Embodiment 1

[0028] An active extract of apple tree branches, the specific extraction method of the extract is as follows:

[0029] (1) Preparation of antibacterial and antioxidant activity extract of apple tree branches

[0030] Put fresh apple tree branch (200g) into baking oven, dry at 50 DEG C, pulverize, cross 100 mesh sieves, carry out percolation extraction 3 times at room temperature with 70% ethanol by volume percentage, each time 5 hours, filter, obtain the total extract. Distill the total extract to dryness under reduced pressure to obtain the total extract, put the total extract into an ultra-low temperature refrigerator, freeze at -80°C for 4 hours, put it into a freeze dryer for 24 hours, and finally obtain the active extract of apple tree branches (21.3g) .

[0031] (2) the active extract polyphenol content that step (1) obtains is analyzed

[0032] Accurately weigh 0.5000g of pyrogallic acid, put it in a 100mL volumetric flask, dissolve it to the mark, and shake it well....
