Diospyros melanoxylon

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] The olive-green fruit of the tree is edible[5]

Pharmacology
Tendu patta (leaf) collection

The leaf of the tree contains valuable flavones.[6] The pentacyclic triterpenes found in the leaves possess antimicrobial properties,[7] while the bark shows antihyperglycemic activity.[8] 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.[9]

Method of collection

Tendu leaves are used as a wrapper for Beedi. During the summer fresh leaves are produced by the suckers coming up from the soil. This is also enhanced by setting fire beneath Tendu tree. The fresh leaves are hand-picked by the tribals and dried in the sun for 10 days. This practice is seen in Maharashtra, Madhya Pradesh, Odisha and Chhattisgarh states of India. The State Government gives the licence for collection and processing of the tendu leaves through tender every year.[10]

Varieties

There is one named variety of this species, Diospyros melanoxylon var. tupru.[11]
