From the bioactive compounds in citrus peel and peel-related important horticultural traits,this article reviewed the recent study advances and proposed the future perspective. Various bioactive compounds are abundant in citrus peel,including pectin,essential oil,flavonoids,limonoids,carotenoids and coumarins,which confer the characteristic nutrient trait of citrus. Due to pleiotropic functions of these bioactive compounds in the health maintenance and disease prevention/treatment,citrus peel is the promising material ideally for the production and development of functional food,natural health products and drugs. The peel-related horticultural traits are critical to the commercial value of citrus fruits. As some key genes such as CCD4b and Ruby were recently unraveled in the regulation of peel colour,great knowledge has been achieved about the molecular mechanism of the development of the red and purplish-red citrus peel. Peel roughness,thickness,firmness and peelability are also important traits,which directly affect the external quality,tolerance to storage/transportation and convenience of raw eating,and closely related to some physiological disorders such as rough fruits and puffing. However,only modest progress has so far been made in the physiological and molecular mechanism underlying these traits. With the higher demand for the overall nutrient and quality of citrus fruit,more efforts should be invested in the genetic regulation for the metabolism of the bioactive compounds in citrus peel and peel-related horticultural traits.
