The aim of this work was to evaluate the main nutrients and their antioxidant properties of a Chinese wild edible fruit, , collected from the ecoregion of Hainan province, China. The analytical results revealed that fruits were rich in amino acids (1097 mg/100 g in total), minerals (595.75 mg/100 g in total), and unsaturated fatty acids (74.18 g/100 g in total fat). The lyophilized powder of edible portion contained the higher polyphenols content than the inedible portion powder. The UPLC-Q-TOF-MS analysis of the extractable and non-extractable phenolics indicated the presence of 65 compounds including 39 free phenolics, 14 insoluble-glycoside-phenolics, and 22 insoluble-ester-phenolics. In addition, the non-extractable phenolics obtained by alkali hydrolysis showed significant antioxidant activities by/through DPPH and ABTS radical scavenging. These findings of fruits, for the first time, suggest that these polyphenol-rich fruits may have potential nutraceutical efficacies.
本研究旨在评估一种中国野生食用水果——，其来源于中国海南省的生态区，的主要营养成分及其抗氧化特性。分析结果表明，该水果富含氨基酸（总含量为 1097mg/100g）、矿物质（总含量为 595.75mg/100g）和不饱和脂肪酸（总脂肪含量为 74.18g/100g）。冻干的可食用部分粉末比不可食用部分粉末含有更高的多酚含量。可提取和不可提取酚类物质的 UPLC-Q-TOF-MS 分析表明，存在 65 种化合物，包括 39 种游离酚类、14 种不溶性糖苷酚类和 22 种不溶性酯类酚类。此外，通过碱水解得到的不可提取酚类物质通过 DPPH 和 ABTS 自由基清除表现出显著的抗氧化活性。这些关于 的研究结果首次表明，这些富含多酚的水果可能具有潜在的营养功效。
