果皮，果肉和种子提取物的三个品种，即Phlegraean柑橘（柑橘reticulata），金桔（柑橘），克莱门汀（柑橘clementina）进行了比较和表征的光合色素含量，总多酚量，抗氧化活性和维生素C，以评估每个品种的功能化合物的量。多酚类物质含量以糙皮柑橘最高，尤其是果皮和种子，而金桔则以果肉中的含量最高。结果表明，金桔和大柑果皮中的抗氧化活性最高，而果肉中的抗氧化活性最高。结果表明，糙皮柑种子的抗氧化活性最高。结果表明，银汉柑果实各部位维生素C含量均以种子最高。总叶绿素含量是可比的果皮中的不同品种，在果肉中的最高量被发现在克莱门蒂，而枇杷种子显示出最大的值。至于类胡萝卜素总量，柑橘果皮和果肉中的类胡萝卜素含量高于其他两个品种，而柑橘种子中的类胡萝卜素含量最高。在分析的品种Phlegraean柑橘可能被认为是最有前途的多酚和抗氧化剂的来源，相比，克莱门蒂和金桔，特别是在种子中发现的功能分子。此外，无论品种，这项研究还强调了水果的部分通常被认为是废物的重要属性。
Peel, pulp and seed extracts of three mandarin varieties, namely Phlegraean mandarin (Citrus reticulata), Kumquat (Citrus japonica), and Clementine (Citrus clementina) were compared and characterised in terms of photosynthetic pigment content, total polyphenols amount, antioxidant activity and vitamin C to assess the amount of functional compounds for each cultivar. The highest polyphenols content was found in the Phlegraean mandarin, especially in peel and seeds, whereas Kumquat exhibited the highest polyphenols amount in the pulp. The antioxidant activity was higher in the peel of Phlegraean mandarin and clementine compared to Kumquat, which showed the highest value in the pulp. The antioxidant activity peaked in the seeds of Phlegraean mandarin. The vitamin C in the Phlegraean mandarin was the highest in all parts of the fruit, especially in the seeds. Total chlorophyll content was comparable in the peel of different cultivars, in the pulp the highest amount was found in clementine, whereas kumquat seeds showed the greatest values. As regards total carotenoids, peel and pulp of clementine exhibited higher values than the other two cultivars, whereas the kumquat seeds were the richest in carotenoids. Among the analysed cultivars Phlegraean mandarin may be considered the most promising as a source of polyphenols and antioxidants, compared to the clementine and Kumquat, especially for the functional molecules found in the seeds. Moreover, regardless of cultivars this study also highlights important properties in the parts of the fruit generally considered wastes.
