The invention provides a technological method of extracting and separating capsaicin, capsicum red pigment and capsicum oleoresin crude products from red pepper, which adopts the red pepper pulverized with a certain particle size as material and hydrous ethanol as extraction solvent, and three-stage extraction method for the preparation of the three extracts of capsaicin, capsicum oleoresin and capsicum red pigment separated in the extraction phase. The three extracts are respectively vacuum concentrated and distilled, and the crude products of capsaicin, capsicum red pigment and capsicum oleoresin can be gotten after the solvent recovery and solvent residue removal. The extracting and separating method separates the capsaicin, capsicum oleoresin and capsicum red pigment in the extraction phase by using the same extraction tank and solvent, avoids the trouble of separating the capsaicin and capsicum red pigment in the late workshop section, eliminates the alkali and acidification treatments or the separation craft of column chromatography, facilitates the improvement of the output ratio of capsicum red pigment and capsaicin. The technological method of extracting and separating capsaicin, capsicum red pigment and capsicum oleoresin crude products from red pepper has the advantages of simple technique, easy operation and control, less equipment investment, easy solvent recovery and reuse, low cost, short cycle, high yield of active ingredient, and better suitability for commercial and mass production.
