15 Years Factory Supply Pure Black Pepper Extract 95% 98% Piperine powder 94-62-2 in bulk stock

Piperine is extracted from black pepper using dichloromethane.Aqueous hydrotropes can be used in the extraction to result in high yield and selectivity.The amount of piperine varies from 1-2% in long pepper, to 5-10% in commercial white and black peppers.Further, it may be prepared by treating the solvent-free residue from an alcoholic extract of black pepper, with a solution of potassium hydroxide to remove resin (said to contain chavicine, an isomer of piperine) and solution of the washed, insoluble residue in warm alcohol, from which the alkaloid crystallises on cooling.
