Paxillamide: a Novel Phytosphingosine Derivative from the Fruiting Bodies of Paxillus panuoides

The new phytosphingosine‐type ceramide 1 , named paxillamide (=2,3‐dihydroxy‐N‐(1S,2S,3R)‐2,3‐dihydroxy‐1‐(hydroxymethyl)heptadecyl]tetracosanamide), was isolated from the CHCl₃/MeOH extract of the fruiting bodies of the Basidiomycete Paxillus panuoides, and its structure was elucidated by spectroscopic and chemical methods.
