Embodiment 1

[0021] The preparation method of mung bean extract is as follows:

[0022] 1) Take mung bean powder, add 10 times water by weight, heat to a constant temperature of 50-60℃ for 2 hours, grind and filter, then rinse the filter residue with 5 times water, discard the filter residue, combine the filtrate, and settle for 4 hours. Filtering, taking the solid matter and drying to obtain mung bean starch extract, and the filtrate is used for later use. The mung bean starch extracted species contains 50-99% mung bean starch by weight;

[0023] 2) Concentrate the filtrate under reduced pressure to a relative density of 1.02-1.08 (measured at 20°C), add 95% ethanol to the concentrate until the ethanol concentration reaches 40%, refrigerate at 4°C, settle for 9 hours, filter, and concentrate the filtrate , Dry, to obtain mung bean total flavonoid extract, said mung bean total flavonoid extract contains 20-60% by weight of total flavonoids;

[0024] 3) The dried mung bean starch extract and the ...

Embodiment 2

[0026] 1) Take mung bean powder, add 15 times of water by weight, heat to a constant temperature of 50-60°C for 4 hours, grind and filter, then rinse the filter residue with 10 times of water, discard the filter residue, combine the filtrate, and settle for 8 hours. Filtering, taking the solid matter and drying to obtain mung bean starch extract, and the filtrate is used for later use. The mung bean starch extract species contains 50-99% mung bean starch by weight;

[0027] 2) Concentrate the filtrate under reduced pressure to a relative density of 1.02-1.08 (measured at 20°C), add 95% ethanol to the concentrate until the ethanol concentration reaches 70%, refrigerate at 4°C, settle for 15 hours, filter, and concentrate the filtrate , Dry, to obtain mung bean total flavonoid extract, said mung bean total flavonoid extract contains 20-60% by weight of total flavonoids;

[0028] 3) The dried mung bean starch extract and the mung bean total flavonoid extract are mixed uniformly to obt...

Embodiment 3

[0030] 1) Take mung bean powder, add 12 times of water by weight, heat to 50-60℃ for 3 hours, grind and filter, then rinse the filter residue with 8 times water, discard the filter residue, combine the filtrate, and settle for 6 hours. Filter, take the solid matter and dry to obtain the mung bean starch extract, and the filtrate will be used for later use;

[0031] 2) Concentrate the filtrate under reduced pressure to a relative density of 1.05 (measured at 20°C), add 95% ethanol to the concentrate until the ethanol concentration reaches 60%, refrigerate at 4°C, settle for 12 hours, filter, take the filtrate, concentrate, and dry , Get the total flavonoids extract of mung bean;

[0032] 3) Mix the mung bean starch extract and the mung bean total flavonoid extract evenly.
