Embodiment 1

[0060] A plant extract, consisting of 10 parts by weight of nasturtium extract, 12 parts by weight of gallnut extract, 15 parts by weight of persimmon leaf extract, and 0.5 parts by weight of additives;

[0061] The preparation of described nasturtium extract is as follows:

[0062] S1. Wash and dry the nasturtium raw material, crush it through a 300-mesh sieve, and obtain the nasturtium powder;

[0063] S2. Take 50 parts by weight of nasturtium powder, add 500 parts by weight of 1mol / L sodium hydroxide aqueous solution, and extract under reflux for 3 times at 80° C., extract for 1 hour each time, cool, and filter to obtain filter residue and alkaline water extract;

[0064] S3. Take all the filter residues in S2, add 500 parts by weight of 60wt% ethanol aqueous solution, reflux extraction at 60°C for 3 times, each time for 1h, and cool and filter to obtain an ethanol extract;

[0065] S4. After adjusting the pH value of the alkaline water extract to neutrality with 2mol / L hy...

Embodiment 2

[0091] It is basically the same as Example 1, except that a selenium-enriching agent is added during the preparation of the persimmon leaf extract.

[0092] The preparation method of the persimmon leaf extract is as follows:

[0093] X1, wash and dry the persimmon leaves, and pass through a 150-mesh sieve to obtain the persimmon leaf powder;

[0094] X2. Take 50 parts by weight of persimmon leaf powder, add 800 parts by weight of deionized water and mix evenly, heat to 90°C, stir and extract at 600rpm for 6h, filter to obtain a primary filtrate and a primary filter residue, and the primary filter residue is 1g according to the solid-liquid ratio: Add 5mL into 60wt% ethanol aqueous solution, heat to 70°C, stir at 600rpm for 4h, filter to obtain the secondary filtrate and secondary filter residue, combine the primary filtrate and the secondary filtrate, and store in a vacuum of -0.04MPa and a water bath temperature of 70°C Concentrate under reduced pressure to 1 / 10 of the total...

Embodiment 3

[0103] It is basically the same as Example 2, except that the fermenting bacteria is Lactobacillus reuteri.
