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...

Evaluation of antioxidant activity in fruit extracts of Avicennia Marina L and Avicennia Officinalis L

Antioxidant activity of Avicenni marina L and Avicennia officinalis L fruit extracts in ethyl acetate, acetone, methanol and ethanol were studied by ABTS, CrO5 and FRAP method. All the extracts possessed significant amount of the antioxidant activity, extracts in methanol and ethanol was demonstrated convincingly higher antioxidant activity by all the three methods. Whereas, the ethyl acetate e...

ANTIBACTERIAL 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...

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 ...
