Studies On Antimicrobial Efficiency Of Citrullus Colocynthis (L.) Schrad: A Medicinal Plant, John Peter Paul J.

Ethnobotanical Leaflets

In the present study antimicrobial efficiency of Citrullus colocynthis (L.) Schrad was studied on seven bacteria Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi and Staphylococcus aureus. Ethanol, chloroform and petroleum ether extracts were used for antibacterial assay. Growth inhibitions were evaluated by the disc diffusion method. Ethanol extract is more active against Escherichia coli, Proteus vulgaris and Staphylococcus aureus. Pseudomonas aeruginosa and Bacillus subtilis show moderate activity in chloroform extract. Petroleum ether extract is more active against Escherichia coli. All extracts exhibited considerably less activity against Klebsiella pneumoniae and Salmonella typhi.

Phytochemical Screening And Antibacterial Activity Of Leaf Extracts Of Pterocarpus Marsupium Roxb. (Fabaceae), S. Ramya Et Al.

Ethnobotanical Leaflets

The present study was carried out to screen and evaluate the antimicrobial activity of bark and leaf extracts from Pterocarpus marsupium Roxb. Hexane, ethyl acetate and methanol extracts were tested against four selected Gram positive and Gram negative bacteria. Result indicated that phytochemical extracts of P. marsupium exhibited significant anti-bacterial activity at all dosage tested (1mg/ disc and 5mg/ disc). However, the inhibitory activity was found to be dose dependent. Ethyl acetate and methanol extracts were found to be more active towards the organisms tested than hexane extract. This study depicts that ethyl acetate and methanol extracts of bark and …
