Colorimetric determination of patulin produced by Penicillium patulum. 1982

T Subramanian

A quantitative method has been developed for the determination of patulin, a mycotoxin produced by Penicillium patulum. The fungus was grown separately in well defined liquid minimal medium, and on rice and bread for 15 days. Patulin was extracted with ethyl ether and determined colorimetrically, using phenylhydrazine hydrochloride. Recovery of pure patulin added to bread and rice was also studied. The lower limit of detection was 1 microgram/g.

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
