Foods provide essential and bioactive compounds with health-promoting properties such as antioxidant, anti-inflammatory, and hypocholesterolemic activities, which have been related to vitamins A, C, and E and phenolic compounds such as flavonoids. Therefore, the aim of this work was to identify potential sources of bioactive compounds through the determination of flavonoids and ellagic acid contents and the in vitro antioxidant capacity and alpha-glucosidase and alpha-amylase inhibitory activities of Brazilian native fruits and commercial frozen pulps. Camu-camu, cambuci, uxi, and tucuma and commercial frozen pulps of cambuci, cagaita, coquinho azedo, and araca presented the highest antioxidant capacities. Cambuci and cagaita exhibited the highest alpha-glucosidase and alpha-amylase inhibitory activities. Quercetin and kaempferol derivatives were the main flavonoids present in most of the samples. Ellagic acid was detected only in umbu, camu-camu, cagaita, araca, and cambuci. According to the results, native Brazilian fruits can be considered as excellent sources of bioactive compounds.
食物提供了具有抗氧化、抗炎和降胆固醇作用等促进健康特性的必需和生物活性化合物，这些特性与维生素 A、C 和 E 以及类黄酮等酚类化合物有关。因此，本工作的目的是通过测定巴西本地水果和商业冷冻果泥中的类黄酮和鞣花酸含量以及体外抗氧化能力和α-葡萄糖苷酶和α-淀粉酶抑制活性来确定生物活性化合物的潜在来源。卡姆果、坎布希、乌希、图库玛和商业冷冻果泥中的坎布希、卡加伊塔、科奎尼奥·阿泽多和阿卡拉具有最高的抗氧化能力。坎布希和卡加伊塔表现出最高的α-葡萄糖苷酶和α-淀粉酶抑制活性。大多数样品中都存在槲皮素和山奈酚衍生物等主要类黄酮。只有余甘子、卡姆果、卡加伊塔、阿卡拉和坎布希中检测到鞣花酸。根据结果，巴西本地水果可被视为生物活性化合物的极好来源。
