Taxonomy and etymology

The generic name Diospyros comes from a

D. lotus), derived from the Greek διόσπυρος : dióspyros, from diós (Διός) and pyrós (πῡρός). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit".[3][4]

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.[5]

The oldest fossils of the genus date to the Eocene, which indicate by that time Diospyros was widely distributed over the Northern Hemisphere.[6]

Chemotaxonomy

The leaves of

esters of α- and β-amyrin.[7] Both isoarborinol methyl ether and the amyrin mixture demonstrated antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Staphylococcus aureus, and Trichophyton interdigitale.[7] Anti-inflammatory and analgesic properties have also been shown for the isolated amyrin mixture.[7]
