Isolation and identification of two new metabolites from silver leaf fungus Stereum purpureum
摘要:
Two new sterpurene sesquiterpenes have been isolated from Stereum purpureum and identified as 4,12-dihydroxysterpurene (1) and 5,12-dihydroxysterpurene (3) mainly on the basis of mass spectra and extensive nuclear magnetic resonance spectrometry of compounds 1 and 3 and their diacetate derivatives 2 and 4.
