RIO AMAZON Graviola is becoming increasingly well known as a source of antioxidants called annonaceous acetogenins.
Graviola (Annona muricata) is a small evergreen tree, 5 to 6m high, with large, dark green, glossy leaves that is native to the Amazon rainforest and other tropical areas of the Americas. It produces a large, heart shaped edible fruit that is 15 to 23 cm in diameter, is yellow-green in colour, and has white flesh inside. In Brazil, the juice is a popular drink, and is known as Guanábana.
