| 1 | Phytochemical constituents and antibacterial efficacy of the flowers of Peltophomm pterocarpum(DC.) Baker ex Heyne显示文摘Objective:To investigate the preliminary phytochemistry and antibacterial activity of the flower extract of Peltophorum pterocarpum.Methods:Phytochemical analysis was done by using the standard methods given by Harbone.The methanolic flower extract were tested against Escherichia coli,Klebsiella pneumonia,Pseudomonas aeruginosa.Staphylococcus aureus. Bacillus cereus,Salmonella typhi,Serratia marsecens,Acinetobacter baumannii.Enterobacter sp., Proteus mirabilis.Enterococcus faecalis and Streptococcus pyogenes by the agar disc diffusion method.Results:Preliminary phytochemical screening of flower extract showed the presence of phenolic compounds,flavonoids.saponins,steroids,tannins,xanthoproteic,carboxylic acids, coumarins and carbohydrates.The flower extract of Peltophorum pteroearpum showed significant activity against four gram positive(Staphylococcus aureus.Bacillus cereus.Enlerococcus faecalis and Streptococcus pyogenes) and three gram negative bacteria(Proteus mirabilis,Acinetohacter baumannii and Serratia marsecens).out of 12 pathogenic bacteria studied.Conclusion:The findings of the present study confirm the presence of significant antibacterial activity against human pathogens in the flowers of Peltophorum pleracarpum. | Sukumaran S Kiruba S Mahesh M Nisha SR Miller Paul Z Ben CP Jeeva S | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，9： | 4 |
