为筛选具有较高营养价值的野生水果，对56种华南野生水果的抗氧化活性进行了系统评价。脂溶性成分用四氢呋喃提取，水溶性成分用50：3.7：46.3（v/v）甲醇-乙酸-水混合物提取。采用三价铁还原抗氧化能力（FRAP）和Trolox等效抗氧化能力（TEAC）测定法评价提取物的抗氧化能力，并采用Folin-Ciocalteu法测定其总酚含量。这些野生水果中的大多数是第一次分析其抗氧化活性。总体而言，这些水果具有较高的抗氧化能力和总酚含量。FRAP值和TEAC值之间的显着相关性表明，这些野生水果中的抗氧化成分能够减少氧化剂和清除自由基。抗氧化能力和总酚含量之间的高度相关性表明，酚类化合物可能是测得的抗氧化活性的主要贡献者。结果表明，大叶桉、亮叶桉、血红木、白千层、紫薇、缓心丁香、大花紫薇和大头茶果实的抗氧化能力和总酚含量最高，可作为天然抗氧化剂和功能性食品的丰富来源。研究结果对充分利用这些野生果实具有重要意义。
In order to identify wild fruits possessing high nutraceutical potential, the antioxidant activities of 56 wild fruits from South China were systematically evaluated. The fat-soluble components were extracted with tetrahydrofuran, and the water-soluble ones were extracted with a 50:3.7:46.3 (v/v) methanol-acetic acid-water mixture. The antioxidant capacities of the extracts were evaluated using the ferric reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) assays, and their total phenolic contents were measured by the Folin–Ciocalteu method. Most of these wild fruits were analyzed for the first time for their antioxidant activities. Generally, these fruits had high antioxidant capacities and total phenolic contents. A significant correlation between the FRAP value and the TEAC value suggested that antioxidant components in these wild fruits were capable of reducing oxidants and scavenging free radicals. A high correlation between antioxidant capacity and total phenolic content indicated that phenolic compounds could be the main contributors to the measured antioxidant activity. The results showed that fruits of Eucalyptus robusta, Eurya nitida, Melastoma sanguineum, Melaleuca leucadendron, Lagerstroemia indica, Caryota mitis, Lagerstroemia speciosa and Gordonia axillaris possessed the highest antioxidant capacities and total phenolic contents among those tested, and could be potential rich sources of natural antioxidants and functional foods. The results obtained are very helpful for the full utilization of these wild fruits.
