on the NMR and Mass spectroscopic data and other chemical evidences.
