example 1
[0051] [Example 1] Preparation of Zihua Diding Juice
[0052] In water (extraction solvent), add its total weight 0.1wt% pectinase (available from Novozymes, model Novozymes L), and then add the powder ground from the whole plant of Viola chinensis (origin: China) into the water containing pectinase (wherein the weight ratio of water: Viola chinensis powder is 30:1), make it mix Then raise the temperature of this liquid to and maintain at 55±5°C, and keep soaking for about 60 minutes to carry out the first stage of extraction. Then, the temperature of the liquid was raised to and maintained at 85±5° C. for about 30 minutes to carry out the second-stage extraction.
[0053] After the heating was stopped, the extraction solvent was filtered through a 400-mesh sieve to remove solids to obtain a supernatant. Concentrate the supernatant under reduced pressure at 60±5°C with a concentrator (purchased from BUCHI, model Rotavapor R-100) until the Brix value (Degrees Brix) of the so...

[0054] [Example 2] Total flavonoid content test
[0055] After diluting the viola extract obtained in Example 1 with water 10 times according to its volume, take 200 μL into a test tube. Add 200 μL of 5wt% sodium nitrite (purchased from Sigma, product number 31443) aqueous solution into this test tube, mix well and let stand for reaction for 6 minutes. Then add 200 μL of 10wt% aluminum nitrate (purchased from Alfa Aesar, product number 12360) aqueous solution, mix well and let stand for reaction for 6 minutes, then add 2 mL of 4wt% sodium hydroxide aqueous solution (sodium hydroxide is purchased from Macron, product number 7708-10 ) to make it evenly mixed. Finally, add 1.4 mL of water to the test tube and mix evenly to obtain the reaction solution. Take 200 μL of the reaction solution in the test tube to a 96-well reaction plate, and use a spectrophotometer (Jasco, model V-730) to detect the absorbance at a wavelength of 500 nm. .
[0056] Standards are then prepared to cr...

[0059] [Example 3] Total polyphenol content test
[0060] After diluting the viola extract obtained in Example 1 with water 10 times according to its volume, take 100 μL into a test tube. Then, add 500 μL of Folin-Ciocalteu's phenol reagent (Folin-Ciocalteu's phenol reagent, purchased from Merck, product number 1.09001.0100) to this test tube, mix well and let stand for 3 minutes, then add 400 μL of 7.5wt% sodium carbonate (purchased from Sigma, commodity number 31432) aqueous solution in test tube, make it mix uniformly and react for 30 minutes. After ensuring no air bubbles in the solution by vortex, 200 μL of the solution was taken to measure the absorbance at a wavelength of 750 nm.
[0061] Next, prepare a standard to create a calibration curve. In this case, gallic acid (Gallic acid) equivalent is used as the expression of the relative content of total polyphenols. Here, prepare 0 μL / mL, 20 μL / mL, 40 μL / mL, 60 μL / mL, 80 μL / mL, and 100 μL / mL standard solutions of galli...
