对香港13种食用和药用果树的22个样品(包括水果、果肉、果皮和种子)的抗氧化能力、营养品质和酚类物质进行了研究。所有抗氧化剂和营养参数在供试样品之间存在显著差异。原花青素、黄酮类和酚酸类化合物是这些样品中的主要酚类化合物。香港大头茶全果具有最强的抗氧化能力(213.4 mmoltrolox/100g干重)，类胡萝卜素含量次之。番荔枝种子中蛋白质、脂肪和氨基酸的含量最高，分别为17.6%、37.2%和14.4%。大多数果皮和一些种子含有高水平的酚类物质、类胡萝卜素和维生素C，这有助于它们具有很强的抗氧化活性。这些香港植物的一些果实、果皮或种子可以作为功能成分和营养食品的潜在来源。(C)2010 Elsevier Inc.保留所有权利。
Twenty-two samples (including fruits, pulp, peel, or seeds) from 13 edible and medicinal fruit plant species selected in Hong Kong were investigated for their antioxidant capacity, nutritional quality and phenolic profiles. Significant variation existed among the tested samples in all the antioxidant and nutritional parameters. Proanthocyanidins, flavonoids and phenolic acids were identified as major categories of phenolic compounds in these samples. Whole fruits of Hong Kong gordonia exhibited the strongest antioxidant capacity (213.4 mmol trolox/100 g DW) and had the second highest content of carotenoids. Seeds of Annona squamosa possessed the highest contents of total protein, fat and amino acids (17.6, 37.2 and 14.4%, respectively). Most peel and some seeds contained high levels of phenolics, carotenoids and vitamin C, which contributed to their strong antioxidant activity. Some of the fruits, peel or seeds from these Hong Kong plants can be a potential resource of functional components and nutraceuticals. (C) 2010 Elsevier Inc. All rights reserved.
