[0031] The preparation method of this natural antibacterial spray comprises the following steps:
[0032] (1) Preparation of chitosan oligosaccharides: choose chitosan with a degree of deacetylation of 85-95% and add it into water to stir and dissolve to obtain a chitosan solution, adjust the temperature of the solution to 40-65°C and use sodium citrate buffer to When the pH value of the solution is adjusted to 4.0 to 6.8, a solution containing chitosan enzyme is added to the chitosan solution for enzymatic reaction, and the volume ratio of the solution containing chitosan enzyme added to the chitosan solution is 1 :40, reacted for 6 to 18 hours, adopted gel permeation chromatography to separate and purify the product of the enzymatic reaction, and then obtained chitosan oligosaccharide through sublimation drying;
[0033] (2) Preparation of Comfrey Extract: Using ethanol Soxhlet extraction method to extract Comfrey, the concentration of ethanol used is 60-80%, the consumption...

[0039] One, the preparation of this natural antibacterial spray:
[0040]Take prepared 0.25 g of chitosan oligosaccharide and 0.3 g of berberine in a 200 ml beaker, add 20 ml of distilled water, stir and heat to dissolve, and after dissolving, a mixed solution containing chitosan oligosaccharide is obtained; Put 6 grams of comfrey extract into a 100 ml beaker, add 50 ml of dehydrated alcohol to the beaker, stir after the comfrey extract in the beaker dissolves, then add 0.75 milliliters of laurocapram in the beaker, and The solution was mixed to obtain a mixed solution containing the comfrey extract; the mixed solution containing the comfrey extract was poured into the mixed solution containing chitosan oligosaccharide, and 4 drops (about 0.2 ml) of tea tree essential oil were added dropwise while stirring, and then Distill water until the volume of the mixed solution reaches 100 milliliters and then transfer it to a butane spray tank to prepare the natural antibacterial spray...
