Bemerkungen / Hinweise / Abstract
Five mushrooms, Panellus serotinus, Lyophyllum connatum, Amanita pantherina, Sarcodon aspratus and Lepista nuda, have been investigated chemically. Two new ceramides, (2S,3R,4E,8E)-N-hexadecanoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol (1) and (2S,3R,4E,8E,9'Z,12'Z)-N-9',12'-octadecadienoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol (2), have been isolated from Panellus serotinus. Compound 2 was also isolated from Lyophyllum connatum. Two new ceramides, (2S,2'R,3R,4E,8E)-N-2'-hydroxypentadecanoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol (4) and (2S,2'R,3R,4E,8E)-N-2'-hydroxytetradecanoyl-2-amino-9-methyl-4,8-octadeca-diene-1,3-diol (5), have been isolated from Amanita pantherina with (2S,2'R,3R,4E,8E)-N-2'-hydroxyhexadecanoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol (3), a known synthetic compound. Compounds 3 and 4 were also isolated from Sarcodon aspratus and compound 3 was isolated from Lepista nuda. The structures of the new compounds were elucidated on the basis of their spectral data.
