Poivres, oléorésines de poivres — Détermination de la teneur en pipérine — Méthode par chromatographie en phase liquide à haute performance

This document specifies a method for the determination of piperine content of peppers (Piper nigrum Linnaeus), whole or ground, as well as their extracts (Oleoresins) by high performance liquid chromatography.

This method also enables the separation and, if necessary, the determination of the other alkaloids of pepper (isochavicine, isopiperine and piperittin).
