Abstract
The present invention relates to a process of making high purity piperine for nutritional and nutraceutical application. This process recovers piperine from piperine-containing oleoresin by using isourea, urea or a urea derivative to remove organic matter other than piperine from the oleoresin. Preferrably, the process recovers piperine from oleoresin of fruit of piper nigrum or piper longum. More preferably, the process recovers piperine from oleoresin of fruit of piper nigrum, i.e. black pepper.
