Borojoa patinoi, commonly known as borojó, is a mid-sized (3 to 5m), tropical forest tree that belongs to the Rubiaceae family. It grows in the northwest area of Colombia in the Chocó Department and in the Esmeraldas Province of Ecuador, in areas of high humidity (over 85%) and an average temperature of 28°C, both in the wild and on local farms.

Borojó is an Emberá word meaning: boro = head, ne-jo = fruit - head-shaped fruit, or round, globulous fruit.

Fruit features

The fruit is large (about 12 cm length), with a round shape and brown color and average weight of 740-1000 grams. The pulp represents 88% of the total weight. Each fruit has 90 to 640 seeds. Borojo has high levels of protein, phosphorus, ascorbic acid, calcium and iron. [1]

Borojo is used in the preparation of jam, wine, desserts and traditional medicines with supposed aphrodisiac effects. It is also used by the local communities against hypertension, bronchial diseases and malnutrition.

A study commissioned at Rutgers University by Nutropical, a private company, found that borojo fruit powder had a high and significant content of polyphenols as measured by the Folin-Ciocalteu polyphenol test. Most notably, the researchers believe the key polyphenol found in borojo may be novel. Work continues to identify the compound and/or elucidate its chemical structure. An analysis conducted by the same company found borojo has an ORAC value of over 54 μmolTE/g (5400 µmolTE/100g). The form of the fruit tested, however, is not mentioned (fresh, freeze-dried, spray-dried, etc.).^[1]

Classification

Borojoa sorbilis is a very similar species, also used with commercial purposes. Borojó de la Amazonia (Amazonas borojo), Duroia maguirei, is a wild species in a different Rubiaceae genus, which grows up to 8m and has a smaller, edible fruit. Claes Persson (1999)

The DNA studies of samples from several Rubiaceae genera, have shown Borojoa is closely related to Alibertia, in particular Alibertia edulis. Fifteen other species such as Alibertia sessulis, Alibertia beertierifolia and the Stacyarrhena and Glossotipula genus also have similarities.
