Embodiment Construction

[0026] With 1 kg of dried whole herb, the weight loss on drying is ≤15%, that is, after 1000 grams of dried whole herb is baked in an oven at 105°C for 2 hours, the weight is not less than 850 grams. After pulverized by a pulverizer, pass through a 40-mesh sieve, put it into a container with a lid or a reaction kettle, pour 5-7 kg of industrial grade ethyl acetate, soak for 18-28 hours, take the supernatant, and filter it on a filter cloth.

[0027] Continue to add 5 to 7 kg of ethyl acetate, soak for 18 to 28 hours, take the supernatant, and filter it on a filter cloth. After repeating this process for 3 to 5 times, the pressed residue was filtered, the filtrates were combined, and concentrated to obtain 50 to 80 grams of ethyl acetate extract of lingoni.

[0028] Take 20 g of the ethyl acetate extract of Ling vanilla, add 140-220 ml of ethanol containing 95%, heat it up and filter it. Add 1.6 to 7.2 grams of activated carbon and stir for 20 to 30 minutes, then filter, add 1...
