What is Annona?

Legal Definition
Annona is a genus of flowering plants in the pawpaw/sugar apple family, Annonaceae. It is the second largest genus in the family after Guatteria, containing approximately 166 species of mostly neotropical and afrotropical trees and shrubs. The generic name derives from anón, a Hispaniolan Taíno word for the fruit. Paleoethnobotanical studies have dated Annona exploitation and cultivation in the Yautepec River region of Mexico to approximately 1000 BC. It has several common names, including Guanabana, Graviola and Soursop.

Currently, seven Annona species and one hybrid are grown for domestic or commercial use, mostly for the edible and nutritious fruits; several others also produce edible fruits. Many of the species are used in traditional medicines for the treatment of a variety of diseases, though their efficacy as a medicine has yet to be validated scientifically. Several annonacaeous species have been found to contain acetogenins, a class of natural compounds with a wide variety of biological activities.
