Bioactive Spectrum of the Three Selected Medicinal Flowers on Chosen Microbes

The aqueous, ethanol and benzene extracts of flower from three medicinal plants of Tribulus terrestris, Pavetta indica and Saraca asoca were examined for possible sources of antimicrobial activities and phytochemical constituents. Occurrence of the phytochemicals in all the three different plant flowers mainly depends upon the solvent efficiency. Moreover presence of carbohydrates, alkaloids, tannins, saponins, Flavanoids, anthraquinone, glycosides, steroids, terpenoids and sterols Though, Flavanoids, Anthraquinone and glycosides absence in benzene flower extract of S. asoca. The preliminary evaluations of both the aqueous and solvent benzene ethanol extracts exhibited appreciable inhibitory activities on the tested pathogenic bacterial isolates at concentration of 30mg m/L. Results of inhibition zone in S. asoca showed more therapeutic activity where the benzene flower extract demonstrated significant (P<0.05%) inhibitory activity 49±4.1mm in diameter on the tested K. pneumonea bacterial isolates. Similarly ethanol extract of P. indica flower showed of highest range of inhibition zone between (30±5.3 to 40±7.1 mm) observed on S. aureus and S. typhi respectively. From, this study explained the above said thee medicinal plant flower extracts were definitely used for the potential antibacterial agent.
