Abstract

Two new benzoic acid derivatives, named methyl(S)-3-hydroxy-4-(2- hydroxy -6-methylheptan-2-yl)benzoate (1) and 2-hydroxy-3-(6- hydroxy-6-methylhept-1-en-2-yl)benzoic acid (2), were isolated from the ethanol extract of an endophytic fungus Aspergillus versicolor derived from the medicinal plant Euphorbia royleana. The structures of compounds (1-2) were elucidated using NMR and MS methods.

Keywords: Aspergillus versicolor; Benzoic acid derivatives; endophytic fungus.
