Citrus are one of the most widely cultivated fruit crops. Citrus fruits are rich source of essential vitamins, minerals, fibers and bioactive phytochemicals, such as alkaloids, carotenoids, nitrogenous compounds and polyphenolics. The by-products derived from citrus wastes are considered to be an economic and renewable source for valuable compounds which can be used in pharmaceutical, nutraceutical, food and cosmetic industries. The review presents a detailed description on the recent advances with emphasis on the citrus derived nutraceuticals as potential source for various biological properties and physiological roles, such as anti-carcinogenicity, anti-mutagenicity, anti-allergenicity, anti-ageingactivitiy, and natural as well as important constituent in synthetic antioxidants. A comprehensive description on the citrus derived food and drinks as well as nutritious feed for animals has also been included.

柑橘是种植最广泛的水果作物之一。柑橘类水果富含必需维生素，矿物质，纤维和生物活性植物化学物质，例如生物碱，类胡萝卜素，含氮化合物和多酚。柑橘类废物产生的副产物被认为是可用于制药，营养保健，食品和化妆品行业的有价值化合物的经济和可再生来源。该综述对最近的进展进行了详细描述，重点是柑橘衍生的保健品，作为各种生物学特性和生理作用的潜在来源，例如抗癌性，抗诱变性，抗变应原性，抗衰老活性以及天然的作为合成抗氧化剂的重要成分。
