Abstract:
The secondary metabolites of the endophytic fungus
Aspergillus fumigatus derived from
Euphorbia royleana was studied. Silica gel column chromatography, Sephadex LH-20 gel and liquid chromatography were used to separate and purify of
Aspergillus fumigatus. The compounds were identified according to their physical and chemical properties and spectroscopic data. Three compounds (
1 —
3 ) were isolated from the endophytic fungus
A. fumigatus. Their structures were identified as methyl 4-(3,4-dihydroxyphenyl)-2-hydroxy-4-oxobutanoate (
1 ), arctiin (
2 ) and 3-hydroxy-4-methoxy-phenylethanol (
3 ). Compound
1 is a new phenolic component named as methyl 4-(3,4-dihydroxyphenyl)-2-hydroxy-4-oxobutanoate (
1 ).
