Abstract
|
|
|
|
This study compared the estimated glycemic index, antioxidant, and α-amylase and α-glucosidase inhibitory properties of ripe Citrus paradisi fruit’s parts, as well as their phenolic composition by employing high performance liquid chromatography fixed with diode array detector. The result revealed that C. paradisi fruit’s peel exhibited significantly lowest glycemic index, highest antioxidant and inhibitory effects on the activities of α-amylase and α-glucosidase, with concomitant highest polyphenol constituents compared to other parts of the fruit. Thus, being a waste product of the fruit, it could be a prospective source of natural products for functional food development, nutraceuticals or dietary supplement for the management of diabetes, due to the low glycemic index, antioxidant and inhibition of α-glucosidase and α-amylase activities.
