Iridoid glycosides from Gmelina arborea.
Three iridoid glycosides 6-O-(3''-O-benzoyl)-alpha-L-rhamnopyranosylcatalpol (1a), 6-O-(3''-O-trans-cinnamoyl)-alpha-L-rhamnopyranosylcatalpol (2a) and 6-O-(3''-O-cis-cinnamoyl)-alpha-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)-alpha-L-rhamnopyranosylcatalpol (4) was also isolated and identified.
