Bioactive Compounds and Antioxidant Activity of Bunchosia glandulifera

Bunchosia glandulifera is a red-colored fruit and a source of bioactive compounds with antioxidant potential. The fruit was collected in the city of Santo Antonio Patrulha-Brazil, and the pulp contained phenolic compounds, anthocyanins, flavonoids, lycopene, -carotene, vitamin C, and caffeine. Rutin, vitexin, and quercitrin were the phenolic compounds identified in the pulp. The concentrations of lycopene (16.39 mg/100 g fruit) and -carotene (8.10 mg/100 g fruit) provided the fruit's distinct color. The fruit pulp was rich in caffeine (206.35 mg/100 g) and showed antioxidant activity as determined by Ferric Reducing Antioxidant Power, 2,2-Azinobis-(3-Ethylbenzothiazoline-6-Sulfonic acid, and 2,2 Difenil-1-Picrilhidrazil. The high antioxidant activity was due to its high levels of bioactive compounds.
