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.

Abstract

The invention provides a preparation method of geutianae anti-irritation factor and a plant extraction device. The preparation method comprises the following steps: smashing the medicinal material, namely, herba geutianae, feeding the smashed medicinal material into the plant extraction device, carrying out aqueous extraction, discharging the aqueous extracted solution and medicinal dregs; and adding a solvent, and carrying out thermal desorption under the condition that inert gas exists, thus obtaining the geutianae anti-irritation factor. The plant extraction device comprises a tank, a top cover and a lower opening cover, wherein the top cover and the lower opening cover are arranged on the top and bottom of the tank, and a ceramic film layer and a carbon fiber layer are arranged in the sequence from outside to inside on each of the inner side wall of the tank and the inner side of the lower opening cover. The preparation method and the plant extraction device have the advantages that extraction and adsorption are carried out at the same time, during the extraction process, the active ingredients are timely transferred into the activated carbon fibers, so that a relatively high concentration gradient is always kept between the extracted liquid and medicinal materials, the extracting ratio is high, and meanwhile, the use amount of the solvent is reduced.

Description

technical field [0001] The invention relates to a preparation method of gentian anti-irritant factor and a plant extraction device, belonging to the technical field of natural product extraction. Background technique [0002] The current anti-irritant ingredients used in cosmetics have a large application market. With the increasingly serious environmental pollution, people's skin is more fragile, and more and more people use cosmetics for a long time to produce irritation. Therefore, almost all formulas need Add anti-irritant ingredients to reduce adverse reactions of products, and plant-derived anti-irritant ingredients are the most popular, but plant-derived anti-irritant ingredients often have weak effects, instability, bad smell, dark color and cannot be consumed Those who accept other shortcomings. [0003] The anti-irritant factor of gentian is prepared from gentian grass, mainly composed of gentiopicroside, swertiamarin, glucoside, trilobatin, bitter glucoside, tetr...
