[0028] The preparation method of the plant extract composition applicable to androgenetic seborrheic alopecia of embodiment 1-4 comprises the following steps:
[0029] a. Crushing and dissolving: Weigh and dry the above-mentioned various raw materials according to parts by weight, pulverize and pass through a 200-mesh sieve, and dissolve with a concentration of 20-80% ethanol as a solvent. The weight ratio of raw materials to solvent is 1: 3~1:10;
[0030] b. Low-temperature and high-pressure-difference extraction: the mixture obtained in step a is obtained in a low-temperature environment of 5-50°C by instantaneously generating a pressure difference to cause the plant cells of the compound to be broken, and the active ingredient overflows to come into contact with the solvent;
[0031] c. Multi-stage membrane filtration: Among them, the filtration temperature is 14-20°C, the pressure is 0.02-0.1mPa, the flow rate is 1.5-3 LPM, and the motor frequency is 45-50Hz.
