[0048] [Example 1] Preparation of Chestnut Peel Extract

[0049] 1-1) Preparation of chestnut peel 1,3-butanediol extract

[0050] Utilizing 30% 1,3-butanediol (1,3-butylene glycol), the fruit skin was leached at room temperature for 3 days. Next, filtration was performed sequentially with filters having a size of 250 mesh, 3 μm, 1 μm, and 0.5 μm. Then, after standing at 0 to 4° C. for 3 days, the 1,3-butanediol extract of chestnut skin was obtained by filtering through filters of 0.5 μm, 0.3 μm, and 0.2 μm in order.

[0051] 1-2) Preparation of Chestnut Bark Ethanol Extract

[0052] Using 70% ethanol, the chestnut skin was leached at room temperature for 3 days. Next, filtration was performed sequentially with filters having a size of 250 mesh, 3 μm, 1 μm, 0.5 μm, 0.3 μm, and 0.2 μm. Then, after concentrating the solution at 60° C., vacuum drying was performed at 30° C. for 18 hours to obtain a chestnut peel ethanol extract in a powder form.
