Abstract A method was developed for the detection and quantitation of piperine in Piper nigrum. A reverse-phase liquid chromatographic system equipped with a C18 column with detection at 340 nm was used. A rapid 1 h acetone extraction followed by solvent dilution was used to avoid sample cleanup. The detection limit is 3 ng injected piperine, with 97.5-100.5% recovery of added piperine.
