Abstract
Adiantum lunulatum , a medic inal pteridophyte used as in treating various skin diseases including leprosy. In the present study, whole plant of Adiantum lunulatum evaluated for its antibacterial potential and phytochemical contents in various solvent extracts of the plant in increasi ng polarity towards bacterial species involved in skin diseases in human beings. Antibacterial activity was evaluated by disc diffusion method. The results indicated that the plant exhibited antibacterial activity in methanol extract. The methanol extract of the plant showed maximum level of activity towards Pseodomonas aeruginosa, a resistant strain towards amoxycilin and chloramphenicol. Petroleum ether and water extracts did not show any antibacterial activity towards any of the tested organisms. The pre sence of flavonoids and phenols observed in various extracts. Flavonoid and phenol content in methanol extract of the plant may be one of the reasons for their antibacterial activity. Methanolic extract of the plant exhibited minimum inhibitory concentrati on as 50 mg/ml and minimum bactericidal concentration as 25 mg/ml towards Pseudomonas aerogenosa.
