[Study on secondary metabolites of marine fungus Penicillium sp. FS60 from the South China Sea].

Objective: To study the secondary metabolites of the marine fungus Penicillium sp. FS60 from the South China Sea and their cytotoxicities.

Methods: The compounds were isolated from the culture of strain FS60 by various chromatographic methods (silica gel, reverse silica gel, Sephadex-LH20, preparative TLC, HPLC and PTLC) and recrystallization.

[Study on the chemical constituents of endophytic fungus Fimetariella rabenhorstii isolated from Aquilaria sinensis].

Objective: To study the chemical constituents of endophytic fungus Fimetariella rabenhorsti isolated from Aquilaria sinensis.

Methods: Chemical constituents of the fungus were isolated and purified by column chromatography and their structures were elucidated on the basis of spectral data.

Results: Five compounds were isolated and identified as 4-hydroxy-phenylethyl alcohol (1),nicotinic acid (2), D-galacitol(3), 2-anilino-1,4-naphthoquinone (4), N-phenylacetamide (5).

A novel sesquiterpene alcohol from Fimetariella rabenhorstii, an endophytic fungus of Aquilaria sinensis.

A novel sesquiterpene alcohol, named frabenol (1), was isolated from liquid cultures of Fimetariella rabenhorstii A20, an endophytic fungus of the agarwood-forming plant Aquilaria sinensis (Lour.) Gilg. The structure of the new compound was elucidated on the basis of spectroscopic methods.
