title: Antinociceptive activity of the natural piperidine alkaloid hydrochlorides from Syphocampylus verticellatus.
abstract: In addition to 3'-methoxyluteolin and mixtures of sterols and triterpenes, the leaves of Syphocampylus Verticellatus yielded two piperidine alkaloid hydrochlorides, one of them has a novel structure. The alkaloids exhibit antinociceptive activity.
