title: Antimicrobial agents from higher plants.  The quaternary alkaloids of Ptelea trifoliata.
abstract: Quaternary alkaloid extracts of Ptelea trifoliata showed potentially interesting antimicrobial activity.  Chromatographic examination showed the presence of six components.  Of these, choline and O-4-methyl ptelefolinium were known compounds.  Rational structures are proposed for the new alkaloids, O-4-methylhydroxyluninium, neohydroxylunine and pteleatinium salts.  Pteleatinium salt is responsible for the antimicrobial activity of the extracts of the plant.
