Embodiment 1
[0036] (1) Take Semen jujuba, remove impurities, foreign matter and non-medicinal parts;
[0037] (2) Stir-frying: Put the clean wild jujube kernels in a preheated drum-type medicine frying machine, control the temperature at 110°C, and fry for 15 minutes until the surface is slightly swollen, slightly burnt, and has a slight burnt aroma. Take it out and let it cool until room temperature;
[0038] (3) Crushing and degreasing: Properly crush the roasted Chinese jujube kernels (through No. 1 sieve, 10 mesh), and then use supercritical CO 2 The extraction temperature is 65°C, the extraction pressure is 28Mpa, CO 2 The flow rate is 8.4L / h, and the time is 40min, and the coarse powder of jujube seed is obtained;
[0039] (4) drying: carry out vacuum-drying with wild jujube seed coarse powder, temperature is 50 ℃, after controlling water content 8%, stop drying;
[0040] (5) Pulverization: Put the prepared wild jujube kernel powder into a superfine pulverizer, make the outer jac...
Embodiment 2
[0043] The difference between this embodiment and embodiment 1 is: the supercritical CO of step (3) 2 In the extraction step, the supercritical extraction temperature is 60°C, the extraction pressure is 24Mpa, CO 2 The flow rate is 8.4L / h, and the time is 40min.
Embodiment 3
[0045] The difference between this example and Example 1 is: in the pulverizing step of step (5), pulverize for 2 to 3 minutes, and finally pulverize into jujube seed powder with an average particle size of 30 μm.
