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 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...
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 کاملPb and Cd accumulation in Avicennia marina from Qeshm Island,
The accumulation of heavy metals Pb and Cd in the mangrove, Avicennia marina, was studied on the southern coast of Iran, particularly on and near Qeshm Island in the Persian Gulf. The samples were collected from 7 stations which they were analyzed by flame Atomic absorption spectrophotometer after chemical digestion. Maximum Pb and Cd in leaves are (34.50, 3.52 ppm) and minimum of them are in ...
