Citrus ×clementina juice obtained from fruits collected in three different areas(flood plain, hill and coastal plain) was investigated for the chemical composition, radical scavenging properties (DPPH and ABTS tests), andα-amylase andα-glucosidase inhibitoryactivity. Neohesperidin (72.96-116.50 mg/100 mL), hesperidin (55.24-69.52 mg/100 mL) and narirutin (7.21-12.13 mg/100 mL) are the main flavonoids identified by HPLC analyses.In carbohydrate-hydrolysing enzymes inhibitory activity tests, samples showed higherpotency againstα-glucosidase. Juice from hill was the most active with an IC50 value of 77.79µg/mL.Data on the radical scavenging activity revealed the following trend of potency flood plain >coastal plain > hill. These results could help farmers to select fruits for different industrialpurpose such as functional food and matrix to extract nutraceutical products.

Abstract

Citrus ×clementina juice obtained from fruits collected in three different areas(flood plain, hill and coastal plain) was investigated for the chemical composition, radical scavenging properties (DPPH and ABTS tests), andα-amylase andα-glucosidase inhibitoryactivity. Neohesperidin (72.96-116.50 mg/100 mL), hesperidin (55.24-69.52 mg/100 mL) and narirutin (7.21-12.13 mg/100 mL) are the main flavonoids identified by HPLC analyses.In carbohydrate-hydrolysing enzymes inhibitory activity tests, samples showed higherpotency againstα-glucosidase. Juice from hill was the most active with an IC50 value of 77.79µg/mL.Data on the radical scavenging activity revealed the following trend of potency flood plain >coastal plain > hill. These results could help farmers to select fruits for different industrialpurpose such as functional food and matrix to extract nutraceutical products.
