Bioactive compounds and antioxidant activity three fruit species from the Brazilian Cerrado

Abstract The aim of this study was to determine the content of bioactive compounds and antioxidant activity present in three fruit species from the Brazilian Cerrado: carnauba (Copernicia prunifera (Mill.) H.E. Moore), murici (Byrsonima crassifolia L. Rich)and oiti (Licania tomentosa (Benth) Fritsch). Among analyzed fruits, oiti showed the highest total phenolic content (1236.42 ± 34.06 mg GAE 100 g-1) followed by murici (468.90 ± 27.30 mg GAE 100 g-1) and carnauba (314.44 ± 9.50 mg GAE 100 g-1). Regarding the antioxidant activity, murici showed 4350.31 ± 1.85 µmol TEAC.100 g-1 and oiti showed 14721.69 ± 0.85 µmol TEAC.100 g-1. In addition, high content of anthocyanins was verified in carnauba (9.35 ± 0.00 mg-cy-3-glu.100 g-1), as well as carotenoids (20.0 ± 1.23 mg-ß-carot.100 g-1) and vitamin C (58.60 ± 1.32 mg.100 g-1) in murici. In conclusion, data obtained add valuable information to the current knowledge on the nutritional and functional features of fruits from the Brazilian Cerrado that have been scarcely explored, such as those analyzed, which showed high content of bioactive compounds and antioxidant activity.

摘要 本研究旨在测定源自巴西塞拉多（Brazilian Cerrado）的三种水果的生物活性物质含量与抗氧化活性：巴西棕榈蜡树果（carnauba，*Copernicia prunifera* (Mill.) H.E. Moore）、穆里西果（murici，*Byrsonima crassifolia* L. Rich）以及奥伊蒂果（oiti，*Licania tomentosa* (Benth) Fritsch）。在所分析的水果中，奥伊蒂果的总酚类物质含量最高，为1236.42 ± 34.06 mg 没食子酸当量（Gallic Acid Equivalent, GAE）·100 g⁻¹，其次为穆里西果（468.90 ± 27.30 mg GAE·100 g⁻¹）与巴西棕榈蜡树果（314.44 ± 9.50 mg GAE·100 g⁻¹）。就抗氧化活性而言，穆里西果的抗氧化活性为4350.31 ± 1.85 µmol Trolox当量抗氧化能力（Trolox Equivalent Antioxidant Capacity, TEAC）·100 g⁻¹，奥伊蒂果则为14721.69 ± 0.85 µmol TEAC·100 g⁻¹。此外，巴西棕榈蜡树果中检测到高含量的花青素（9.35 ± 0.00 mg 矢车菊素-3-葡萄糖苷（cyanidin-3-glucoside, cy-3-glu）·100 g⁻¹），而穆里西果则含有高含量的类胡萝卜素（20.0 ± 1.23 mg β-胡萝卜素（beta-carotene, ß-carot）·100 g⁻¹）与维生素C（58.60 ± 1.32 mg·100 g⁻¹）。综上，本研究所得数据为当前关于巴西塞拉多地区鲜少被探索的水果的营养与功能特性的认知补充了宝贵信息，本次分析的三种水果均表现出较高的生物活性物质含量与抗氧化活性。
