150 results about "Lincomycin-B" patented technology

Lincomycin is a lincosamide antibiotic that comes from the actinomycete Streptomyces lincolnensis. A related compound, clindamycin, is derived from lincomycin by using thionyl chloride to replace the 7-hydroxy group with a chlorine atom with inversion of chirality.

Method for simultaneously detecting multi-kind pesticide residues in bee products

InactiveCN101358953ASolve the problem of matrix effectFast wayComponent separationRetention timePhosphate
The present invention relates to a method of simultaneously detecting a plurality of agro-veterinary drug residues in bee products. The extracted liquid trichloroacetic acid or perchloric acid and the extracted liquid acetate, phosphate or borate solution are added into a sample; the pH value is controlled between 4.5 and 9.0; the mixed solution is centrifuged, the filtrate is added into a solid phase extraction column to be extracted, the extraction column is eluted and dried, the column is washed by oxalic acid-methanol solution, the volume of the eluent is defined by the aqueous solution of methanol, the eluent is added into liquid chromatography-tandem mass spectrometry to be analyzed and tested, the acquired chromatographic peak is contrasted with the known standard chromatographic peak of the drug, and according to the retention time and the abundance of the mass spectrum ions, the specific name of the detected drug is determined. The method only requires one pre-treatment of the sample, and thus can simultaneously extract 11 classes and more than 60 kinds of veterinary drug residues, such as sulfonamides, quinolones, macrolides, lincomycins, nitroimidazoles, beta-lactams, tetracyclines, chloromycetins, trinethoprims, chlordimeform, triadimenol and the like, the efficiency of analysis is high, and the detection cost is greatly reduced.

Coal water slurry made by combining lincomycin wet bacteria slag and coal

The invention relates to a coal water slurry combined by a lincomycin wet bacteria slag and coal which effectively settles the application of the lincomycin wet bacteria slag and prevents the pollution problem to environment. The settled technical scheme comprises the following steps: the coal water slurry is prepared by the lincomycin wet bacteria slag, a coal dust, an additive agent and water, wherein the weight ratio of the lincomycin wet bacteria slag and the coal dust is: 5-501f lincomycin wet bacteria slag, 50-951253232014f coal dust, then sum of the lincomycin wet bacteria slag and coal dust is 50-70, the additive agent is 0. 1-5and water balance by weight percentage, firstly the additive agent, water and lincomycin wet bacteria slag are mixed and stirred to a uniform mixture solution, then the coal dust is added in the mixture solution to mix uniformly and the coal water slurry with a mass concentration of 50-70 ontaining the lincomycin wet bacteria slag and the coal dust is obtained. The coal water slurry has simple component and low cost, and is easy to produce. The incomycin wet bacteria slag is fully used, not only the novel fuel source is solved and a great deal of coal is saved, but also the pollution to environment by incomycin wet bacteria slag is prevented. The coal water slurry of the invention has a huge economy and social benefit.

Method for extracting lincomycin by using resin to adsorb fermentation stock solution

The invention discloses a method for extracting lincomycin lincomycin by using resin to adsorb a fermentation stock solution. The method comprises the following steps: (1), placing a fermentation solution in a pretreatment tank, adding a sodium hydroxide solution whiling stirring, heating, adding resin and stirring slowly to obtain filtered resin; (2) placing the filtered resin into alkaline water with the same volume, and adding deionized water to clean the resin; (3), placing the cleaned resin in a chromatographic column and eluting the resin with n-butyl alcohol; (4), taking lincomycin desorbed solution and adding activated carbon for decolorizing; (5) desalinating the decolorized liquid through a desalinating column to obtain lincomycin desalinating liquid; (6), concentrating; (7) drying to obtain the finished product of hydrochloric acid lincomycin. The method provided by the invention avoids the procedures of plate-frame pressure filtration or ceramic membrane filtration, solvent extraction, back extraction and the like in the traditional process, and has the advantages of being simple in operation, low in labor intensity, clean in working environment, simplified in process, small in occupied area, low in cost and small in environmental pollution; the total recovery is greater than 85%, and the purity of the finished product is greater than 98%.

Preparation method of lincomycin hydrochloride injection

The invention provides a preparation method of lincomycin hydrochloride injection, which comprises the following steps: (1) fetching 20,000ml of injection water, 6kg of lincomycin hydrochloride raw powder, 8g of EDTA (ethylenediamine tetraacetic acid)-2Na, 172g of anhydrous sodium bicarbonate and appropriate hydrochloric acid and anhydrous sodium bicarbonate for later use; (2) soaking a reaction kettle, a conveying pipeline and a constant-temperature water supply system with EDTA, and flushing for later use; (3) leading the stored injection water into a water storage tank, and connecting the water storage tank with a water outlet pipe through a pipeline; (4) injecting the injection water into the reaction kettle through the water outlet pipe, adding the lincomycin hydrochloride raw powder, and dissolving; (5) adding the anhydrous sodium bicarbonate into the solution after ultrafiltration to adjust the pH value, adding EDTA-2Na, sufficiently stirring, and then measuring the content; (6) if the liquid medicine is qualified, filling in a hundred-class environment to obtain the lincomycin hydrochloride injection. According to the method provided by the invention, the content of a lincomycin component B is effectively reduced in order to improve the quality of the lincomycin hydrochloride injection and reduce the preparation cost.

Dilute solution used for preserving racoon dog seminal fluid at normal temperature, and semen collection method

The invention discloses a dilute solution used for preserving racoon dog seminal fluid at normal temperature, and a semen collection method. The dilute solution comprises following ingredients: 36 to 38g of glucose, 1.20 to 1.30g of sodium bicarbonate, 1.20 to 1.30g of ethylene diamine tetraacetic acid, 5.50 to 6.30g of sodium citrate, 0.65 to 0.85g of potassium chloride, 0.50 to 3.05g of bovine serum albumin, 0.05 to 0.30g of acetylcysteine, 0.50 to 1.20g of penicillin, 0.30 to 1.00g of streptomycin, 0.05 to 1.50g of lincomycin and 0.01 to 0.05g of spectinomycin; and a mixture of the ingredients above is diluted to 1000ml by adding triple-distilled water so as to obtain the dilute solution. Key steps of the semen collection method are that: female racoon dogs in heat are used as dummy teaser; conditioned reflex of male racoon dogs to artificial semen collection is formed by training; the training is repeated for 3 to 4 times until conditioned reflex is formed; and then the female racoon dogs are replaced by a female racoon dog-simulated dummy teaser which is filled with urine of female racoon dogs in heat so as to collect male racoon dog semen. The dilute solution and the semen collection method can be used for collecting racoon dog semen, diluting for preservation, realizing artificial insemination and obtaining offspring; and are capable of promoting the popularization of racoon dog artificial insemination technologies, and increasing economic benefits of racoon dog industry.
