| titleOfInvention | Method for extracting cactus glycoside |
| abstract | The invention relates to an extraction method for extracting cactus glycoside from cactus. In particular to an extraction method adopting an enzyme method-microwave wall breaking method. The processing steps comprise: drying radix et caulis Opuntiae Dillenii, and pulverizing in a pulverizer to obtain radix et caulis Opuntiae Dillenii coarse powder; weighing a certain amount of coarse powder, adding a citric acid-disodium hydrogen phosphate buffer solution with a pH value of 4.5 according to a material-liquid ratio of 1:5, uniformly mixing, adding 15% of cellulase according to the mass, carrying out enzymolysis for 1h at 55 ℃, centrifuging for 10min at 4000r/min, collecting supernatant, taking a proper amount of enzyme-method wall-broken precipitate, adding warm water, 50-60% of absolute ethyl alcohol and 0.05mol/L of citric acid-disodium hydrogen phosphate buffer solution with a pH value of 3.7 according to the material-liquid ratio of 1:5 respectively, extracting for 30-40 min, carrying out microwave-assisted extraction under the same condition, centrifuging for 10min at 4000r/min after the extraction is finished, taking supernatant, combining the two supernatants, and drying at 60 ℃ to obtain the cactus glycoside. Compared with the traditional extraction method, the method has the advantages of simple operation, short time and less decomposition of unstable substances. |
