K. Oleinikova,* N. N. Kirichuk, and Sh. Sh. Afiyatullov In continuation of research on biologically active compounds from extracts of marine isolates of fungi and micromycetes [1, 2], extracts of nine Far-Eastern strains of the marine fungus Penicillium antarcticum were investigated (Table 1). Strains of the fungus were cultivated for 14 d on malt-agar  and rice medium  that were prepared with seawater. Mycelia together with the medium were extracted with EtOAc. The culture extracts were concentrated at reduced pressure. The resulting dry solids were dissolved in EtOH (10%) and extracted sequentially with hexane, EtOAc, and BuOH. The hexane fractions were concentrated at reduced pressure and analyzed using GC-MS. Compounds were identified by comparing their mass spectra with those of standard compounds using the NIST98 database. Table 2 presents the results. Hexane fractions of all cultures contained linear paraffinic hydrocarbons, linear hydrocarbons with a terminal double bond, and their isomers. Strain 1
