Fumonisin B₂ from Fusarium moniliforme，10MG，F3771-10MG，Sigma

General description

Fumonisin B₂ (FB₂) is a diester of tricarballylic acid and polyhydric alcohols.. Fumonisins B₂ (FB₂) does not have one or more hydroxyl groups at the C5 or C10 positions.
Mycotoxin originally isolated from Fusarium sp, which grows on corn. Produces neural tube defects and craniofacial abnormalities in fetuses. Many strains of Aspergillus niger growing naturally on grapes are capable of producing fumonisin B₂, so it is now a concern for human consumption of grapes, raisins, and wine.

Application

Fumonisin B₂ (FB₂) from Fusarium moniliforme has been used:

• as a standard for the detection of FB₂ by high performance liquid chromatography (HPLC) in corn based food products
• used as standard in the determination of fumonisin B1 and B2 in corn and corn-based products by high-performance liquid chromatography
• as a standard in the determination of mycotoxins by HPLC
