Citrus fruits have a beneficial effect on human health because of their nutritional and antioxidant properties, and their consumption is associated with a decrease in the incidence of cardiovascular disease and reduced risk of certain cancers. Seven cultivars of mandarin and orange species from the Mediterranean area, grafted onto different rootstocks (Cleopatra mandarin and Troyer citrange), have been analysed. The influence of the rootstock on the content of bioactive compounds is discussed.
In all citrus cultivars and rootstocks studied, hesperidin and narirutin flavonoids were the main flavanone glycosides identified, β-cryptoxanthin and violaxanthin the most abundant carotenoids, limonene was the most abundant essential oil, calcium and potassium were the dominant macronutrients and, among the micronutrients, iron and boron represented the highest proportions.
We have been found clear differences in the content of bioactive compounds for the different groups, in agreement with the Citrus classification. Although both mandarin and orange varieties showed similar tendencies concerning the majority of bioactive constituents, the proportion of the individual nutrients ranged among different cultivars and our results indicated differences between rootstocks although it would be necessary to carry out more analyses, and with the new rootstocks obtained from different breeding programmes, to elucidate conclusive values.
柑橘类水果因其营养价值和抗氧化特性对人体健康有益，其消费与心血管疾病发病率降低和某些癌症风险降低有关。对来自地中海地区的七种甜橙和宽皮橘品种（克莱门氏小柑橘和特罗耶橙汁）进行了分析，研究了砧木对生物活性化合物含量的影响。
在所研究的所有柑橘品种和砧木中，均鉴定出了主要的类黄酮糖苷橙皮苷和柚皮苷，含量最丰富的类胡萝卜素为β-隐黄质和玉米黄质，最丰富的精油为柠檬烯，钙和钾是主要的大量营养素，而在微量元素中，铁和硼的比例最高。
我们发现不同组的生物活性化合物含量存在明显差异，这与柑橘的分类一致。尽管甜橙和甜橙品种在大多数生物活性成分方面表现出相似的趋势，但个别营养物质的比例在不同品种之间存在差异，我们的结果表明砧木之间存在差异，尽管有必要进行更多的分析，并使用不同的繁殖计划获得的新砧木来阐明结论性数值。
