Aranorosinol A and aranorosinol B, two new metabolities from Pseudoarachniotus roseus: Production, isolation, structure elucidation and biological properties.

Abstract

Two new secondary metabolites, aranorosinol A (1) and aranorosinol B (2), were isolated from a strain of Pseudoarachniotus roseus. Their structures were elucidated on the basis of their spectral properties and chemical transformations and were found to be similar to aranorosin (3) isolated from the same strain.
