title: Three new compounds from the marine fungus Penicillium sp.
abstract: Continuous research on the ethyl acetate extract of the fermentation broth of the marine fungus Y26-02 (Penicillium sp.) led to the purification of one known and three new compounds. Their structures were elucidated, respectively, as butyl 2-(4-oxo-5,6-dihydro-2H-pyran-3-yl) acetate (1), 4-hydroxyphenethyl 2-(4-oxo-5,6-dihydro-2H-pyran-3-yl) acetate (2), 3-hydroxybenzyl 2-(4-oxo-5,6-dihydro-2H-pyran-3-yl) acetate (3), and desoxypatulinic acid (4) on the basis of their spectroscopic and physico-chemical properties.
