Iridoids from Avicennia marina.
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 ...
متن کاملNew Antioxidative Secondary Metabolites from the Fruits of a Beibu Gulf Mangrove, Avicennia marina
Further chemical investigation of the fruits of the mangrove, Avicennia marina, afforded three new phenylethyl glycosides, marinoids J-L (1-3), and a new cinnamoyl glycoside, marinoid M (4). The structures of isolates were elucidated on the basis of extensive spectroscopic analysis and by comparison of the data with those of related secondary metabolites. The antioxidant activity of the isolate...
متن کاملFour New Jacaranone Analogs from the Fruits of a Beibu Gulf Mangrove Avicennia marina
Four new jacaranone analogs, marinoids F-I (1-4), were isolated from the fruits of a Beibu Gulf mangrove Avicennia marina. The structures were elucidated based on analysis of spectroscopic data. Marinoids F and G are shown to be diastereoisomers of chlorocornoside, a new halogen containing marine secondary metabolite. The antioxidant activity of the isolates was evaluated using a cellular antio...
متن کاملBiosynthesis of Titanium Dioxide Nanoparticles from the Mangrove (Avicennia marina) and Investigation of its Antibacterial Activity
Background and purpose: Development of biocompatible and nontoxic methods for synthesis of nanoparticles is important in bio-nanotechnology. This study aimed at biosynthesis of titanium dioxide nanoparticles (TiO2 NPs) using leaf of the native mangrove (Avicennia marina) and investigating its antibacterial activity. Materials and methods: Effect of four different solutions composed of dry extr...
متن کاملOxygen microgradients in the rhizosphere of the mangrove Avicennia marina
Oxygen concentration was measured in aerial roots (pneumatophores), horizontal cable roots and surrounding sediment of the tree Avicennia marina (Forsk.) Vierh. in a mangrove swamp at Ao Nam Bor, on the southeast coast of Phuket Island, Thailand. The O2 measurements were made in the field with a polarographlc oxygen minielectrode. The O2 concentration inside pneurnatophores was 63 to 88 % of ai...
