An improved method for preparing persimmon leaf extract. Dried persimmon leaves are obtained and are crushed. Ethanol is added to the dried crushed persimmon leaves and ethanol extraction is used to produce a persimmon leaf extraction solution. The persimmon leaf extraction solution is introduced into a concentrator and a first concentrated solution is produced while the ethanol is recycled. The first concentrated solution is filtered to produce a filtrate. The filtrate is introduced into the concentrator to produce a second concentrated solution. The second concentrated solution is repeatedly extracted with ethyl acetate to produce a second persimmon leaf extraction solution. The second persimmon leaf extraction solution is introduced into a concentrator to produce a third concentrated solution while recycling the ethyl acetate. Vacuum drying is used to dry the third concentrated solution to produce a dried persimmon leaf extract.
