【 摘 要 】

From the ethanolicextract of the stem of A. esperanzae ethyl and methyl fatty acid esters,fatty acids, aristolochic I and II acids, and β-cubebinwere isolated. In addiction asarinin, populifolic and 2-oxo-populifolic acids,aristolactams AIa and AII, and sitosterol 3-O-β-D-glucopyranosidewere also isolated and firstly described in the species. Asarinin and β-cubebinshowed antibacterial activity against Bacillus cereus and aristolochicacid I against Staphylococcus aureus and Listeria monocitogenes.
