Abstract

See full text

The present application relates to a technical field of separating kavalactone and flavokawain, and in particular, to a method for separating flavokawain and kavalactone, kavalactone, and microencapsulated kavalactone. The separation method includes: S1. grinding root of piper methysticum, extracting by supercritical carbon dioxide and collecting a residue for later use, in which an extraction temperature is 45-50° C. and an extraction pressure is 4-8 MPa; S2. extracting the residue by supercritical carbon dioxide, and collecting extracted oil for later use, in which an extraction temperature is 60-80° C. and an extraction pressure is 20-50 MPa; S3. performing re-extraction and adsorption on the extracted oil to obtain a primary product of the kavalactone; and S4. crystallizing the primary product of kavalactone to obtain the kavalactone. The obtained kavalactone is used for microencapsulated kavalactone.
