Coffea bengalensis Roxb. is a small shrub distributed in south and southeast Asia. The native distribution has been documented in Bangladesh, India (Arunachal Pradesh, Assam, Bengal, Meghalaya, Orissa, Rajasthan and Sikkim), East Himalaya, Bhutan, Myanmar, Nepal, Thailand and Vietnam.
This plant has low caffeine content, therefore it is rarely studied and used in the industry nowadays. The degradation of caffeine, which is negligible in the leaves of Arabic coffee, is also very slow in Coffea bengalensis.
About nine polyphenolic compounds was found in the leaf, pericarp and seed. Of the nine compounds, five are phenolic acids (caffeic acid, chlorogenic acid, ferulic acid, p-coumaric acid and sinapic acid) and other 4 compounds identified as flavonols (quercetin, isoquercitrin, rutin and kaempferol).
In Nepal, C. benghalensis flowers were used as a treatment for excessive bleeding during menstruation.
