Four novel metabolites from microbial transformation of curcumol by Cunninghamella blakesleana.
Further study on the microbial transformation of curcumol (1) by Cunninghamella blakesleana (AS3.970) led to the isolation of four novel metabolites. Their structures were elucidated as 3beta-hydroxy curcumol (2), 12-hydroxy curcumol (3), 1alpha-hydroxy-10beta,14-epoxy curcumol (4) and (2S,4S,5S,7S)-10-hydroxymethyl-7-isopropyl-2-methoxy-4-methyl-1-oxaspiro[4,6]undec-10-en-8-one (5) on the basis of spectral methods. All of them were characterized as new compounds.
