Abstract

|
Acer tegmentosum is a tree used to treat various liver diseases in Korea. There have been some concern regarding the safety of Acer tegmentosum due to some toxic chemical compounds in its stems. Supercritical fluid extraction (SFE) was employed to develop a removing method of toxic compounds from Acer tegmentosum. The toxic compounds were effectively extracted with ethanol modified supercritical fluid CO2.. The optimum condition of SFE was 100 bar of pressure, 40oC of extraction temperature, 3 mL/min of CO2 flow rate, 0.2 mL/min of modifier (ethanol) flow rate.
