Problems solved by technology

[0003] For a long time, Yaonong planted Chrysanthemum chrysanthemum only to take its flowers, and the stems and leaves, which accounted for more than 80% of the plant weight of Chrysanthemum chrysanthemum, were often discarded (burned) as waste, which not only caused waste of natural resources, but also easily caused environmental (atmospheric) pollution. )Pollution
At present, there are very few studies on the extraction and application of antibacterial components from the stems and leaves of Chrysanthemum chrysanthemum

Embodiment 1

[0025] Embodiment 1: Preparation of Chrysanthemum chrysanthemum stem and leaf extract

[0026] (1) Pre-treatment: Clean the stem and leaf samples of Chrysanthemum chrysanthemum, dry them in an oven at 55°C to constant weight, crush them with a pulverizer, and pass them through a 100-mesh sieve to obtain medicinal material powder. Store the medicinal powder in a blue bottle for future use.

[0027] (2) Extraction: Weigh 10g of the dried medicinal material powder obtained in step (1), add 100mL of ethanol with a volume percentage of 75% (i.e., the ratio of solid to liquid is 1:10), soak overnight, reflux in a water bath at 90°C for 4h, and suction filter . Obtain medicinal material filtrate and medicinal residue.

[0028] (3) The medicinal residues were repeatedly extracted three times according to the conditions in step (2).

[0029] (4) Combine the medicinal material filtrate obtained in steps (2) and (3). After spinning off the ethanol solvent in the medicinal material fi...
