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.
