Embodiment 1

[0035] (1) Dried hawthorn 1kg, placed in a microwave-assisted extraction equipment and heated to a surface temperature of 60°C.

[0036] (2) After taking it out, add distilled water to reflux at a ratio of 1:2.5, filter and separate, and let the filtrate stand for more than 24 hours for later use.

[0037] (3) Dry distill the filtered solid-phase hawthorn at 250°C until there is no distillate, redistill the dry distillate at 80°C to 180°C in an oil bath, and let the redistillate stand for more than 24 hours for later use.

[0038] (4) Take the liquid in (2) and the liquid in (3) and mix them at a ratio of 2:1, and age them under reflux for 1 hour.

[0039] (5) Filtrate the obtained liquid, adjust the pH value to 4.0-5.0 with sodium hydroxide solution (0.5mol / l-1mol / l), filter after 24 hours, add 2% Tween-80, potting, 100°C-120°C Underflow steam sterilization for 10 to 30 minutes, about 1L of the breast injection of the present invention is obtained.

Embodiment 2

[0041] (1) Dried hawthorn 1kg, placed in a microwave-assisted extraction equipment and heated to a surface temperature of 60°C.

[0042] (2) After taking it out, add distilled water to reflux at a ratio of 1:2.5, filter and separate, and let the filtrate stand for more than 24 hours for later use.

[0043] (3) Dry distill the filtered solid-phase hawthorn at 250°C until there is no distillate, redistill the dry distillate at 80°C to 180°C in an oil bath, and let the redistillate stand for more than 24 hours for later use.

[0044] (4) Take the liquid in (2) and the liquid in (3) and mix them at a ratio of 1:1, and age them under reflux for 1 hour.

[0045] (5) Filtrate the obtained liquid, adjust the pH value to 4.0-5.0 with sodium hydroxide solution (0.5mol / l-1mol / l), filter after 24 hours, add 1%-2% Tween-80, potting, 100°C Circulating steam sterilization at ~120° C. for 10 to 30 minutes to obtain about 700 ml of the breast injection of the present invention.

Abstract

A process for preparing the breast injection from haw to treat the mammitis of cow includes such steps as reflux extracting in alcohol solution, concentrating the liquid to obtain extract, dry distillation and redistillation of dregs to obtain distilled liquid, proportionally mixing it with said extract, ageing, regulating pH value with sodium hydroxide, filtering, and sterilizing by steam.

Description

technical field [0001] The invention relates to a process for preparing breast injection. Background technique [0002] The active ingredient extracted and separated from hawthorn by the preparation method provided by the invention has a broad-spectrum bactericidal function, and has a strong inhibitory effect on Staphylococcus aureus, Streptococcus and the like. The in vitro antibacterial test proves that compared with antibiotics, the bactericidal ability of this product is only slightly weaker than that of penicillin and has stronger antibacterial function. In the minimum inhibitory concentration (MIC) test, this product still has antibacterial function when diluted to 64 times. Bovine mastitis is caused by a variety of non-specific pathogenic microorganisms, most of which are caused by Staphylococcus and Streptococcus. The method of treating bovine mastitis is currently the local injection of antibiotics, which causes problems such as tolerance and antibiotic residues i...
