Abstract

Sajabalssuk (Artemisia herba) was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and $H_2O$, successively. From the EtOAc and n-BuOH fractions, four sterols were isolated through the repeated silica gel and ODS column chromatographies. From the results of physico-chemical data including NMR, MS and IR, the chemical structures of the sterols were determined as ${\beta}-sitosterol$ (1), ergosterol peroxide (2), stigmasterol (3) and daucosterol (4). They were the first to be isolated from Sajabalssuk (Artemisia herba).

사자발쑥의 전초를 80% MeOH 용액으로 추출하고, 얻어진 추출물을 EtOAc, n-BuOH 및 물로 용매 분획 하였다. 이 중 EtOAc 분획과 n-BuOH 분획으로부터 silica gel과 octadecyl silica gel(ODS) column chromatography로 정제하여 4종의 sterol 화합물을 분리하였다. 각 화합물의 화학구조는 NMR, MS 및 IR 등의 스펙트림 데이터를 해석하여, ${\beta}-sitosterol$ (1), dehydroergosterol $5{\alpha},8{\alpha}-epidioxide$ (2), stigmasterol (3), daucosterol (4)으로 동정하였다. 이 화합물들은 사자발쑥에서 처음 분리되었다.
