Abstract
Two new metabolites were isolated from the biotransformation reaction of parthenin by Beauveria bassiana ATCC 7159 along with the known naturally occurring sesquiterpene lactones hymenolin and dihydrocoronopilin. The new metabolites: are 3beta,4beta,6beta-trihydroxy-10alphaH,11alpha-methyl-ambrosa-1 -en-12-oic acid-gamma-lactone and 3alpha,6beta-dihydroxy-4beta-hydroperoxy-10alphaH, 11alpha-methyl-ambrosa-1-en-12-oic acid-gamma-lactone. The structure elucidation of these compounds was achieved by different spectroscopic methods.Entities:
