The cultures were after that extracted with ethyl acetate to cover 3.0 g of residue after removal of the solvent under reduced pressure. The extract was separated and purified by silica gel column chromatography (CC) and afforded two pure substances as yellow oil (substance 1) and yellowish crystal ( substance 2). The structure of the substances were established by comprehensive UV, IR and NMR spectroscopic analyses and substance 1 along with evaluation with the reported data. Base on spectra analyses the compound 1 was determined as Di-(2-ethylhexyl)phthalate and compound 2 as 5 (4’-ethoxy-2’-hydroxy-5’-methyl-2’,3’-dihydrofuran-3’-il (hydroxy) methyl-4-isopropyl-3-methyl-2-pyran-2-on).
