Embodiment 1
[0076] Take 1 part of sealwort, 3 parts of astragalus, and 1 part of dodder.
[0077] The above three raw materials were crushed and passed through a 10-mesh sieve respectively; water with an amount 3 times the weight of the raw materials was added, and the microwave frequency was 1000MHz, and the stirring frequency was 4r / min, and the extraction was carried out for 35 minutes; the extract was filtered, and the filtrate was concentrated under reduced pressure to Measure the clear paste with a relative density of 1.05 at 80°C; cool down to room temperature, then slowly add an aqueous ethanol solution with a volume percentage concentration of 95% under stirring to reduce the alcohol content to 45%, let it stand for 18 hours, and filter off the supernatant Liquid, recovery of ethanol; vacuum drying to a water content of 3%, that is, the sealwort, astragalus and dodder extract powder.
