Bacterial strains Bacterial strains used for testing included Staphylococcus aureus , Bacillus subtilis , Proteus vulgaris , Vibrio cholera , Klebsiella pneumonia

The present study was carried out for preliminary phytochemical screening for ten principle bioactive compounds in Petroleum ether, chloroform, ethyl acetate and ethanol extracts of roots of Memecylon edule collected from potheri forest, Kattankulathur in Tamilnadu. Chloroform and ethyl acetate extracts of seeds of Memecylon edule were also investigated against ten bacteria using disc diffusion method. Preliminary phytochemical screening revealed the presence of Alkaloids, Triterpenes, Flavonoids and saponins. The maximum activity was observed in chloroform extract against Bacillus subtilis with zone of inhibition (15mm) and minimum activity was observed in ethyl acetate extract against Yersinia enterocolitica and Vibrio cholera at inhibition range was observed (10mm). The results suggest ethyl acetate and chloroform extracts of this plant with moderent antibacterial activity and secondary metabolites of this plant used for wound healing property and other forms of bacterial infections.
