Antimicrobial, hemagglutination and phytotoxic activity of crude ethanolic and aqueous extracts of Seriphidium kurramense.

Objective: To investigate the antimicrobial activity, hemagglutination and phytotoxic activity of crude ethanolic and aqueous extracts of Seriphidium kurramense.

Methods: The extracts were analyzed by agar well diffusion assays against five bacterial species: Staphylococcus aureus (S. aureus), methicillin-resistant S. aureus, Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, and Salmonella typhi. The extracts were also screened against six fungal species-Aspergillus niger, Aspergillus flavus, Alternaria solani, Rhizoctonia solani, Fusarium solani and Pleurotus florida-using the agar tube diffusion method. Additionally, hemagglutination and phytotoxic activities of the crude ethanolic and aqueous extracts were assessed.

Results: The crude ethanolic and aqueous extracts showed dose-dependent inhibition of the various tested fungal and bacterial strains. No hemagglutination activity was observed. Both the ethanolic and aqueous extracts showed dose-dependent phytotoxic activity toward Lemna minor.

Conclusion: The crude ethanolic and aqueous extracts of Seriphidium kurramense possess good antimicrobial and phytotoxic activities, but no hemagglutination activity.
