Abstract

By chromatography and GC/MS-analysis of the root extract from P. amalago, 36 amides of various aliphatic and aromatic acids were detected, among them about 30 hitherto unknown compounds. Pyrrolidides and isobutylamides prevail, but no piperidides have been detected. Main constituent was found to be 5′-methoxy-3′,4′-methylenedioxycinnamic acid pyrrolidide (15).
