The metabolites of an endophytic fungus
Pseudallescheria boydii
L32 derived from the mangrove plant
Myoporum bontioides
A.Gray were studied. The monomeric compounds were isolated from the fermentation product by the modern chromatography technology. The structures were determined by spectral analysis. The antibacterial activity was tested via the dilution method. Ten metabolites were purified including 2,2′-oxybis(
1

4
)-di-tert-butylbenzene (
1
),livistone B (
2
),simplicildone A (
