METHOD FOR EXTRACTING VALUABLE COMPONENT FROM ERIOBOTRYA JAPONICA SEED

摘要

PPROBLEM TO BE SOLVED: To provide a new extraction method for selectively extracting amygdalin from crushed seeds of Eriobotrya japonica in high yield without using an organic solvent by a simple means requiring no removal of the solvent. PSOLUTION: The extraction method is to extract amygdalin from the crushed seeds of Eriobotrya japonica using supercritical COSB2/SB. In addition, the extraction method is to extract at 70-90C extraction temperature and 7.4-30 MPa extraction pressure for 3 hours. PCOPYRIGHT: (C)2008,JPO&INPIT
