AflatoxinG2 - Uses and synthesis methods
product description
Aflatoxin is a toxic metabolite of Aspergillus flavus and Aspergillus parasiticus. It is a kind of compound with basic structure containing difuran ring and coumarin (oxonaphtho ketones). Twelve kinds have been isolated and identified. Aflatoxin is easily soluble in chloroform and methanol but insoluble in n-hexane, petroleum ether and ether. Fluorescence is generated under long-wave ultraviolet light, which is named B1,B2,G1,G2,M1,M2,P1,R1,GM and toxic alcohol according to different fluorescence colors, RF values and structures. Among them, B1 has the highest yield, the greatest toxicity and the strongest carcinogenicity. Aflatoxin is heat-resistant and can only be cracked at 280 ℃, so there is little damage at general cooking temperature. It is very stable in neutral and weak acidic solution, slightly decomposed in acidic solution with pH1 ~ 3, and rapidly decomposed and destroyed in solution with pH9 ~ 10. In 1961, it was discovered that peanut cakes contaminated by Aspergillus flavus can induce liver cancer in rats. In 1962, aflatoxin was identified and proved to be a strong carcinogen. Aflatoxin with double bonds at the end of difuran ring in the structure is easy to form epoxidation metabolites and enhance its toxicity, carcinogenicity and mutagenicity. Aflatoxin mainly pollutes grain and oil and its products, such as peanuts, peanut oil, corn, rice and cottonseed. Aflatoxin B1 is used as the pollution index in domestic food testing, which can be detected by thin layer chromatography and high pressure liquid phase method.
