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 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 کاملInverse relationship between salinity and n-alkane dD values in the mangrove Avicennia marina
Hydrogen isotope ratios in lipids derived frommangroves have the potential to be used for paleohydrologic reconstructions and could serve as a much needed tool for establishing past climate variability in the tropics. We assessed the effect of salinity on the apparent fractionation factor, aa, between mangrove derived n-alkanes and their source water for Avicennia marina (gray mangrove) specime...
متن کاملANTIBACTERIAL AND SYNERGISTIC ACTIVITY OF MANGROVE (Avicennia marina) EXTRACTS ON ESBL AND MBL PRODUCING UROPATHOGENS
Growing incidences of β-lactamase producing uropathogens have been observed worldwide. Extended Spectrum β-lactamase (ESBLs) and Metallo β-lactamase (MBLs) are two types of β-lactamases that have emerged as a major threat with limited treatment options. In the current study, the effect of Avicennia marina leaf and stem extracts was studied on 10 ESBL and 10 MBL producing uropathogens which were...
