Abstract: During our ongoing research on fungal strains from unexplored sources, the reinvestigation of the CHCl3-MeOH extract of the marine-facultative Aspergillus sp. MEXU 27854 yielded a new N-methyl cyclic pentapeptide (1) along with known butyrolactone II and PF1233 A. In addition, from the marine-facultative Gymnoascus hyalinosporus MEXU 29901, a new alternariol glucoside, 10-O-[ß-d-(4-methoxyl-glucopyranosyl)]-4-O-methylalternariol (2) and known alternariol 4-O-methyl ether, alternariol and beauvericin, were isolated. The structures of 1 and 2 were established by detailed spectroscopic data, and their absolute configuration was ascertained by Marfey’s analysis and HRESIMS-MS/MS data for 1, and by chemical degradation and optical rotation analysis for 2.
