[0024] Example 1:
[0025] A method for preparing high-purity camellia saponin, the specific steps are as follows:
[0026] 1. Preparation of Camellia oleifera cake powder: first crush the preliminarily screened tea embryos with 10 meshes, and then send them to a decompression digital dryer for drying. The drying temperature is 35°C and the pressure is -40Pa. Then it is sent to the pulverizer for secondary pulverization, and then passed through a 40-mesh sieve to obtain the oil tea cake powder;
[0027] 2. Add 70% ethanol to the camellia cake powder, and adopt continuous countercurrent ultrasonic extraction. Under the ultrasonic effect of the ultrasonic device, the extraction time is 45 minutes once, and the extraction time is 3 times, the extraction temperature is 45℃, and the rotary disc filter is used. , Separate the slag liquid to obtain the medicine slag and the extract respectively;
[0028] 3. Send the medicine dregs to the squeezing machine and drying equipment in turn, carry...

[0035] Example 2:
[0036] A method for preparing high-purity camellia saponin, the specific steps are as follows:
[0037] 1. Preparation of Camellia oleifera cake powder: firstly crush the tea embryos that have been preliminarily screened, and the crushed mesh is 50 meshes, and then they are sent to a decompression digital dryer for drying. The drying temperature is 65°C and the pressure is -60Pa. Then it is sent to the pulverizer for secondary pulverization, and then passed through a 40-mesh sieve to obtain the oil tea cake powder;
[0038] 2. Add 70% ethanol to the oil tea cake powder, and adopt continuous countercurrent ultrasonic extraction. Under the ultrasonic effect of the ultrasonic device, the extraction time is 45 minutes once, and the extraction time is 3 times, the extraction temperature is 60 ℃, and the rotary disk filtration is performed. , Separate the slag liquid to obtain the medicine slag and the extract respectively;

[0046] Example 3:
[0047] A method for preparing high-purity camellia saponin, the specific steps are as follows:
[0048] 1. Preparation of Camellia oleifera cake powder: firstly crush the tea embryos that have been preliminarily screened. The crushed mesh is 30 meshes, and then they are sent to a decompression digital dryer for drying. The drying temperature is 45°C and the pressure is -50Pa. Then it is sent to the pulverizer for secondary pulverization, and then passed through a 40-mesh sieve to obtain the oil tea cake powder;
[0049] 2. Add 70% ethanol to the oil tea cake powder, and adopt continuous countercurrent ultrasonic extraction. Under the ultrasonic effect of the ultrasonic device, the extraction time is 45 minutes once, and a total of 3 extractions are carried out at an extraction temperature of 50℃. , Separate the slag liquid to obtain the medicine slag and the extract respectively;
