Piper nigrum Oleoresin Source & Identity
The botanical entity is Piper nigrum L., a climbing vine of the pepper family, Piperaceae, grown across the humid tropics. The part used is the fruit, harvested unripe and dried until black. Leaves, stems and roots are not part of this black pepper oleoresin extract.
Oleoresin is a specific term. It describes a solvent extract that carries the volatile oil together with the pungent resin of a spice, and it differs from a pure essential oil, which holds only the volatile fraction, and from the ground spice itself. Here the oleoresin is made with ethanol.
Piperine, the pungent amide, a terpene-rich volatile oil and the resin are the constituent families of the fruit.
