Abstract:
From seeds of Strychnos nux-vomica three iridoids, 6′-O-acetylloganic acid, 4′-O-acetylloganic acid and 3′-O-acetylloganic acid were isolated together with two known iridoid glucosides, loganic acid and 7-O-acetylloganic acid. The structures of the compounds were established by ESI-MS and by 1D and 2D NMR spectroscopic methods.
From the seeds of Strychnos nux-vomica three iridoids and two known iridoid glucosides were isolated. The molecular structures of the compounds were established by ESI-MS and NMR studies.
