Abstract

Two new piperidine alkaloids, piperoctadecalidine and pipereicosalidine have been isolated from the fruits of Piper retrofractum (Piperaceae) along with two known piperidine alkaloids piperine and pipernonaline. The structures of the new compounds were determined to be (2E,4E,14Z)-N-(2,4,14-octadecatrienoyl)piperidine and (2E,4E,16Z)-N-(2,4,16-eicosatrienoyl)piperidine, respectively, by spectral and synthetic methods. © 1992.
