Secondary Metabolites from the Fungus Quambalaria cyanescens

摘要

A phytochemical study of the fungus Quambalaria cyanescens led to the isolation of one new natural compound ( 1 ), along with four known compounds ( 2–5 ). The structures of the isolated metabolites were elucidated based on spectroscopic and spectrometric techniques. The fatty acid composition of Q. cyanescens was determined by GC/MS and found to consist of stearic, myristic, lauric, linoleic, cis-vaccenic, oleic, and pentadecanoic acids. All the isolated compounds were evaluated for their antimicrobial, antimalarial, and antileishmanial activities.
