Abstract
The studies were carried out to evaluate the constituents in the aerial part ofIsodon excisus var.coreanus (Labiatae). From the aqueous fraction of methanol extract, compound 1 (α-[[3-(3, 4-dihydroxyphenyl)-1-oxo-2-propenyl]oxy]-3,4-dihydroxy-benzenepropanoic acid), compound II (9-methyl-dihydroferulic acid-4-O-β-D-glucopyranosyl (1→2)-α-L- rhamnopyranosyl (1→4)-β-D-glucopyranoside), compound III (ent-7α, 11α, 15β-trihydroxy-kaur-16-en-1-O-β-D-glucopyranoside) and compound IV (2α, 3β, 7α, 23-tetrahydroxy-olean-12-en-28-oic acid 28-O-β-D-glucopyranoside) were isolated and identified on the basis of their physicochemical and spectroscopic evidences[IR, FAB(−)MS,1H-NMR,13C-NMR, HMQC,1H-1H COSY and HMBC (Heteronuclear Multiple Bond Connectivity)]. Especially, New compounds II and III were named isodonin A and Isodonin B respectively.
