| titleOfInvention | Preparation method of cyclocarya paliurus leaf extract |
| abstract | The invention relates to the technical field of plant extraction, and discloses a preparation method of a cyclocarya paliurus leaf extract. The preparation method of the invention adopts a high-temperature water extraction method or a low-temperature countercurrent water extraction method to extract cyclocarya paliurus leaves to obtain an extracting solution; performing disc separation on the extracting solution to remove precipitates, concentrating supernate, performing UHT sterilization and filtration to obtain filtrate; and (3) freeze-drying the filtrate, crushing and sieving the dried substance to obtain the cyclocarya paliurus leaf extract. The invention combines the high-temperature water extraction method or the low-temperature countercurrent extraction method with the disc separation, vacuum concentration or reverse osmosis concentration and freeze-drying process, simultaneously optimizes the parameter setting of each process stage, obviously improves the yield of the cyclocarya paliurus leaf extract, and has better fluidity, uniformity, moisture-proof capability and solubility. |
