New ceramides from the flower of Albizia julibrissin

A new ceramide and its glycoside were isolated from the flower of Albizia julibrissin. Their structures were established as (2S,3S,4R,8E)-2-[(2′R)-hydroxyhexadecanoylamino]-8-tetra-cosene-1,3,4-triol (I) and 1-O-β-d-glucopyranosyl-(2S,3S,4R,8E)-2-[(2′R)-hydroxy-hexade-canoylamino]-8-tetracosene-1,3,4-triol (II) on the basis of chemical and spectroscopic studies.
