Three iridoid glycosides 6-O-(3″-O-benzoyl)-α-l-rhamnopyranosylcatalpol (1a), 6-O-(3″-O-trans-cinnamoyl)-α-l-rhamnopyranosylcatalpol (2a) and 6-O-(3″-O-cis-cinnamoyl)-α-l-rhamnopyranosylcatalpol (3a) were isolated from aerial parts of Gmelina arborea and structures were elucidated by spectral analysis. Additionally a known iridoid 6-O-(3″, 4″-O-dibenzoyl)-α-l-rhamnopyranosylcatalpol (4) was also isolated and identified.
