Abstract
Four new phytosphingosine-type ceramides, (2S, 3S, 4R)-2-[(2'R)-2'-hydroxydocosanoylamino]-1, 3, 4-octadecanetriol (1), (2S, 3S, 4R)-2-[(2'R)-2'-hydroxytricosanoylamino]-1, 3, 4-octadecanetriol (2), (2S, 3S, 4R)-2-[(2'R)-2'-hydroxypentacosanoylamino]-1, 3, 4-octadecanetriol (3) and (2S, 3S, 4R)-2-[(2'R)-2'-hydroxyhexacosanoylamino]-1, 3, 4-octadecanetriol (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.
