The invention relates to the field of disinfectants, provides a plant-derived antibacterial and anti-novel coronavirus SARS-CoV-2 spray and a preparation method of the spray, and overcomes the defects that disinfectants in the prior art are volatile, harmful to human bodies, have potential safety hazards and are poor in disinfection effect when being used in a large scale. The preparation method comprises the following treatment steps: (1) preparing a plant source extract: taking polygonum cuspidatum, senecio scandens, scutellaria baicalensis, radix sophorae flavescentis and golden cypress as raw materials, and respectively extracting a polygonum cuspidatum extracting solution, a senecio scandens extracting solution, a scutellaria baicalensis extracting solution, a radix sophorae flavescentis extracting solution and a golden cypress extracting solution; (2) preparing a nano film-forming agent: taking chitosan with the deacetylation degree of 90%, 2, 3-epoxypropyl trimethyl ammonium chloride and deionized wate
