title: Maesa indica: a nutritional wild berry rich in polyphenols with special attention to radical scavenging and inhibition of key enzymes,α-amylase andα-glucosidase.
abstract: The present study was aimed to evaluate the nutritional, antioxidant properties and inhibition of the key enzyme such asα-amylase andα-glucosidase from the fruits ofMaesa indica. The results revealed thatM. indicafruits possess an enormous amount of protein (45.68 mg/g), carbohydrates (25.12 mg/g) and mineral elements. The acetone extract were capable of hunting radicals by providing electrons and break chain reaction, especially in ABTS·+(3719.23 µmol TE/g extract), OH·(66.50 %) and NO·(81.50 %) radical scavenging assays. The methanol extract showed a strong inhibition towardsα-amylase andα-glucosidase (IC50of 37.80 and 23.74 µg/mL, respectively). HPLC analysis enumerate that both extracts illustrates the presence of polyphenolic compounds namely quercetin, caffeic acid, rutin and chlorogenic acid.
