Identification and determination of organic acids in cultivation medium ofPenicillium vermiculatumdang

摘要

2E,7E-4,9-dioxo-2,7-decadienoic, 2E,7E-9-oxo-2,7-decadienoic and 2Z,4E-2-methyl-2,4-hexadienoic acids were isolated from the filtrate ofPenicillium vermiculatumDang. The presence of 2E,2′E,7S,7′E-4,9-dioxo-7-(4′,9′-dioxo-2′,7′-decadienoyloxy)-2-decenoic acid was confirmed by chromatography. HPLC was used for the determination of these acids in the cultiva
