Abstract

Ixeris dentata formaalbiflora was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc,n-BuOH and H2O. Eight sesquiterpenes were isolated through repeated silica gel and octadecyl silica gel (C18, ODS) column chromatography of the EtOAc andn-BuOH fractions. Physicochemical analysis using NMR, MS and IR revealed the chemical structures of the sesquiterpenes, which were zaluzanin (1), 9a-hydroxyguaian-4(15), 10(14), 11(13)-triene-6, 12-olide (2), 3β-O-β-D-glucopyranosyl-8β-hydroxyguaian-4(15), 10(14)-diene-6,12-olide (3), 3-O-β-D-glucopyranosyl-8β-hydroxyguauan-10(14)-ene-6,12-olide (4), ixerinM (5), glucozaluzanin C (6), crepiside I (7), and ixerin D (8). This is the first time that these sesquiterpene lactones have been isolated from this plant. Compounds1, 2 and7 revealed relatively high cytotoxicities on human colon carcinoma cell and lung adenocarcinoma cell, while compounds5 and7 showed acyl-CoA: cholesterol acyltransferase (ACAT) inhibitory activity.
