Abstract

Abstract: Supercritical fluid extraction (SFE) of essential oil from dry rhizome of Ligusticum chuanxiong Hort was de-veloped. GC/MS was used for the determination of the composition of essential oil. Forty-four compounds were identified. Theconventional extraction method was conducted in parallel for comparison. The extracts were qualitatively compared by GC/MS.The yields of SFE and steam distillation-extraction were 4.16%(v/w) and 0.8%(v/w), respectively. Application of SFE ofessential oil from dry rhizome of Ligusticum chuanxiong Hort was preferable.

Key words: Supercritical fluid extraction (SFE), Supercritical fluid extraction (SFE), Essential oil, Essential oil, GC/MS, GC/MS
