Description

General description

Ochratoxin A is one of the mycotoxins typically produced by the species of Aspergillus genus. It is a commonly found secondary metabolite in cereals, coffee, grape must, wine, beer, etc.

Application

Ochratoxin A may be used as an analytical reference standard for the determination of the analyte in:
• Traditional Chinese medicines by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).
• Wine samples by reversed-phase HPLC with fluorescence detection (HPLC-FLD).
