Descrizione generale

Aflatoxin G2 is a fungal secondary toxic metabolite synthesized by Aspergillus parasiticus, Aspergillus flavus, and Aspergillus nomius, 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.

Applicazioni

Aflatoxin G2 has been used as a standard to estimate the levels of aflatoxins by immunoaffinity column cleanup in:
  • peanut confection
  • Ginseng and other roots
  • olive oil, peanut oil, and sesame oil

Azioni biochim/fisiol

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

Attenzione

Possibly carcinogenic.
