Abstract: Piper amides,with structural diversity and potential biological activities,are one of the main chemical components of Piper spp.. Since the first reported amide in 1939,piper amides have been one of the hot spots in natural products and medicinal chemistry.To date,more than 200 piper amides have been published,including isobutyl,pyrrolidine,piperidine types, etc. These amides showed insecticidal,antibacterial and antidepressive properties.Herein,the piper amides from P.flaviflorum were taken as an example to conclude the rule for structural determination of amide alkaloids by NMR data.

Key words: piper amides, Piper flaviflorum, Piperaceae NMR spectroscopic characteristics
