title: [Antibacterial constituents against Helicobacter pylori of Brazilian medicinal plant, Pariparoba].
abstract: Four known compounds have been isolated from the aerial parts of the Brazilian medicinal plant Pariparoba (Pothomorphe umbellata). They were an alkaloid, a flavone, a dihydrocalcone, and a steroid. The chemical structures were established to be N-benzoylmescaline, wogonin, uvangoletin, and beta-sitosterol glucoside using spectral methods. Among these compounds, the main component N-benzoylmescaline showed significant antibacterial activity against Helicobacter pylori.
