Embodiment 1
[0044] This embodiment relates to a preparation method of gentian anti-irritant factor, comprising the following steps:
[0045] Grind gentian to 80 mesh, put it in the aforementioned plant extraction device, add 5 times of water for extraction, the time is 1.5h, the stirring speed is 400 rpm, and the circulation rate is 5 times / h. The solution and dregs are released together, add 4 times the amount of 50wt% propylene glycol aqueous solution, desorb at 95°C for 3 hours, the stirring speed is 500 rpm, the circulation rate is 8 times / h, and 2 times the amount of liquid / h is introduced during the period Nitrogen gas, after the desorption process is finished, the compressed air is fed to make the extract liquid flow out completely.
Embodiment 2
[0047]This embodiment relates to a preparation method of gentian anti-irritant factor, comprising the following steps:
[0048] Grind gentian to 20 mesh, place it in the aforementioned plant extraction device, add 3 times of water for extraction, the time is 3 hours, the stirring speed is 100 rpm, and the circulation rate is 3 times / h. Release together with medicinal dregs, add 2 times the amount of 30wt% propylene glycol aqueous solution, desorb at 70°C for 1.5 hours, stir at 300 rpm, and circulate at 5 times / h, during which time 4 times the amount of liquid is introduced / h The helium gas, after the desorption process is completed, the compressed air is introduced to make the extracting solution flow out completely, that is to say.
