Abstract

Abstract: A new compound, (3a S, 6a R )-4, 5-dimethyl-3, 3a, 6, 6a-tetrahydro-2H-cyclopenta [ b ]furan-2-one (2 ), along with two known metabolites, myrotheciumone A (1 ) and 4-oxo-4 H -pyron-3-acetic acid (3 ) was isolated from the ethyl acetate extract of fermentation broth of Xylaria curta 92092022. The structures of these compounds were elucidated on the basis of spectroscopic methods (UV, IR, HRESITOFMS, 1D NMR, and 2D NMR). Compounds1 and2 showed moderate antibacterial and phytotoxic activities. Abstract :
