Amamou, Sawsen published the artcileEffect of extraction condition on the antioxidant, antiglycation and α-amylase inhibitory activities of Opuntia macrorhiza fruit peels polysaccharides, Synthetic Route of 59-23-4, the main research area is Opuntia fruit peel polysaccharide antioxidant antiglycation alpha amylase.
In this study, the effect of acidic, neutral and alk. medium extraction of polysaccharides from Opuntia macrorhiza fruit peels was evaluated. The extraction yields ranged from 6.8 to 13.7%, and the highest content in uronic acid was observed in the acidic extract (50.5%). Likewise, Fourier transform IR (FT-IR) spectroscopy showed the presence of uronic acids in the Me ester and free forms, with a degree of esterification of 46.9, 39.3 and 48.3% for the acidic, neutral and alk. extracts Monosaccharide composition showed that the extracted polysaccharides were principally composed of arabinose, rhamnose, galactose and glucose, with an average mol. weight of 208,000, 1460,000 and 1380,000 g/mol, resp. Therefore, this finding indicates that extracts are a low methoxyl pectic polysaccharides. Finally, all polysaccharides exhibited good antioxidant activity, especially acid extract significantly inhibits lipid peroxidation and in vitro protein glycation in BSA-glucose glycation model and alk. extract inhibits α-amylase with a competitive type.
