Vierh. Verbenaceae is a species of mangrove plant distributed in the coastal mangrove forests of Northern and Southern Vietnam. Using combined chromatographic separations three iridoid glucosides 2 -O- 4-methoxycinnamoyl mussaenosidic acid 1 2 -cinnamoyl-mussaenosidic acid 2 marinoid D 3 and a lignan glucoside syringaresinolf-D-glucopyranoside 4 were isolated from the methanol extract of leaves of mangrove plant Avicennia marina. Structures of the isolated compounds were elucidated by spectroscopic methods including one dimesional 1D - and 2D - NMR electrospray ionization mass spectrometry ESI - MS and also by comparison with the literature data. Compound 4 is reported for the first time from this plant. Keywords Avicennia marina iridoid glucoside lignan glucoside. 1. Introduction Avicennia marina Forsk. Vierh. Verbenaceae is a species of mangrove plant distributed in the coastal mangrove forests of Northern and Southern Vietnam. The bark and root of this plant have been used in traditional medicine to treat leprosy and contraception. Besides that the leaves are used by coastal residents to drive mosquitoes away 1 2 . Previous phytochemical studies on A. marina have demonstrated the presence of iridoid glucosides 3 4 phenylpropanoid glycosides abietane diterpenoid glucosides lignan glycosides 5 and flavonoids 6 . In this article we report the isolation and structural .
