Total polyphenol content and antioxidant activities of non-edible parts (seed and peel) of eight tropical fruits were analyzed and compared with those of their edible parts. The antioxidant activity was evaluated based on the ability of the fruit extracts (seed, peel and pulp) to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radicals, and the ferrous ion-chelating capacity. Total polyphenol content in seed, peel and pulp ranged from 0.2 to 153, 5.0 to 124, and 1.0 to 12 mg/g DW, respectively. Non-edible parts of the tropical fruits were found to have significant antioxidant activities. Among them, mango seed, mango peel, starfruit peel and avocado peel showed higher antioxidant potential by the DPPH and ABTS radical scavenging assays. The DPPH and ABTS radical scavenging abilities were highly correlated with total polyphenol content. Kiwano and papaya peels showed strong ferrous ion-chelating capacity, although they did not have high polyphenol content and DPPH and ABTS radical scavenging activities.

某些热带水果非食用部分的抗氧化能力评估
分析了八个热带水果不可食用部分(种子和果皮)的总多酚含量和抗氧化活性,并将其与可食用部分进行比较。根据水果提取物(种子,果皮和果肉)清除2,2-二苯基-1-吡啶并肼基(DPPH)和2,2'-叠氮基双(3-乙基苯并噻唑啉-6-的能力)评估其抗氧化活性。磺酸(ABTS)自由基和亚铁离子的螯合能力。种子,果皮和果肉中的总多酚含量分别为0.2至153、5.0至124和1.0至12 mg / g DW。发现热带水果的非食用部分具有显着的抗氧化活性。其中,通过DPPH和ABTS自由基清除测定,芒果种子,芒果皮,杨桃皮和鳄梨皮显示出更高的抗氧化潜能。DPPH和ABTS自由基清除能力与总多酚含量高度相关。Kiwano和木瓜皮显示出较强的亚铁离子螯合能力,尽管它们不具有较高的多酚含量以及DPPH和ABTS自由基清除活性。
