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 کاملEvaluation 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...
متن کاملHydroxylamine Inhibition of Xanthine Oxidase
In the course of investigations regarding the effects of various chemical agents on neoplast,ic purine metabolism, it was observed that hydroxylamine prevents the accumulation of uric acid or allantoin that normally occurs upon incubation of crude tissue homogenates. Subsequent studies, reported in this paper, demonstrate that hydroxylamine is a competitive inhibitor of xanthine oxidase activit...
متن کاملInhibition of xanthine oxidase activity by gnaphalium affine extract.
OBJECTIVE To evaluate the inhibitory effect of Gnaphalium affine extracts on xanthine oxidase (XO) activity in vitro and to analyze the mechanism of this effect. METHODS In this in vitro study, Kinetic measurements were performed in 4 different inhibitor concentrations and 5 different xanthine concentrations (60, 100, 200, 300, 400 Μmol/L). Dixon and Lineweaver-Burk plot analysis were used to...
