Development of biologically active compounds from edible plant sources-XIX: isolation of inhibitory compound on LDL-oxidation from the aerial parts of Sajabalssuk(Artemisia princeps Pampanini, Sajabalssuk)

Abstract

Sajabalssuk (Artemisia princeps PAMPANINI) was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and H₂O, successively. From the EtOAc fraction, two phenylpropanoids 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 phenylpropanoids were determined as eugenol (1) and (-)-sesamin (2). They were the first to be isolated from Sajabalssuk (Artemisia princeps PAMPANINI, Sajabalssuk).
