title: Iridoids and secoiridoids from Guettarda platypoda.
abstract: A reinvestigation of the roots of Guettarda platypoda afforded in addition to morronoside and sweroside isolated previously further two iridoids, loganic acid and loganin and a rare secoiridoid, secoxyloganin. The structures were elucidated by NMR techniques. This is the first report of the isolation of such compounds from G.platypoda. Some chemotaxonomic conclusion can be drawn.
