Abstract

Abstract Previously, it was isolated from the fruiting bodies of the gilled mushroom Pholiota spumosa (Basidiomycetes, Strophariaceae), putrescine-1,4-dicinnamide, a phenylpropanoid derivative conjugated with polyamine putrescine never isolated before as a [...]

24. Structural Characterisation of Metabolites from Pholiota spumosa (Basidiomycetes)

Abstract

Three compounds of different biosynthetic origin were isolated from the fruiting bodies of the gilled mushroom Pholiota spumosa (Basidiomycetes, Strophariaceae). Fasciculol E, a lanostane triterpenoid conjugated to a depsipeptide unit, was isolated for the first time from genus Pholiota. In addition, the first isolation of putrescine-1,4-dicinnamamide as a natural compound is reported: its structure was established by single crystal X-ray diffraction, and by spectroscopic methods. Crystallographic analysis indicated the presence of a co-crystallised related dicinnamamide, namely the new compound (E)-2,3-dehydroputrescine-1,4-dicinnamamide, whose occurrence was confirmed by LC-MS analysis. An interesting evolutionary issue arises, following the observation that the cinnamamides produced by Pholiota spumosa bear an unsubstituted benzene ring, contrarily to those found in plants, which have always phenolic functionalities, and as such perform a variety of biological roles.

Abstract

Three labda-diterpenes have been isolated from the aereal parts of Nolana elegans. Their structures were elucidated by high resolution spectroscopic methods as labd-8alpha ,15-diol 1, 15-hydroxy-labd-8(17)-ene 2 and 3beta -acetoxy,15-hydroxy-labd-8(17)-ene 3. De las partes aéreas de Nolana elegans se aislaron tres diterpenos de esqueleto labdano. Sus estructuras fueron determinadas por espectroscopía de alta resolución como: labda-8alfa ,15-diol 1, 15-hidroxi-labd-8(17)-eno 2 y 3beta -acetoxi,15-hidroxi-labd-8(17)-eno 3.
