Polysaccharide with antioxidant, α-amylase inhibitory and ACE inhibitory activities from Momordica charantia.
Functional polysaccharide was isolated from Momordica charantia, with a yield of 36% (w/w). M. charantia bioactive polysaccharide (MCBP) was an acidic and branched heteropolysaccharide with a molecular weight of 92 kDa. Fourier transform infrared spectroscopic analysis indicated that MCBP was a pectin-like polysaccharide with an esterification degree of 53% and it contains numerous monosacchari...
متن کاملα-Amylase inhibitory property, antioxidant activity and toxicological study of Salvia chloroleuca
Background and objectives: Salvia chloroleuca Rech. f. & Allen., is an endemic species growing wildly in north east and center parts of Iran but there is no information about its safety. To provide information about the safety of the species, we evaluated its acute and sub chronic toxicity in rats. Methods: In acute toxicity study, the aqueous methanol (80%) extract at a single dose of...
متن کامل?-Amylase Inhibitory Activities of Six Salvia Species
?-Amylase inhibitory activities of ethanol extracts from six selected Iranian Salvia species (S. hydrangea DC., S. hypoleuca Benth., S. officinalis L., S. reuterana Boiss., S. verticillata L. and S. virgata Jacq.) were examined, using in vitro model. In addition, antioxidant capacities (DPPH• radical scavenging) and total flavonoid cotents of the extracts were also determined. The results showe...

متن کاملAntioxidant Activity and α-Glucosidase Inhibitory Activities of the Polycondensate of Catechin with Glyoxylic Acid
In order to investigate polymeric flavonoids, the polycondensate of catechin with glyoxylic acid (PCG) was prepared and its chemically antioxidant, cellular antioxidant (CAA) and α-glucosidase inhibitory activities were evaluated. The DPPH and ABTS radical scavenging activities and antiproliferative effect of PCG were lower than those of catechin, while PCG had higher CAA activity than catechin...
