Oxygen 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 کاملIridoids 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 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 th...

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...
