Abstract: | Avicennia officinalis L., Avicenniaceae, is a widespread plant in mangrove forests in Vietnam, Cambodia, Thailand, Indonesia,... A. officinalis's chemical compositions remain mostly unknown, Therefore, we now report on the structural elucidation of six compounds isolated from this plant growing in Can Gio mangrove forest in Ho Chi Minh City by using a variety of chromatographic techniques. The structures of these compounds were elucidated by NMR spectroscopy analysis as well as compared with data in the literature. They areaviridoid(1), (lS,5R,8S,9R)-2'-(E-couimroyl) mussaenosidic acid (2), velutin (3), a-tocopherol (4), and a mixture of 6-methoxynaphtho[2,3-b]-furan-4,9-quinone (5) and 7-methoxynaphtho[2,3-b]-furan-4,9-quinone (6). To the best of our knowledge, (1) is a new compound while (2), (4), (5) and (6) are obtained from Avicennia genus for the first time, Further studies on this species are in progress. |
