Separation of piperine from pepper supercritical CO2 extract

According to the results of single factor investigation, it is preliminarily determined that the separation process of piperine in the supercritical CO2 extract of pepper is: dripping absolute ethanol in a constant temperature water bath at 40℃, the dosage is 1:5 (w/v), and then 1℃/ The cooling rate of 5min is reduced to 0℃, and it is placed at 0℃ for 4h to crystallize.
