Abstract

A new butenolide-type fungal pigment, pulverolide (1) was isolated from the fresh fruiting bodies of Pulveroboletus ravenelii, together with a related known compound pulveraven A (2). The structure of pulverolide (1) was elucidated on the basis of spectroscopic studies including extensive 2D NMR experiments.
