title: Cytotoxicity and antibacterial activity of ethanol extract from leaves of a herbal drug, boneset (Eupatorium perfoliatum).
abstract: The cytotoxic and antibacterial activity of an ethanol extract of leaves of a herbal drug, boneset (Eupatorium perfoliatum), was investigated. The extract showed potent cytotoxicity with EC(50) values (12-14 microg/mL) comparable to a standard cytotoxic agent, chlorambucil. The extract showed a weak antibacterial activity against gram-positive test organisms (Staphylococcus aureus and Bacillus megaterium).
