Bioactive compounds and antioxidant activity of Ximenia americana coming from different collection sites
The study aimed to evaluate the bioactive compounds and antioxidant activity of edible fraction (pulp and peel) in green and ripe ripening stages of the fruit and the seed of wild plum (Ximenia americana L.) from different production sites of occurrence in the semiarid region of Brazil. To characterize the edible fraction, the experiment was conducted in a completely randomized design in a factorial 3 x 2, where the first factor was the collection sites and the second factor the maturation stages, with 4 repetitions with 25 fruits each. As for seeds the experiment was conducted in a completely randomized design with 4 repetitions, totaling 25 seeds per experimental plot. The fruits were collected in the communities of Mulunguzinho, Pau Branco and Mata do Meio in the county of Mossoró, RN, Brazil. The edible fraction of the fruit Ximenia americana contains high levels of vitamin C (160,26 mg/100 g), yellow flavonoids (43,12 mg/100 g), total extractable polyphenols (3066,48 mg/100 g) and antioxidant activity (365,55 g fruit/g DPPH e 251,70 μmol Trolox/g) and the seeds contain content of polyphenols (2067,56 mg/100 g) and antioxidant (373,80 g fruit/g DPPH e 279,96 251,70 μmol Trolox/g). The edible part of the green fruit contains higher content of total extractable polyphenols, total carotenoids, yellow flavonoids and total anthocyanins. The edible portion of the fruits and the seeds from the community of Pau Branco contains the lowest content of total extractable polyphenols and antioxidant activity.
