    TRIACONTANOL AND TRITERPENES FROM TECOMELLA UNDULATA

    M. Mohibb E. Azam1, Pushpa Singh1 and A. Ghanim1

    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.
