Rapid purification method for fumonisin B1 using centrifugal partition chromatography

Area of Science:

• Food Science
• Analytical Chemistry
• Mycotoxicology

Background:

• Fumonisin B1 (FB1) is a toxic mycotoxin produced by Fusarium fungi.
• FB1 is commonly found in maize products, raising food safety concerns.
• Efficient purification methods are needed for FB1 analysis and toxicological studies.

Purpose of the Study:

• To develop a novel purification method for producing large quantities of pure Fumonisin B1 (FB1).
• To utilize centrifugal partition chromatography for efficient FB1 isolation.

Main Methods:

• Extraction of FB1 from rice cultures using methanol/water.
• Purification using a strong anion-exchange column.
• Separation via centrifugal partition chromatography with a specific biphasic solvent system (methyl-tert-butyl-ether-acetonitrile-0.1% formic acid in water).
• Analysis using flow injection-mass spectrometry and HPLC-Corona-charged aerosol detection.

Main Results:

• The novel method successfully produced approximately 120 mg of FB1.
• The isolated FB1 achieved a purity level exceeding 98%.
• The process was effective starting from 200 g of rice culture.

Conclusions:

• The developed purification method is highly effective for obtaining substantial amounts of pure FB1.
• This method provides a reliable source of pure FB1 for analytical and toxicological applications.
• The use of centrifugal partition chromatography offers a promising approach for mycotoxin purification.
