Última Biological activity of phototoxic compounds in Bidens squarrosaH.B.K. (Asteraceae) Phyton Pérez-Amador,MC; Muñoz Ocotero,V; García Jiménez,F. 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 anti-inflammatory potential was determined by the mouse ear edema test.

(Asteraceae) Phyton Pérez-Amador,MC; Muñoz Ocotero,V; García Jiménez,F. Leaves of Eupatorium morifolium Mill. were analyzed for phototoxic compounds, and the toxicity of their hexane extract was evaluated against Bacillus subtilis. The phototoxic compounds were analyzed by TLC. In the plate, pale blue spots indicated the presence of these compounds. This was confirmed by the UV extract spectrum and the antibacterial activity against Bacillus subtilis. The biological activity of the leaf extracts (hexane, ethyl acetate or methanol) was also studied. The antiinflammatory activity was determined using the edema test on mouse ears, and the bactericide activity was assayed against Bacillus subtilis and Escherichia coli. A strong anti-inflammatory activity was shown by the leaf extracts. The ethyl acetate extract exhibited the...

Ano: 2008 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1851-56572008000100003 Vernonia patensKunth, an Asteraceae species with phototoxic and pharmacological activity Phyton Pérez-Amador,MC; Muñoz Ocotero,V; Pérez Benitez,S; García Jiménez,F. The presence of phototoxic compounds in stems and leaves of young plants of Vernonia patens Kunth was confirmed by TLC. These compounds were in smaller amounts in younger than in adult plants of this species. Only the stems presented specific activity of these compounds from the two study plant organs. It included characteristic UV bands at 200 and 300nm, and phototoxic activity against Bacillus subtilis (ATCC-6633). Stems and leaves of Vernonia patens also showed anti-inflammatory activity and bactericide potential.
