title: Constituents of the herb ofIsodon excisus var.coreanus.
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 (alpha-[[3-(3, 4-dihydroxyphenyl)-1-oxo-2-propenyl]oxy]-3,4-dihydroxy-benzenepropanoic acid), compound II (9-methyl-dihydroferulic acid-4-O-beta-D-glucopyranosyl (1-->2)-alpha-L- rhamnopyranosyl (1-->4)-beta-D-glucopyranoside), compound III (ent-7alpha, 11alpha, 15beta-trihydroxy-kaur-16-en-1-O-beta-D-glucopyranoside) and compound IV (2alpha, 3beta, 7alpha, 23-tetrahydroxy-olean-12-en-28-oic acid 28-O-beta-D-glucopyranoside) were isolated and identified on the basis of their physicochemical and spectroscopic evidences[IR, FAB(-)MS,(1)H-NMR,(13)C-NMR, HMQC,(1)H-(1)H COSY and HMBC (Heteronuclear Multiple Bond Connectivity)]. Especially, New compounds II and III were named isodonin A and Isodonin B respectively.
