This invention discloses a vitamin preparation stability testing system and method, belonging to the field of preparation testing technology. This invention improves the accuracy and coverage of vitamin preparation stability monitoring, comprehensively capturing complex degradation state changes and stability differences on the preparation surface. It significantly improves the quality assurance efficiency and product reliability level during the vitamin preparation factory testing process. It constructs a dynamic weak point identification mechanism, effectively preventing the omission of weak concentrated areas by fixed-area monitoring, avoiding assessment bias and quality omissions caused by subjective judgment, realizing intelligent allocation and differentiated investment of quality screening resources, effectively improving the pertinence and implementation effect of the deviation batch judgment scheme, identifying concentrated abnormal degradation areas that threaten preparation stability, and ensuring a high degree of consistency between quality control measures and actual degradation failure risks.

The application provides a method for determining the content of biotin in a complex vitamin preparation. The method comprises detecting the content of biotin by high performance liquid chromatography, wherein a surface porous reversed-phase chromatographic column with modified amide groups is used for gradient elution, and a mobile phase A and a mobile phase B are used, the mobile phase A comprises potassium dihydrogen phosphate buffer and acetonitrile, and the mobile phase B comprises acetonitrile. The method can realize the non-interference separation and detection of the content of biotin in the complex vitamin preparation with a complex matrix, and has the advantages of simplicity, good specificity, rapid analysis, accurate result and sensitive response.

The application relates to the technical field of veterinary drugs, and discloses a compound vitamin preparation, a preparation method thereof and application.The compound vitamin preparation comprises a water phase and an oil phase; the water phase comprises the following components in parts by weight: 1-3 parts of hydroxypropyl chitosan, 0.5-2 parts of vitamin C and 50 parts of water; and the oil phase comprises the following components in parts by weight: 1.1-5.5 parts of fat-soluble vitamins and 27.6-41.4 parts of an emulsifying system.The above technical scheme solves the problem that vitamin C in the vitamin preparation in the prior art is easy to be oxidized.

FIELD: veterinary medicine.SUBSTANCE: used in the treatment of purulent inflammation of the base of the skin of the cattle hooves. Orthopedic trimming of the hooves is performed, devitalized tissue is removed, and an orthopedic block is glued to the healthy toe of the animal on the same limb. An even layer of Vet-Kopem ointment is applied to the affected area. The ointment consists of the following components, wt.%: egotsin 20 – 47.6; “АСД-3ф” – 18.9; vitamin preparation Trivit – 14.7; iodinol – 8.2; dioxidine – 4.2; petroleum jelly – 6. Next, the area is covered with a gauze napkin, after which bandage is applied with a veterinary self-fixing elastic bandage. The procedure is repeated after 3-4 days in the first week, and once a week in the following days until local damage to the skin base in the hooves of cattle is completely healed.EFFECT: provision of an increase in the therapeutic effectiveness of the treatment of purulent inflammation of the base of the skin of the hooves of cattle and an enhancement of the antibacterial, antiseptic, and anti-inflammatory effect, resulting in a reduction in the healing time and restoration of the productive performance of animals.1 cl, 2 dwg, 1 tbl
