Two new azaphilone alkaloids, peniphilones A and B (1 and 2), and a known congener, (+)-sclerotiorin (3), were isolated from the endophytic fungus Penicillium maximae by screening based on chemical analysis by UPLC-HRMS with our in-house extract library of natural sources. The structures of 1 and 2 were elucidated on the basis of NMR and HRESI-MS spectroscopic data.
