Fifteen fruits commonly used by the ethnic population in Nepal were studied for the antioxidant activity and total polyphenol content (TPC). Among them, Terminalia bellirica, Terminalia chebula, Phyllanthus emblica and Spondias pinnata were the most potent antioxidants as compared with vitamin C based on the 1,1-diphenyl-2-picryl hydrazyl radical assay. These fruits also contained high TPCs. Spondias pinnata, Pyrularia edulis, Melastoma malabathricum, Cipadema bacifera and Choerospondias axillaries fruits were evaluated for the first time. Moreover, Spondias pinnata was found to be more potent (16% radical scavenging activity at 5 microg/ml) than vitamin C (5% radical scavenging activity at 5 microg/ml). Antioxidant activity showed correlation to TPC with the correlation coefficients (R(2)) as 0.7189 and 0.7246 for the methanol and water extracts, respectively. This study suggests that a number of these fruits may have the potential to confer beneficial health effects due to their antioxidant activity and TPC.
对尼泊尔少数民族常用的 15 种水果的抗氧化活性和总多酚含量（TPC）进行了研究。根据 1,1-二苯基-2-苦基肼自由基测定法，与维生素 C 相比，诃子、余甘子、余甘子和斯潘迪亚斯 pinnata 是最有效的抗氧化剂。这些水果还含有高 TPC。首次对斯潘迪亚斯 pinnata、Pyrularia edulis、Melastoma malabathricum、Cipadema bacifera 和 Choerospondias axillaries 进行了评估。此外，斯潘迪亚斯 pinnata 的活性（在 5μg/ml 时的自由基清除活性为 16%）比维生素 C（在 5μg/ml 时的自由基清除活性为 5%）更强。抗氧化活性与 TPC 呈正相关，甲醇和水提取物的相关系数（R（2））分别为 0.7189 和 0.7246。本研究表明，由于这些水果具有抗氧化活性和 TPC，其中一些可能具有带来有益健康效果的潜力。
