M. Maridass and G. Raju

Abstract
 
 

The aim at the present study, preliminary phytochemical identification and antibacterial activity of six rhizomes of Adiantum capillus-veneris, A. lunulatum, A. raddianum  Presl., A. incisum Forssk., Christella parasitica (L.) Holttum, and Tectaria zeylanica (Houtt.) Sledge, were investigated by disc diffusion method.  The tested bacteria Aeromonas hydrophila, Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Psesudomonas aeruginosa, were tested and zone of inhibition formation of 24 hrs observed. The selected bacteria are very harmful to fish and human. The results of selected pteridophytes possess better antibacterial properties of all ferns species.
