Perylenequinones from an endophytic sp. of .

The differential solvent extraction and further purification of fractions of endophytic sp. isolated from led to the isolation of further two perylenequinone compounds as 3,6,6a,9,10-pentahydroxy-7,8-epoxy-4-oxo-4,5,6,6a,6b,7,8,9-octahydroperylene () and 3,6,6a,7,10-pentahydroxy-4,9-dioxo-4,5,6,6a,6b,7,8,9-octahydroperylene (). Structure of compounds - was determined on the basis of detailed spectroscopic analysis, as well as by comparison with literature reports.
