Piperine is a piperidine alkaloid from the group of acid amide alkaloids. It is the amide of piperic acid and piperidine and forms a colorless to yellowish solid with a monoclinic crystal structure. It is the source of the pungent pepper flavor. In order to develop a reliable colorimetric test for piperine, I need the substance to be relatively pure. Out of interest, I have decided to isolate the piperine from the black pepper myself using various methods. The yield is not particularly high but sufficient for my experiments.
