This International Standard specifies a method for the determination, by high-performance liquid chromatography, of the piperine content of peppers (Piper nigrum Linnaeus), whole or powdered, as well as their extracts (oleoresins). This method enables the separation and, if necessary, the determination of the other alkaloids of pepper (isochavicine, isopiperine and piperittin).
