Abstract
Pteridophytes are the first vascular land plants. Which have also been proved for the presence of antimicrobial substances against a number of pathogenic bacteria and is mainly due to the presence of various secondary phytochemicals viz. alkaloids, terpenoids, flavonoids, tannin, saponin and others. In the present study to investigate antibacterial properties of the selected pteridophytes obtained from Kerala and Tamilnadu against human pathogens. Leaf extracts of Elaphoglossum nilgiricum; Crepidomanes plicatum; Adiantum raddianum; Pityrogramma austroamericana; Pseudocyclosorus ochthodes; Dryopteris cochleata; Athyrium solenopteris; Microlepia speluncae; Lindsaea odorata and Pyrrosia heterophylla were collected, air dried and extracted with 80% of methanol. Antibacterial potential of leaf extracts were tested by the agar-well diffusion method against Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhimurium. The results of the present study was observed that methanolic extracts of Adiantum raddianum and Elaphoglossum nilgiricum had the best antibacterial activity against Salmonella typhimurium. The conclusion of the present study observed that phytochemical analysis of the all the plant extracts have confirmed the presence of glycosides and carbohydrates, terpenoids, steroids, saponins, tannins, and flavonoids. These active compounds of the all the plant extract have responsible for the may be acted as antibacterial activity of the present study.
Keywords: Ferns, pteridophytes, phytochemicals, antibacterial activity, leaves, agar media
