title: Iridoids from Avicennia marina.
abstract: Three new iridoid glucosides, 10-O-[(E)-cinnamoyl]-geniposidic acid, 10-O-[(E)-p-coumaroyl]-geniposidic acid, 10-O-[(E)-caffeoyl]-geniposidic acid and the known iridoid glucoside, 2'-O-[(E)-cinnamoyl]-mussaenosidic acid have been isolated from Avicennia marina. The structures were determined primarily by NMR spectroscopy. The assignment of NMR signals was performed by means of 1H-1H COSY, HMQC and HMBC experiments.
