Abstract
|
|
|
This study compared the estimated glycemic index, antioxidant, and ¥á-amylase and ¥á-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 ¥á-amylase and ¥á-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 ¥á-glucosidase and ¥á-amylase activities.
