Abstract:
In this study, phenolic compounds from Actinidia macrosperma kiwifruit
were extracted in to different extraction solvents namely 70% aqueous acetone, 80% aqueous methanol, 80% aqueous ethanol, 100% methanol and water. Total phenolic, total flavonoid contents as well as total flavanol content of the extracts were assessed spectrometrically. Among the solvents employed, 70% aqueous acetone resulted in the highest values of total phenolic (823.1±14.4 mg gallic acid equivalent/ 100 g DW), total flavonoid (170.9±1.9 mg catechin equivalent/ 100 g DW), and total flavanol (82.6±0.6 mg catechin equivalent/ 100 g DW) contents. It is concluded that 70%
aqueous acetone extract from A. macrosperma kiwifruit contains many
flavonoids which can be isolated and identified in the future studies and selected as the best extraction medium for this fruit.
