Diospyros melanoxylon, the Coromandel ebony or East Indian ebony, is a species of flowering tree in the family Ebenaceae native to India and Sri Lanka; it has a hard, dry bark. Its common name derives from Coromandel, the coast of southeastern India. Locally it is known as temburini or by its Hindi name tendu. In Odisha , Jharkhand, and Assam, it is known as kendu. The leaves can be wrapped around tobacco to create the Indian beedi,[3] which has outsold conventional cigarettes in India.[4]

Pharmacology

The leaf of the tree contains valuable flavones.[5] The pentacyclic triterpenes found in the leaves possess antimicrobial properties,[6] while the bark shows antihyperglycemic activity.[7] The bark of four Diospyros species found in India has been determined to have significant antiplasmodial effects against Plasmodium falciparum, which causes malaria in humans.[8]
