Diospyros is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Depending on their nature, individual species are commonly known as ebony or persimmon trees. Some are valued for their hard, heavy, dark timber, and some for their fruit. Some are useful as ornamentals and many are of local ecological importance.
The generic name Diospyros comes from a Latin name for the Caucasian persimmon (D. lotus), derived from the Greek Diós () and pŷrós (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as "God's pear" and "Jove's fire".
The genus is a large one and the number of species has been estimated variously, depending on the date of the source. The Royal Botanic Gardens, Kew, list has over 1000 entries, including synonyms and items of low confidence. Over 700 species are marked as being assigned with high confidence.
The leaves of Diospyros blancoi have been shown to contain isoarborinol methyl ether (also called cylindrin) and fatty esters of α- and β-amyrin. Both isoarborinol methyl ether and the amyrin mixture demonstrated antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Staphylococcus aureus, and Trichophyton interdigitale. Anti-inflammatory and analgesic properties have also been shown for the isolated amyrin mixture.
