AB - Phototoxic compounds (polyacetylenes and thiophenes) and their biological activity were determined on Bidens squarrosa plants by measuring their antibacterial and anti-inflammatory potential. Phototoxic compounds were extracted with hexane, characterized by TLC, and their presence confirmed by U.V. spectrum of their extracts and bactericidal potential. Antibacterial activity of the hexane, ethyl acetate and methanol extracts was measured against Bacillus subtilis and Escherichia coli, and their antiinflammatory potential was determined by the mouse ear edema test.
