Six new partheniol metabolites were isolated from the biotransformation reaction with Mucor circinelloides ATCC 15242. These metabolites are: humula-1(10), 4, 7-trien-6alpha-ol 2, maali-3-en-8alpha-ol 3, aromadendrane-4alpha, 8alpha, 10alpha-triol 4, maaliane-4alpha, 8alpha, 9alpha-triol 5, maaliane-5alpha, 8alpha, 9alpha-triol 6, 5(9), 6-tricyclohumulane-4alpha, 8alpha, 10alpha-triol 7. The structural assignments of these metabolites were made possible by different spectroscopic means.
