Embodiment 1
[0039] Take 50kg of papaya decoction pieces, put them into the extraction tank, add 1.0% cellulase for enzymolysis, control the enzymolysis temperature at 58°C, and enzymolysis for 6 minutes; put the precipitate separated after enzymolysis into the extraction tank , add 500L of 50% ethanol to reflux and extract 3 times, each time for 2 hours, combine the extracts, recover the ethanol under reduced pressure until there is no alcohol smell, put it on a D-3520 macroporous adsorption resin column, and fully elute with water until the effluent is clear and After no reducing sugar reaction, elute with 60%, 70%, and 80% ethanol respectively, collect 60%, 70%, and 80% ethanol eluate, concentrate under reduced pressure and have no alcohol smell, filter, and add 10% hydrogen Sodium oxide solution adjusts the pH value to 9.0, adds 2 times the amount of water-saturated n-butanol to extract twice, combines the n-butanol solution, concentrates under reduced pressure to nearly dryness, and dr...
Embodiment 2
[0041] Take 50kg of papaya decoction pieces, put them into the extraction tank, add 1.0% cellulase for enzymolysis, control the enzymolysis temperature at 55°C, and enzymolysis for 10 minutes; put the precipitate separated after enzymolysis into the extraction tank , add 500L of 70% ethanol to extract 3 times, 2 hours each time, combine the extracts, recover the ethanol under reduced pressure until there is no alcohol smell, put it on the XAD-2 macroporous adsorption resin column, and fully elute with water until the effluent is clear and free of alcohol. After reducing sugar reaction, elute with 60%, 70%, 80% ethanol, collect 60%, 70%, 80% ethanol eluate, concentrate under reduced pressure without alcohol smell, filter, add 10% sodium hydroxide Adjust the pH value of the solution to 8.0, add 1 times the amount of water-saturated n-butanol to extract three times, combine the n-butanol liquid, concentrate under reduced pressure to nearly dryness, and dry under reduced pressure t...
Embodiment 3
[0043] Take 50kg of papaya decoction pieces, put them into the extraction tank, add 1.0% cellulase for enzymolysis, control the enzymolysis temperature at 52°C, and enzymolysis for 15 minutes; put the precipitate separated after enzymolysis into the extraction tank , add 500L 80% ethanol to reflux extraction 3 times, each time for 2 hours, combine the extracts, recover the ethanol under reduced pressure until there is no alcohol smell, put it on the XAD-4 macroporous adsorption resin column, and fully elute with water until the effluent is clear and free of alcohol. After reducing sugar reaction, elute with 60%, 70%, 80% ethanol, collect 60%, 70%, 80% ethanol eluate, concentrate under reduced pressure until no alcohol smell, filter, add 10% potassium hydroxide The pH of the solution is adjusted to be 9.0, add 2 times the amount of water-saturated n-butanol to extract twice, combine the n-butanol solution, concentrate under reduced pressure to nearly dryness, and dry under reduc...
