测定了柠檬、橙子和葡萄柚的抗氧化活性 (总自由基吸收抗氧化潜力 ,TRAP)。也测定了食用纤维、抗坏血酸、微量元素、总多酚和必需酚的含量。发现果皮所含纤维的量比已剥皮果的要高得多 ( P0 .0 5) ,但是不同水果的果皮或不同水果的已剥皮样品之间的纤维含量没有显著的差别。柠 The antioxidant activity of lemon, orange and grapefruit (total free radical absorption antioxidant potential, TRAP) was determined. Also measured dietary fiber, ascorbic acid, trace elements, total polyphenols and essential phenol content. The amount of fibers contained in the peel was found to be much higher (P <0.05) than that of the peeled fruit, but there was no significant difference in the fiber content between the peels of different fruits or the peeled samples of different fruits. lemon
