Abstract

Abstract:

In this study, an orthogonal array design was used to optimize the supercritical CO2 extraction of volatile oil from amomum tsaoko fruits. The optimal extraction conditions were found to be extraction at 55 ℃ and 25 MPa for 60 min with a CO2 fl ow rate of 25 L/h. The oil yield under the optimized conditions was 2.86%. Moreover, the composition and structure of chemical compound found in the volatile oil obtained were analyzed by GC-MS.

Key words: Amomum tsaoko fruits, volatile oil, orthogonal array design, supercritical CO2, GC-MS
