Low-temperature extraction method for extracting plant active matters by combining high-pressure collision with pressure microfiltration and application of low-temperature extraction method

The invention relates to the technical field of A61K127/00, in particular to a low-temperature extraction method for extracting plant active matter through high-pressure collision combined pressure microfiltration and application thereof.The low-temperature extraction method at least comprises the following steps that 1, plant raw materials are smashed into plant fine powder, an extracting agent is added under the condition of 20-30 DEG C, stirring is conducted for 10-20 min to be uniform, after standing is conducted for 30-60 min, residues are filtered out, and an extracting solution is obtained; (2) putting the extracting solution into a high-pressure extracting device, applying high pressure to fluid by using a high-pressure pump, forming ultra-high-speed fluid by the fluid through a nozzle formed by fine through holes of tens of to hundreds of microns, and collecting the ultra-high-speed fluid into a storage tank; and (3) a plant active ingredient extracting solution is obtained after the material body in
