Pulp of buriti palms (Mauritia flexuosa L.f.) from two Brazilian regions had their phenolic and carotenoid contents and antioxidant capacity evaluated through different methods (ABTS, DPPH, FRAP and ORAC). Buriti pulp from the Cerrado presented higher phenolic levels (435.08 mg AGE 100 g(-1)) and elevated antioxidant capacity in all tests. The fruits from the Amazon region had a higher total carotenoid content (52.86 mg 100 g(-1)). Carotenoid profile has confirmed β-carotene predominance in both regions studied. The buritis' region of origin influenced bioactive compound contents and antioxidant capacity of the fruits analyzed. A significant positive correlation (r ⩽ 0.95; p<0.05) was observed between total phenolics and antioxidant capacity through the different methods applied. Results showed promising prospects for the future exploitation of buriti fruits as a potential source of carotenoids and natural antioxidants.
通过不同方法（ABTS、DPPH、FRAP和ORAC）对来自巴西两个地区的毛里求斯棕榈（Mauritia flexuosa L.f.）果肉的酚类和类胡萝卜素含量以及抗氧化能力进行了评估。塞拉多地区的毛里求斯棕榈果肉呈现出更高的酚类水平（435.08毫克没食子酸当量/100克），并且在所有测试中抗氧化能力都有所提高。亚马逊地区的果实总类胡萝卜素含量更高（52.86毫克/100克）。类胡萝卜素谱证实了在所研究的两个地区中β-胡萝卜素占主导地位。毛里求斯棕榈的原产地区影响了所分析果实的生物活性化合物含量和抗氧化能力。通过应用的不同方法观察到总酚类与抗氧化能力之间存在显著正相关（r⩽0.95；p<0.05）。结果表明，未来将毛里求斯棕榈果实作为类胡萝卜素和天然抗氧化剂的潜在来源进行开发具有广阔前景。
