ABSTRACT
Objective:
To study the secondary metabolites of the endophytic fungus Aspergillus oryzae from Paris polyphylla var. yunnanensis in order to find new compounds.Methods:
The endophytic fungus A. oryzae was fermented by liquid fermentation. After extraction, silica gel and macroporous adsorption resin were used to separate and purify the extract. The structures of the compounds were identified according to their physical and chemical properties and spectroscopic data.Results:
Three compounds were isolated and their structures were identified as 3-amino-4,5-dihydroxy-4,6-dimethyl-2-(2-methylbutanoyl)cyclohex-2-enone (1), 12-N-methyl- cyclo-(L-tryptophyl-L-phenylalanyl) (2) and ditryptophenaline (3).Conclusion:
