Tecomella undulata (Smith), a member of the family
Bignoniaceae, is one of the
co-dominant species in the desert of western Rajasthan and adjoining plains of Haryana. The plant is very
hardy and drought resistant, is used for afforestation and landscaping of dry tracts and is prized for
its high-quality timber and medicinal value. The plant parts are used for the cure of syphilis and
eczema and the bark possesses mild relaxant, cardiotonic and chloretic activities.
Chemical investigations of leaves of
T. undulata led to the isolation of triacontanol,
betulinic acid, oleanolic acid and ursolic acid. Triacontanol is an effective plant growth regulator while
both betulinic acid and ursolic acid are potent antihuman immunodeficiency virus (HIV). The leaves
of T. undulata could be a rich source of ursolic acid for further clinical studies.
Keywords: Tecomella undulata, triacontanol, betulinic acid, ursolic acid, antiHIV.
