(6ar-cis)-hexahydro-4-methoxy - Uses and synthesis methods
product description
aflatoxin is a metabolite of strains producing Aspergillus flavus and aspergillus parasiticus (A.parasilicus), mainly aflatoxin B1, B2, G1, G2 and their metabolites M1, M2, P1, B2a, G2a, etc. They are a class of compounds with similar structures, of which M1 and M2 are derivatives of aflatoxin B1 and B2, aflatoxins B1 and B2 are metabolized in vivo to M1 and M2. Aspergillus flavus mainly produced aflatoxins B1 and B2, and Aspergillus parasiticus mainly produced aflatoxins G1, G2, B1 and B2. The main contaminant of food in China is Aspergillus flavus.
aflatoxin mainly pollutes grain, oil and its products such as peanuts, peanut oil, corn, rice, cotton seeds, etc. In addition, walnuts, almonds, hazelnuts, sorghum, wheat, soybeans and beans, potatoes, eggs, milk and dairy products, liver, sausages or dried fish and peppers can be contaminated by aflatoxin. From the data of my country's large-scale census of food pollution, some grains and oils and their products in high temperature and high humidity areas in southern my country are vulnerable to pollution, while North China, Northeast, and Northwest China are generally not contaminated by aflatoxin except for individual samples.
