Eight alkaloids, piperine, pellitorine, isopiperolein B, Pyroperine, dehydropipernonaline, 1-Cinnamoyl piperidine, dihydopiperine, retrofractamide A, along with 3,4 methylenedioxy cinnamaldehyde, were isolated from the fruits of Piper nigrum L.. Their structures were elucidated by spectroscopic methods. In vitro activity assay showed that pellitorine, isopiperolein B, retrofractamide A and dehydropipernonaline presented remarkable activity on lipopolysaccharide (LPS)-induce NO release.
