Abstract

The invention discloses a production method of high-purity piperine. The production method comprises the following steps: firstly extracting pepper essential oil from a pepper raw material through a supercritical CO2 fluid; then extracting pepper oil resin through the supercritical CO2 fluid, wherein a mixed solvent of ethanol and water is taken as an entrainer during the extraction process; and mixing the pepper oil resin obtained by supercritical extraction with edible oil for purifying the piperine, and purifying through edible alcohol and denatured alcohol to get the high-purity piperine. The method is as follows: firstly extracting the pepper essential oil; and then extracting a pepper oil resin component by adopting the mixed solvent of the ethanol and the water as the entrainer, then mixing the pepper oil resin with the edible oil for purifying the piperine, and finally purifying through the denatured alcohol and the edible alcohol to get the high-purity piperine. The method adopts a physical method for extraction, the extraction rate is high, impurities are few, a purification process is simple and easy to operate, and an obtained piperine product is high in purity, good in quality and high in added value, and has pure natural feature.

Description

technical field [0001] The invention relates to extraction and purification of pepper, in particular to a production method of high-purity piperine. Background technique [0002] Piperine is an active ingredient of black or white pepper of the piperaceae plant. It has unique curative effects such as analgesia, warming the middle and dispelling cold, appetizing and lowering qi, anti-inflammatory and detoxification. It is a necessary intermediate or additive for many drugs in the pharmaceutical industry. The application value cannot be underestimated. At present, the process of extracting piperine from pepper mostly adopts the process of solvent extraction and crystallization separation. This method extracts impurities such as essential oils, oleoresins, pigments, proteins, sugars, etc. in the raw materials. During the purification process, degreasing, Decolorization, impurity removal and other treatments, the process is complicated and a large amount of essential oils and re...
