Abstract

Aqueous and acetone extracts from 15 fruits have been screened for antioxidant activity using DPPH method and s-carotene/linoleic acid model. All fruits studied showed antioxidant activity, but in different extent. Acerola, cashew-apple, papaya "formosa", papaya "solo", orange and guava showed the higher antioxidant activity (>;70%) in DPPH method, followed by pineapple, bergamont, mango "rosa", melon "reticulares", melon "inodorus", melon "orange flesh" and sugar-apple aqueous extract (moderate, 60-70%) and mango "espada" and watermelon aqueous extract, the lowest activity. Acerola, cashew-apple, sugar-apple and guava acetone extracts exhibited higher scavenging activity toward DPPH radicals (>;70%).β-carotene/linoleic acid model index of sugar-apple aqueous extract and guava acetone extract demonstrated moderate antioxidant activity (60-70%), meanwhile acerola aqueous extract and papaya "formosa" acetone extract the lower. According to antioxidant activity, fruits can be indicated as natural antioxidants sources, pointing out acerola, cashew-apple, papaya "solo", papaya "formosa", guava, orange and sugar-apple as the highest in antioxidant capacity.

采用DPPH法和s-胡萝卜素/亚油酸模型对15种水果的水提物和丙酮提物的抗氧化活性进行了筛选。所有水果均表现出抗氧化活性，但程度不同。DPPH法抗氧化活性最高的是针叶、苹果、番木瓜“福尔摩沙”、番木瓜“solo”、橙子和番石榴(> 70%)，其次是菠萝、佛手柑、芒果“rosa”、甜瓜“reticulares”、甜瓜“inodorus”、甜瓜“orange果肉”和糖苹果水提液(中等，60-70%)，活性最低的是芒果“espada”和西瓜水提液。针叶、腰果、糖苹果和番石榴丙酮提取物对DPPH自由基的清除活性较高(> 70%)。糖苹果水提物和番石榴丙酮提取物的β-胡萝卜素/亚油酸模型指数为中等抗氧化活性(60 ~ 70%)，针叶花水提物和木瓜“福尔摩沙”丙酮提取物的抗氧化活性较低。根据抗氧化活性，水果可以被认为是天然抗氧化剂的来源，指出针叶果、腰果苹果、木瓜“独奏”、木瓜“福尔摩沙”、番石榴、橙子和糖苹果的抗氧化能力最高。
