Quantitation of patulin pathway metabolites using gas-liquid chromatography. 1977

J Ehman, and G M Gaucher

A gas-liquid chromatographic system which allows most of the metabolites of the patulin pathway to be separated and quantitated has been developed. The metabolites are mostly phenols, and after conversion to their trimethylsilyl derivatives they are efficiently separated on a 3.18 mm O.D. stainless-stell column of 10% QF-1 on Gas-Chrom Q using a temperature programme. The detection limits for the three phenolic acids, 6-methylsalicylic acid, m-hydroxybenzoic acid and gentisic acid are all markedly lower than those obtained in previous systems. The usefulness of the system has been assessed by quantitating the patulin pathway metabolites present in culture filtrates of Penicillium urticae NRRL 2159A.

UI MeSH Term Description Entries
D010365 Patulin 4-Hydroxy-4H-furo(3,2-c)pyran-2(6H)-one. A mycotoxin produced by several species of Aspergillus and Penicillium. It is found in unfermented apple and grape juice and field crops. It has antibiotic properties and has been shown to be carcinogenic and mutagenic and causes chromosome damage in biological systems.
D010407 Penicillium A mitosporic Trichocomaceae fungal genus that develops fruiting organs resembling a broom. When identified, teleomorphs include EUPENICILLIUM and TALAROMYCES. Several species (but especially PENICILLIUM CHRYSOGENUM) are sources of the antibiotic penicillin. Penicilliums
D011714 Pyrans Pyran
D002849 Chromatography, Gas Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
