Honeysuckle contains abundant components such as volatile oil, flavonoids and organic acids, playing the role of antibiosis, antivirus, antiphlogosis, immunopotenfiation and antioxidation. The active ingredients and pharmacological action of honeysuckle are reviewed in the paper, so as to lay the foundation for further application of honeysuckle in veterinary clinic.展开更多

The HPLC system consisted of Stable Bond - C18 column （4.6 × 150 mm, 5um） and with a mobile phase of acetonitrile -0.05mol/L potassium dihydrogen phosphate solution （50：50,v：v） mixture. Berberine hydrochloride was detected at the wavelength of 345 nm, with a flow rate of 1.0 ml/min and a column temperature of 30 ℃. The excipients and solvents in the granule could be well separated from the drug under such a designated chromatogram condition and did not interfere with the assay. A good linear relationship was found between peak area and the concentration of berberine hydrochloride in the range of 16.0 -48.0 I^g/mL. The average recovery of berberine hydrochloride was 99.09%. The established approach was specific, accurate, reliable, prompt, sensitive and applicable, and could be used to control the quality of Qingwen Baidu granule.展开更多

The veterinary medicines can cause various kinds of harmful impact to the environment. Now the relevant research has been a hot all over the world. With the feces excreted to the environment, the veterinary medicines can be accumulated in the soil and water, and produce all sorts of reaction. Some medicines can cause toxic effect to animals, plants and microorganisms. The article summarized the residue, the environmental impact, the transformation and the development direction of the veterinary medicine in the environment to supply frame of reference for further research.展开更多

[Method] High per- formance liquid chromatography （HPLC） method was used to determine the contents of sulfamonomethoxine sodium and trimethoprim simultaneously in compound sulfamonomethoxine sodium propolis solution. [Result] Sulfamonomethoxine sodium and trimethoprim showed a linear relationship within the concentration of 10 - 500 μg/mL under the following chromatographic conditions： Kromasil C18 column （250 mm × 4.6 mm, 5 μm）, mobile phase 0.02 mol/L phosphoric acid solution- methanol（80：20, V/V）, detection wavelength 270 nm, flow rate 1.0 mL/min, and column temperature 30℃. The average recoveries were 99.3% and 99.4%, respectively. [ Conclusion] The method is accurate and feasible, and can determine sulfamonomethoxine sodium and trimethoprim simultaneously in compound sul- famonomethoxine sodium propolis solution.展开更多
