2,2'-dimethoxy-4a,4a'-dehydrorugulosin (rugulin), a minor metabolite from Penicillium rugulosum.
A new metabolite was isolated from the culture of Penicillium rugulosum and its structure was determined from physico-chemical data. Accompanying metabolites skyrin and rugulosin were characterized by UV, IR, CD, mass and NMR spectra.
