Abstract

The invention relates to application of cinnamic acid in the preparation of drugs for preventing and treating livestock and poultry virus infection. Cinnamic acid has an activity resisting to poultry virus diseases, and can effectively prevent and treat infections of a bird flu H9 subtype virus, a bird flu H5 subtype virus, an infectious bursal disease virus LX strain, a nephropathogenic infectious bronchitis virus and an avian infectious laryngotracheitis virus, so that the death rate of diseased chickens is reduced, the survival rate of the poultry is effectively increased and the parturition performance of the poultry is effectively improved.

Description

technical field [0001] The invention relates to a new application of cinnamic acid, in particular to the application of cinnamic acid in the preparation of medicines for preventing and treating viral infection of livestock and poultry. Background technique [0002] Phenolic acid compounds are widely distributed in medicinal plants, such as ebony in Rosaceae, honeysuckle in Lonicera family, angelica and chuanxiong in Umbelliferae, etc. Various phenolic acids have a wide range of pharmacological activities, such as scavenging free radicals, anti-inflammation, anti-virus, immune regulation, anti-coagulation and anti-tumor effects. At the same time, studies have shown that ferulic acid has a significant inhibitory effect on cold viruses, respiratory syncytial virus and HIV. Professor Eich discovered that chlorogenic acid is a promising lead compound against HIV when he was studying plant metabolites as antiretroviral agents. In the process of studying Geranium sativa, it was f...
