General description

Aflatoxin G₂ is a fungal secondary toxic metabolite synthesized by Aspergillus parasiticus, Aspergillus flavus, and Aspergillus nomius,[1] species that are found in tropical and subtropical regions of the world. Aflatoxin Gs (AFGs) are derivatives of difuranocoumarin and contain a bifuran group linked to a coumarin nucleus and a lactone ring.[2]

Application

Aflatoxin G₂ has been used as a standard to estimate the levels of aflatoxins by immunoaffinity column cleanup in:

peanut confection[3]
Ginseng and other roots[4]
olive oil, peanut oil, and sesame oil[5]

Biochem/physiol Actions

Aflatoxins are hepatocarcinogenic and act as food contaminants in peanuts, fruits, cereals, corn, and dry fruits.[1]

Disclaimer

Possibly carcinogenic.

Aflatoxins in Food and Feed: An Overview on Prevalence, Detection and Control Strategies.

Dipendra K Mahato et al.

Frontiers in microbiology, 10, 2266-2266 (2019-10-23)

Aflatoxins produced by the Aspergillus species are highly toxic, carcinogenic, and cause severe contamination to food sources, leading to serious health consequences. Contaminations by aflatoxins have been reported in food and feed, such as groundnuts, millet, sesame seeds, maize, wheat

The use of regenerated immunoaffinity columns for aflatoxins B1, B2, G1 and G2 in peanut confection.

Maria Helena Iha et al.

Journal of chromatography. A, 1483, 1-7 (2017-01-09)

The aim of this study was to investigate the feasibility of using multitime-regenerated immunoaffinity column (IAC) for aflatoxins B1, B2, G1 and G2 in peanut confection. After each use, the IAC was washed immediately with phosphate-buffered saline and stored for >12h

Determination of aflatoxins and ochratoxin A in ginseng and other botanical roots by immunoaffinity column cleanup and liquid chromatography with fluorescence detection.

Mary Trucksess et al.

Journal of AOAC International, 89(3), 624-630 (2006-06-24)

Mycotoxins are toxic secondary metabolites produced by certain molds and are common contaminants of many important food crops, such as grains, nuts, and spices. Some mycotoxins are found in fruits, vegetables, and botanical roots. These contaminants have a broad range

Meritxell Ventura et al.

Journal of chromatography. A, 1048(1), 25-29 (2004-09-30)

An easy method for the determination of aflatoxins B1, G1, B2 and G2 in Rhammus purshiana by LC coupled to mass spectrometry has been developed. Aflatoxins were extracted with a mixture of methanol and water and then it was purified
