[0036] The present invention also provides a wine preparation method. 20000-34000 parts by weight of pretreated grapes are mixed with 50-100 parts by weight of Lycium barbarum, 40-100 parts by weight of Poria cocos, 50-100 parts by weight of Part peanut vine, 50-70 parts by weight Polygonatum, 25-50 parts by weight cinnamon, and 45-60 parts by weight mulberry are mixed for alcohol fermentation, and then prepared after post-fermentation and aging;
[0037] Or carry out alcoholic fermentation to 20000 parts by weight-34000 parts by weight of the pretreated grapes, then through post-fermentation and aging, and then with 50 parts by weight-100 parts by weight of Chinese wolfberry, 40 parts by weight-100 parts by weight of Poria cocos, 50 parts by weight- 100 parts by weight of peanut vine, 50-70 parts by weight of Polygonatum, 25-50 parts by weight of cinnamon, and 45-60 parts by weight of mulberry are mixed and prepared.

Embodiment 1
[0084] Embodiment 1: preparation method of the present invention prepares wine
[0085] 1. Weigh 50 grams each of wolfberry, poria cocos, peanut vine, sealwort, cinnamon, and mulberry, crush them through a 14-mesh sieve, and put them into a Ganymede fermentation tank.
[0086] 2. Get 20Kg of fresh grapes (merlot, cabernet sauvignon, etc.) in addition, first adopt salicylic acid (SA) to spray and process, and then irradiate with ultraviolet (UV) to induce the synthesis of resveratrol in grapes. The specific method is:
[0087] 1), 20Kg of fresh grapes are sprayed with salicylic acid (SA), 100ml of SA solution is sprayed per kilogram of grapes, and the suitable concentration of SA spraying is 100mg / L for Merlot and 60mg / L for Cabernet Sauvignon. Store for 72 hours;
[0088] 2), take out the grapes after the SA spraying treatment, and use ultraviolet (UV) irradiation to induce the synthesis of self-veratrol in the grapes, and the UV induction suitable dose of merlot is 430 seco...
Embodiment 2
[0095] Embodiment 2: determination of resveratrol content
[0096] Sample: trans-resveratrol standard (purity greater than 99%), purchased from Sigma-Aldrich Company.
[0097] Reagents: Methanol and acetonitrile are chromatographically pure, and other reagents are analytically pure.
[0098] Equipment: Waters e2695 liquid chromatograph (equipped with Waters2998 diode array detector and Empower data processing system, Waters, USA); chromatographic conditions: chromatographic column is Ultimate C 18 Column (4.6*250mm, 5μm). Mobile phase A is acetonitrile, mobile phase B is 0.01% phosphoric acid aqueous solution, isocratic elution, A:B=25:75 (v / v). The flow rate was 1.0mL / min, the injection volume was 20μL, the detection wavelength was 306nm, and the column temperature was 35°C.
[0099] Sample treatment: take the wine sample obtained in Example 1 and the commercially available wine sample respectively, centrifuge and concentrate to remove ethanol, add 10 mL of deionized water,...
