Description and Uses

A tree, 9 to 15 m (30 to 50 ft.) tall, having a rounded and conical head, ovate glabrous leaves, and smooth, gray-brown bark. The flowers are large, white, and fragrant. The fruits are large, lightlemon or orange with a thin rind and grayish-yellow or pink flesh. Historically and botanically, the origin of the grapefruit is uncertain and appears to have developed from the Shaddok variety native to the West Indies. The plant is cultivated in the United States (Florida, California, Texas), East Asia, West Indies, Brazil, and Nigeria. The Citrus decumana variety yields the largest fruits (up to 10 kg). The parts used are the fruit and peel. Grapefruit has a fresh, citrus-like odor and a taste reminiscent of sweet and bitter orange to some degree.
Grapefruit essential oil is the volatile oil obtained by cold expression of the fresh peels of the fruit. The oil is a yellow, sometimes reddish liquid (often showing a flocculent separation of waxy material) with a pleasant citrus-like odor and flavor.
Its main constituents include limonene (90%), 2 to 3% volatile fraction containing oxygen compounds and sesquiterpenes, 7 to 8 % waxy fraction, C8 and C10 aldehydes, geraniol, cadinene, small amounts of citral and dimethyl anthranilate, and acids. A terpeneless oil can be prepared by vacuum distillation, yielding a more soluble and more stable concentrated oil. However, a certain amount of terpenes must be left in the oil to retain the characteristic freshness of citrus flavor.
A lower grade of essential oil that does not have application in flavor work is also obtained by steam distillation of the crushed peels or even from seeds.
The derivatives are juice and extract. Naringin, a bitter, white, crystalline glucoside, is found in the blossoms and the flavedo of the fruits. Naringin yields rhamnose and naringenin (C15H12O5) on hydrolysis. A naringin extract, prepared from the expressed peels, is used in flavors.

grapefruit oil is used as a fragrance and also as an active component with anti-irritant properties. grapefruit oil is indicated for work with the lymphatic system.
