Embodiment 1
[0040] (1) Select the cleaned peanut shells and grind them after drying. After passing through a 40-mesh sieve, take 100g of peanut shell powder, based on powder weight, soak and degrease with 3.7 times of 370g ethyl acetate, and then mechanically stir at room temperature 1 hour, then stand still for 0.5 hour, obtain 470g mixture;
[0041] (2) Filter 470 g of the mixture obtained in step (1), remove the ethyl acetate suspension to obtain peanut shell residue, add 1000 mL of distilled water to the residue, heat to 85° C. in a water bath, and mechanically stir for 3.5 hours to obtain 800 mL of extract;
[0042] (3) The 800mL extract obtained in step (2) was cooled, filtered to remove residue, and then centrifuged at a speed of 3000r / min for 30min to obtain 780mL clarified solution;
[0043] (4) When the 780mL clear solution obtained in step (3) was concentrated under reduced pressure to 1 / 7 volume of the original extract, 200mL of 90% ethanol was added and left overnight;

Embodiment 2
[0046] (1) Select the cleaned peanut shells and grind them after drying. After passing through an 80-mesh sieve, take 100g of peanut shell powder, based on powder weight, soak and degrease with 5 times of 500g ethyl acetate, and then mechanically stir at room temperature 1 hour, then stand still for 0.5 hour to obtain 600g mixture;
[0047] (2) Filter 600 g of the mixture obtained in step (1), remove the ethyl acetate suspension to obtain peanut shell residue, add 800 mL of distilled water to the residue, heat to 90° C. in a water bath, and mechanically stir for 4.5 hours to obtain 810 mL of extract;
[0048] (3) The 810mL extract obtained in step (2) was cooled, filtered to remove residue, and then centrifuged at a speed of 3000r / min for 30min to obtain 790mL clarified solution;
[0049] (4) When the 790mL clear solution obtained in step (3) was concentrated under reduced pressure to 1 / 8 volume of the original extract, 200mL of 90% ethanol was added and left overnight;
