compounds (2, 4, 5, 7, 8, 11, 14–17) from the culture extract of the endophytic fungus Nodulisporium sp. from Juniperus cedre from Gomera Island. The structure of dictafolin-A, previously erroneously assigned as structure 6, is not identical with 2,3-dihydro-5-methoxy-2-methylchromen-4-one, isolated in this investigation. The structures of new compounds were determined by spectroscopic methods (mainly extensive
