摘要
A chemical examination of the mangrove plant Avicennia marina (Forrsk.) Vierh resulted in the isolation and characterization of five new iricloids, marinoids A-E (1-5), along with 2'-cinnamoyl-mussaenosidic acid (6), 2'-O-(4"-methoxycinnamoyl) mussaenosidic acid (7),2'-O-(4"-hydroxycinnamoyl) mussaenosidic acid (8), and 3(R)-hydroxy-5-phenyl-4(E)-pentenoic acid (9). The structures of 1-5 were elucidated on the basis of 1 D and 2D NMR (COSY, HMQC, HMBC, and NOESY) in association with IR and MS data analysis. Copyright (C) 2008 John Wiley & Sons, Ltd.
