Novel glycoinositolphosphosphingolipids, basidiolipids, from Agaricus

From the edible mushroom, the basidiomycetes Agaricus bisporus and Agaricus campestris, a novel carbohydrate homologous series of four glyco-inositol- phospho-sphingolipids, designated basidiolipids, was isolated and the const ituents purified. The chemical structures of the basidiolipids were elucida ted to be: Manp beta 1-2inositol1-phospho-ceramide, Galp alpha-6[Fucp alpha -2]Galp beta-6Manp beta-2inositol 1-phospho-ceramide, Galp alpha-6Galp alph a-6[Fucp alpha-2]Galp beta-6Manp beta-2 inositol1-phospho-ceramide and Galp alpha-6Galp alpha-6Galp alpha-6 [Fucp alpha-2]Gal beta-6Manp beta-2inosito l1-phospho-ceramide. All four glycolipids contained a ceramide which was co mposed of phytosphingosine and predominantly alpha-hydroxy-behenic and alph a-hydroxy-lignoceric acid.
