Abstract: This research was carried out to study the secondary metabolites of endophytic fungus Aspergillosis fumigatus from Euphorbia royleana. The endophytic fungus A. fumigatus was fermented by solid fermentation,and purified by various chromatographic methods after extraction. The structures of the compounds were identified by1 H-NMR,13 C-NMR and HSQC,HMBC spectra and physicchemical properties. Three compounds were isolated and their structures were identified as 3-( 3,4-dihydroxybenzoyl)-5-( 3,4-dihydroxyphenyl)-6-methyl-5,6-dihydro-2 H-pyran-2-one( 1),hydroxysydonic acid( 2) and 11-hydroxysydonic acid( 3). Compound 1 is a new compound.
