AbstractSeven compounds (1-7) were identified from the cultivation of the endophytic fungus Exophiala oligosperma (EN-21) that was isolated from the inner tissue of the marine red alga Laurencia similis. Their structures were identified with spectroscopic and chemical methods as 2-phenoxynaphthalene (1), (2S, 3R, 4E, 8E)-1-O-beta-D-glucopyranosyl-3-hydroxy-2-[(R)-2'-hydroxyoctadecanoyl] amino-9-methyl-4, 8-octadeca-diene (2), (22E,24R)-ergosta-7,22-dien-3 beta,5 alpha,6 beta-triol (3), (22E, 24R)-3 beta, 5 alpha, 9 alpha-trihydroxy-ergosta-7, 22-dien-6-one (4), (22E, 24R)-5 alpha, 6 alpha-epoxy-ergosta-8, 22-dien-3 beta, 7 alpha-diol (5), (22E, 24R)-ergosta-4, 6, 8(14), 22-tetraen-3-one (6), and euphorbol (7). This paper reports for the first time the chemical constituents of fungus Exophiala oligosperma and the discovery of compound 1 as a natural product from the fungus.; Seven compounds (1-7) were identified from the cultivation of the endophytic fungus Exophiala oligosperma (EN-21) that was isolated from the inner tissue of the marine red alga Laurencia similis.
