Abstract
A new 4-hydroxy-α-pyrone, namely capsulactone (1), was isolated from an endophytic fungus Penicillium capsulatum XL027 obtained from the leaves of Panax notoginseng. The structure and absolute configuration of 1 were elucidated through a combination of spectroscopic data and computed methods, as well as by comparison with literature data. Compound 1 exhibited weak activity against methicinllin-resistant Staphylococcus aureus with an MIC value of 100 μg/ml.
