Two new triglycosides of oleanane-type triterpenes, rotundioside E (3) and F (1), isolated from the leaves of Bupleurum rotundifolium L. were identified as 16α, 28-dihydroxyoleana-11, 13 (18)-dien-3β-yl α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-fucopyranoside (3) and 13β, 28-epoxy-16α-hydroxyoleana-11-en-3β-yl α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-fucopyranoside (1), respectively, on the basis of chemical and spectroscopic evidence.
