Phenethyl alcohol glycosides and isopentenol glycoside from fruit of Bupleurum falcatum.

Investigation on the constituents of the fruit of Bupleurum falcatum L. resulted in the isolation of the three new glycosides, phenethyl alcohol 8-O-beta-D-glucopyranosyl-(1-->2)-O-beta-D-apiofuranosyl-(1-->6)-b eta-D- glucopyranoside, phenethyl alcohol 8-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside and isopentenol 1-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranoside along with five known glycosides, icariside D1, icariside F2, saikosaponin a, saikosaponin c and saikosaponin d. The structures of these compounds were elucidated on the basis of interpretation of chemical and spectral data.
