Studies on the constituents from the aerial part of Baccharis dracunculifolia DC

Abstract

Ten new glycosides, named dracunculifosides A-J, were isolated along with sixteen known glycosides from the aerial part of Baccharis dracunculifolia DC. (Compositae). The structures of these glycosides were determined on the basis of spectral and chemical evidence. These new glycosides consisted of β-D-glucopyranose or β-D-apiofuranosyl-(1 → 6)-β-D-glucopyranose, and most possess an (E)-caffeoyl group.
