Description
Summary:[Display omitted] •24 phenolic compounds were identified in P. leschenaultii fruit for the first time.•Volatile profile reveals 67 volatile compounds including alcohols and esters.•High levels of protein and good quality of amino acids were detected in fruits.•Fruit pulp serves as potent inhibitor of α-amylase and α-glucosidase activities. Twenty-four phenolic compounds including daidzein, epicatechin and artepillin C were identified in Passiflora leschenaultii DC. fruit by UHPLC-QqQ-MS/MS analysis. The aroma profile has been studied using the HS–SPME/GC–MS which revealed 67 volatile compounds including 13 terpenes, 18 alcoholics, 15 esters, ketones and phenolic acids. Further, the proximate composition, anti-radical and anti-diabetic activities of fruit pulp were also determined. The fresh fruit pulp of P. leschenaultii registered higher total phenolic (691.90 mg GAE/g extract) and tannin (313.81 mg GAE/g extract) contents and it also exhibited maximum DPPH (IC50 of 6.69 µg/ml) and ABTS+ (9760.44 µM trolox equivalent/g extract) scavenging activities. The fresh fruit pulp showed a strong inhibition towards the α-Amylase and α-Glucosidase (IC50 of 32.20 and 19.81 µg/mL, respectively) enzymes. Thus, the work stipulates that phenolic compounds rich P. leschenaultii fruit can serve as a potential nutraceutical, antioxidative and anti-diabetic agent in food and pharmaceutical formulations.
