Abstract

The invention relates to a preparation method of zeranol complete antigen. The preparation method is characterized by comprising the following steps: weighing 2mg by weight of ZER and dissolving into 3mL acetone, adding 10mg by weight of potassium carbonate and 1mu lof ethyl 4-bromobutyrate, and performing reflux for 24h at 60 DEG C. The antigen is high in valence and strong in sensitivity; and the preparation method is simple to operate, capable of being used for industrial production, and strong in practicability.

Description

technical field [0001] The invention relates to a preparation method of zearallol complete antigen. Background technique [0002] Zearalenol (Zeranol, ZER), also known as "right-ring tetradecone phenol", is the reduction product of the secondary metabolite Zearalenone (Zearalenone, ZEN) produced by Gibberella zebras during growth. Since ZEN is widely present in important crops such as corn, wheat, and sorghum, zearalanol may contaminate food and feed, and eventually lead to its residue in animal products. In addition, because ZER can improve the conversion rate of cattle and sheep feed and increase the lean meat percentage of cattle and sheep carcasses, it was once widely used as a growth promoter for cattle and sheep in the form of implantation. Although most of ZER will be metabolized in the body, some of it will remain at the implantation site. ZER and its metabolites have estrogen-like effects, can cause abortion, stillbirth, and even infertility in animals, and also h...
