Diospyros blancoi, (synonym Diospyros discolor), commonly known as velvet apple, velvet persimmon, kamagong, or mabolo tree,[1] is a tree of the genus Diospyros of ebony trees and persimmons. It produces edible fruit with a fine, velvety, reddish-brown fur-like covering. The fruit has a soft, creamy, pink flesh, with a taste and aroma comparable to peaches.[2]

It is widely distributed and native to the Philippines, but it is also native to eastern and southern Taiwan.[3][1][4] It has also been introduced to other parts of Southeast Asia, the Pacific Islands, South Asia, the Caribbean, Florida, and other tropical regions.[5]

Cultivation

It is a dioecious tropical tree that grows well in a diversity of soil, from sea level to Script error: No such module "convert". above sea level. Seed trees are normally planted Script error: No such module "convert". from each other; this one can be planted from Script error: No such module "convert". from each other. It needs a good distribution of rainfall through the year. Trees that were planted by seeds could take 6 or 7 years to give out fruit, but trees that were propagated by cuttings produce fruit in 3 or 4 years. It is a very productive tree.Script error: No such module "Unsubst".

The fact that fruits vary greatly – in shape, color, hairiness and taste – suggests that there is a great deal of genetic variation in the plant. Seedless cultivars exist, and are highly favored since in the normal varieties the large seeds occupy a considerable volume of the fruit.Script error: No such module "Unsubst".

Like that of other trees in Dyospiros, which includes ebony, Kamagong timber is extremely dense and hard and is famous for its dark color.Script error: No such module "Unsubst".

The wood is generally used for house construction which include flooring, post, doors, and windows, among others.[6] Finished products from kamagong wood, such as fine furniture and decoratives can be exported, provided that they are properly documented and approved by the Customs authorities.Script error: No such module "Unsubst". Kamagong is also popular for martial arts training implements such as bokken and eskrima sticks.[7]

Secondary metabolites

The leaves of velvet apple trees have been shown to contain isoarborinol methyl ether (also called cylindrin) and fatty esters of α- and β-amyrin.[8] Both isoarborinol methyl ether and the amyrin mixture demonstrated antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Staphylococcus aureus and Trichophyton mentagrophytes.[8] Anti-inflammatory and analgesic properties have also been shown for the isolated amyrin mixture.[8]

Governance

It is an endangered tree species and protected by Philippine law – it is illegal to export kamagong timber from the country without special permission from the Bureau of Forestry, Department of Environment and Natural Resources.Script error: No such module "Unsubst".
