Mitragyna tubulosa: Comprehensive Guide to the Western Ghats Tree
Native to the lush Western Ghats of India and the tropical environments of Sri Lanka, Mitragyna tubulosa is a prominent tree species belonging to the Rubiaceae family. This towering plant, capable of reaching heights of up to 15 meters, thrives in elevated regions up to 900 meters above sea level.
It plays a vital ecological role in its native habitat and has drawn scientific interest due to its specific chemical constituents and woody structure.

Morphology
Mitragyna tubulosa develops into a substantial tree with a robust canopy, characterized by a growth habit typical of tropical hardwoods within the coffee family. Its physical structure allows it to compete for light in dense, moist forested areas.
Applications
Scientific research into the leaf and bark tissues of Mitragyna tubulosa has identified a diverse array of alkaloids. These specialized organic compounds include:
- Mitraciliatine and rhynchociline
- Ciliaphylline and ciliaphylline-N-oxide
- Rotundifoline and isorotundifoline
- Rhynchophylline and isorhyncophylline
- Mitraphylline and isomitraphylline
The presence of these phytochemicals makes the species a compelling subject of pharmacological study, focusing on the potential bioactivity of its isolated alkaloids.
Interesting facts
The tree was first described scientifically under the basionym Nauclea tubulosa by the botanist George Arnott Walker-Arnott, based on specimens collected in Ceylon (modern-day Sri Lanka) by G.H.K. Thwaites during the mid-19th century.
