Embodiment 1

[0049] Preparation of Thanaka Extract:

[0050] S1. Weigh 100g of Tanaka bark, grind it into powder, sieve with 60 meshes, transfer it into a vacuum microwave oven, carry out vacuum microwave pretreatment, keep the vacuum degree at 0.07MPa, the microwave dose at 1.8kw / kg, and the treatment time at 6min. The temperature of the microwave oven cavity was maintained at 180°C to obtain a pretreated product;

[0051] S2. After vacuum microwave pretreatment in step S1, 10 times the volume of 60% ethanol solution was added to the pretreated product, refluxed for 3 hours at 50°C, repeated twice, the extract was collected, concentrated, 50°C Dry, get Tanaka extract.

Embodiment 2

[0053] Preparation of Tanaka Extract:

[0054] S1. Weigh 100g of Tanaka bark, grind it into powder, sieve it with 80 meshes, transfer it to a vacuum microwave oven, carry out vacuum microwave pretreatment, keep the vacuum degree at 0.08MPa, microwave dosage 2.5kw / kg, and process time 8min, Maintain the temperature of the cavity of the microwave oven at 160°C to obtain the pretreated product;

[0055] S2. After vacuum microwave pretreatment in step S1, add 30 times the amount of acetone solution with a volume fraction of 40% to the pretreated product, reflux extraction at 60°C for 4 hours, repeat 4 times, collect the extract, and use 8000 Dal Filtrate through a microfiltration membrane to obtain a refined filtrate. Distill the refined filtrate under reduced pressure with a rotary evaporator, concentrate, and dry at 60°C to obtain a crude extract. Dissolve 1 part of the extract into an aqueous solution with 100 parts of water, and pass through the macropore Resin (D101) was ads...

Embodiment 3

[0057] Preparation of Tanaka Extract:

[0058] S1. Weigh 100g of Tanaka bark, grind it into powder, sieve it with 70 meshes, transfer it to a vacuum microwave oven, and carry out vacuum microwave pretreatment. The cavity temperature of the microwave oven is 170°C, and the pretreated product is obtained;

[0059] S2. After vacuum microwave pretreatment in step S1, add 20 times the amount of ethanol solution with a volume fraction of 50% to the pretreated product, reflux extraction at 55°C for 3.5h, repeat 3 times, collect the extract, and use 5000 channels Distill the refined filtrate under reduced pressure with a rotary evaporator, concentrate, and dry at 60°C to obtain a crude extract. Dissolve 1 part of the extract into an aqueous solution with 100 parts of water, and pass through large Pore ​​resin (D101) was adsorbed and purified, then eluted with absolute ethanol, the eluate was collected, concentrated, and freeze-dried at low temperature to obtain Tanaka extract.
