Technology of ultrasound-enhanced supercritical extraction for magnolol and honokiol / 中草药

ABSTRACT

Objective: To explore the enhanced role of ultrasound on supercritical fluid extraction. Methods: With stability parameters of supercritical fluid extraction of Magnoliae Officinalis Cortex, taking magnolol and honokiol contents and extraction rate as the reference indicators, the extraction effect between ultrasonic and supercritical fluid and ultrasound-enhanced supercritical fluid was compared. Rusults Ultrasound-enhanced supercritical fluid extraction is superior to the others. Conclusion: Ultrasound could strengthen the supercritical fluid extraction of active ingredients from Magnoliae Officinalis Cortex.
