Supercritical Fluid CO2 Extraction of Radix Peucedani Volatile Oil and Componens Analysis

Abstract:

In this manuscript,the optimum supercritical fluid CO2 extraction process parameters of Radix Peucedani volatile oil was acquired by Orthogonal experimental design and described as follows:pressure 35 MPa,and 50 ℃ for 90 min,the dosage of Absolute ethyl alcohol entrainer was 20%,the separate temperature 45 ℃,the pressure 7~8 MPa,the extraction rate was 37.58%,76.32% of them are à-Pinene,á-Myrcene,Carene,Caryophyllene and so on.Compared with that of traditional method,the method provided here was a simple,efficient,and the ointment extracte with pure fragrance for yield oil.
