目的 探究超声对超临界提取的强化作用。方法 在超临界提取厚朴稳定的工艺参数下,以提取物中厚朴酚与和厚朴酚的量和提取率为指标,比较了超声强化超临界提取、超声提取、超临界提取的效果。结果 超声强化超临界的提取效果明显优于两者的单独提取。结论 超声可强化超临界对厚朴有效成分的提取。

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.
