Embodiment 1

[0016] Embodiment 1: the concentration of extraction solvent (ethanol) is selected

[0017] 1. Take 10 g of the dried and pulverized powder of persimmon stems and leaves, soak it with 100 ml of pure water at room temperature and ultrasonically extract it twice, each time for 60 minutes (500 W), combine the filtrate after filtration, recover the solvent under reduced pressure until dry, and obtain crude persimmon pedicles. Extract; take the obtained persimmon pedicle crude extract and prepare a 0.05mg / ml solution for later use.

[0018] 2. Take 10 g of the dried and pulverized powder of persimmon stalks and leaves, soak it with 100 ml of ethanol solution with a volume concentration of 30% at room temperature and extract it ultrasonically twice, each time for 60 min (500 W). After filtering, combine the filtrates, and recover the solvent under reduced pressure to dryness. , to obtain the crude extract of persimmon pedicle; take the obtained crude persimmon pedicle extract and pr...
