Embodiment 1
[0271] Preparation method of theabrownin component:
[0272] Add 10 times the amount of water to leaching Pu’er tea at 80°C for three times, each time for 0.5-1 hour, combine the extracts below 70°C and concentrate under reduced pressure to a relative density of 1.05-1.10, add 95% ethanol to sink to 80%, and statically reach 12 After more than 1 hour, the alcohol precipitate is vacuum-dried under reduced pressure to obtain the crude product of theabrownin, which is redissolved in water and filtered, and the filtrate is concentrated under reduced pressure to dryness below 70°C to obtain the theabrownin component;
[0273] Preparation method of tea polyphenol component:
[0274] Add 10 times the amount of water to leaching Pu’er tea at 80°C for three times, each time for 0.5-1 hour, combine the extracts below 70°C and concentrate under reduced pressure to a relative density of 1.05-1.10, add 95% ethanol to sink to 80%, and statically reach 12 After more than 1 hour, the superna...
Embodiment 2
[0279] Preparation method of theabrownin component:
[0280] Add 10 times the amount of water to Pu’er tea and extract it once at 80°C for 0.5 hours, concentrate the extract under reduced pressure below 70°C to a relative density of 1.05-1.10, add 90% ethanol to sink to 70% alcohol content, and settle to 12 After more than 1 hour, the alcohol precipitate is vacuum-dried under reduced pressure to obtain the crude product of theabrownin, which is redissolved in water and filtered, and the filtrate is concentrated under reduced pressure to dryness below 70°C to obtain the theabrownin component;
[0281] Preparation method of tea polyphenol component:
[0282] Add 10 times the amount of water to Pu’er tea and extract it once at 80°C for 0.5 hours, concentrate the extract under reduced pressure below 70°C to a relative density of 1.05-1.10, add 90% ethanol to sink to 70% alcohol content, and settle to 12 After more than 1 hour, the supernatant was obtained, and the crude product w...
Embodiment 3
[0287] Preparation method of theabrownin component:
[0288] Add 10 times the amount of water to Pu’er tea and extract at 80°C for 2 times, each time for 1 hour, concentrate the extract under reduced pressure below 70°C to a relative density of 1.05-1.10, add 100% ethanol until the alcohol content is 80%, and let it stand for 12 hours Above, the alcohol precipitate is vacuum-dried under reduced pressure to obtain the crude product of theabrownin, which is redissolved in water and filtered, and the filtrate is concentrated under reduced pressure to dryness below 70°C to obtain the theabrownin component;
[0289] Preparation method of tea polyphenol component:
[0290] Add 10 times the amount of water to Pu’er tea and extract at 80°C for 2 times, each time for 1 hour, concentrate the extract under reduced pressure below 70°C to a relative density of 1.05-1.10, add 100% ethanol until the alcohol content is 80%, and let it stand for 12 hours Above, get the supernatant, concentrat...
