Structural characterization and antioxidant activities of polysaccharides from okra (Abelmoschus esculentus (L.) Moench) pericarp

In this study, okra (Abelmoschus esculentus (Linn.) Moench) pods (pericarp) obtained after removing seeds and flesh were applied for polysaccharide extraction. The 60 °C water extract polysaccharide (OPW-60) was obtained from okra peel at 60 °C, and then 100 °C water extract polysaccharide (OPW-100) was obtained from the residue at 100 °C. Acid extraction at 60 °C was finally used to obtain the polysaccharide by acid leaching at 60 °C (OPA-60)....
