[0023] (2) Preparation process
[0024] After the honeysuckle is soaked in water for 30 minutes, decoct it twice for 2 hours each time. Combine the decoction, filter, and concentrate the filtrate to a clear paste with a relative density of 1.22 at 75°C. After cooling, slowly add ethanol to make the alcohol content reach 70 %, stir well, let stand for 12 hours, filter the supernatant, adjust the pH to 7.1 with sodium hydroxide solution, add 75% ethanol to the residue, stir well, let stand for 12 hours, filter, combine the ethanol solution, and recover Ethanol until there is no alcohol taste, add 9 times the amount of water to sediment, filter, concentrate the filtrate, dry under reduced pressure, pulverize into fine powder to obtain honeysuckle extract.
