Abstract

The invention relates to the technical field of livestock medication and specifically relates to a compound formula of gallic acid and rhein, a preparation method and an application thereof. The compound formula is capable of preventing and treating viral and bacterial diseases of livestock. The compound formula of gallic acid and rhein comprises the following components in parts by weight: 75-80parts of gallic acid and 20-25 parts of rhein. An in vivo test proves that the compound formula of gallic acid and rhein has the function of preventing and controlling bird flu H9N2 subtype, bursal disease virus, chicken escherichia coli, and the like, and is capable of effectively killing pathogenic bacteria of animals, such as bovine escherichia coli, swine escherichia coli and swine bacillus cereus.

Description

Technical field [0001] The invention relates to the technical field of livestock and poultry medicine, in particular to a compound of gallic acid and rhein, a preparation method and application thereof, and the product can prevent and treat viral and bacterial diseases of livestock and poultry. Background technique [0002] Gallic acid (GA) is also known as gallic acid, its structure is shown in formula I, its chemical name is 3,4,5-trihydroxybenzoic acid, its CAS registration number is 149-91-7, its molecular formula is C7H6O5, and its molecular weight is: 170.12. [0003] [0004] The properties of the product are white or light brown needle-like crystals or powders (crystallized from anhydrous methanol and chloroform). When sublimated at 210°C, a stable crystal is obtained, 258~265°C (decomposition) and an unstable crystal. It is easy to be oxidized in the air when it loses crystal water at 100~120℃ and becomes slightly brown. Density: 1.694g / cm3; Melting point: about 252°C (d...
