Phytochemical composition and antioxidant potential of different varieties viz. Flor Branca, Costa Rica and Junco of green unripe acerola (Malphigia emarginata D.C.) fruits

Malpighia emarginata D.C is an important crop of Brazil and significant source antioxidant active compounds with notable health effects. The purpose this work was to study three varieties acerola (Malpighia D.C) at green unripe stage maturity from the São Francisco Valley Northeast Brazil. fruits were evaluated for physico-chemical composition, bioactive compounds, through spectrophotometric analysis liquid chromatography, as well profile macro micro minerals capacity. presented satisfactory results in quality parameters. HPLC-DAD phenolic identified kaempferol-3-glucoside (32.68 mg/100 g), p-coumaric acid (28.87 g) isorhamnetin (11.41 major mainly variety Flor Branca (FB). obtained profiles sugars organic acids similar among varieties. excellent sources elements K, Ca, Mg Mn. Moreover, FB represents higher capacity ABTS?+ (8613.54 ?M Trolox/g) ORAC (2454.42 Trolox/g). Thus, show potential be applied selection utilization programs based on their specific nutritive characters, contributing development new products.
