title: Structures of new ceramides from the fruit bodies of Grifola frondosa.
abstract: Four new phytosphingosine-type ceramides, (2S,3S,4R)-2-[(2'R)-2'-hydroxydocosanoylamino]-1,3,4-octadecane triol (1), (2S,3S,4R)-2-[(2'R)-2'-hydroxytricosanoylamino]-1,3,4-octadecan etriol (2), (2S,3S,4R)-2-[(2'R)-2'-hydroxypentacosanoylamino]-1,3,4-octadec anetriol (3) and (2S,3S,4R)-2-[(2'R)-2'-hydroxyhexacosanoylamino]-1,3,4-octadeca netriol (4), have been isolated from the fruit bodies of Grifola frondosa. The structures of the new compounds were elucidated on the basis of their spectral data.
