Two new secoiridoid glucosides, butyl isoligustrosidate and fraximalac
oside, were isolated from the leaves pf Fraxinus malacophylla, togethe
r with the known constituents, isoligustroside, fraxiformoside, isolig
ustrosidic acid, 1'''-0-beta-D-glucosylfraxiformoside, verbascoside, c
osmosiin, sitosterol-beta-D-glucoside and tyrosol. Their structures ha
ve been elucidated by chemical and spectroscopic methods.
