STUDY OF PHYTOCHEMICAL CONSTITUENTS AND ANTIMICROBIAL ACTIVITY OF LEAF EXTRACTS OF TRIBULUS SUBRAMANYAMII L. 

ABSTRACT

Tribulus species is among the medicinal plants that are used by south Indian traditional practitioners for the aphrodisiac, diuretic effect, reduce inflammation, purify the blood, stones in the bladder, cure skin and heart disease. However, the claims of therapeutic success of medicinal plants by traditional medicine practitioners are hardly subjected to scientific scrutiny.  Our study, based on evaluation of the in-vitro antimicrobial activity of ether, chloroform and ethanol extracts of Tribulus subramanyamii Linn against standards bacterial and fungal strains by using disc diffusion method. The MIC value of extracts against gram positive bacteria’s were ranging between 300 to 500 µg, gram negative bacteria were >600µg and all extracts were ineffective against fungi. The data obtained from the phytochemical analysis of the leaves of T.Subramanyamii indicated the presences of carbohydrates, steroids and glycosides.
