A new secoiridoid glucoside, insularoside, was isolated from Fraxinus insularis.The structural elucidation of insularoside by spectroscopic and chemical studies is described.The biogenesis of this glucoside is also briefly discussed. Key words: Fraxinus insularis; Oleaceae; leaves; secoiridoid glucoside; insularoside.

A secoiridoid glucoside, insularoside-6'''-O-β-D-glucoside, was isolated along with 9 known compounds from the leaves of Fraxinus insularis and its structure was determined to be 2 on the basis of spectroscopic and chemical studies. Direct comparison of this glucoside with a known secoiridoid glucoside, oleayunnanoside, led to the conclusion that the two were identical, and that the proposed structure 2a for oleayunnanoside should be revised to 2.
