[0004] Patent CN 102977162 A "A Production Method of High-Purity Tea Saponin" discloses a method for extracting high-purity tea saponin from tea seed dregs by using ethanol ultrasonic extraction combined with macroporous resin purification technology. The content of tea saponin is greater than 90%, but it takes a long time to purify with macroporous resin and the yield is low, which limits the wide application of this method
Patent CN 104945463 A "A Method for Extracting Tea Saponin" discloses a method for extracting high-purity tea saponin from tea seed dregs by using small molecule alcohol heating extraction combined with sitosterol complex precipitation purification technology. The content of tea saponin in the extract is as high as 98%, but the extraction rate of this method is only 30%, and the production cost is high, which also limits the wide application of this method

Embodiment 1

[0019] Take a certain amount of choline chloride and glycerin and mix them according to the molar ratio of 1:2, stir and heat at 80°C and 500rpm / min for 1 hour, and form a uniform and transparent deep eutectic reagent; put the tea seed meal under vacuum at 65°C After being dried in a drying oven, it was pulverized by a traditional Chinese medicine pulverizer and passed through a 60-mesh sieve to further pulverize into cell-level ultrafine powder. Take 5.0kg tea seed cell-level ultrafine powder and 45% ethanol-0.25 sodium sulfate salt solution two-phase system to press After mixing at a mass-to-volume ratio of 1:10, centrifuge at 400W ultrasonic power, 200W microwave power, and 35°C for 40 minutes to obtain the supernatant, and then extract the residue three times with ethanol-salt two-phase aqueous phase and combine it. For the supernatant, add 25% choline chloride-glycerol deep eutectic reagent into the supernatant, vortex for 20s, and then centrifuge, separate the phases of t...

Embodiment 2

[0021] Mix a certain amount of betaine and glycerin in a molar ratio of 1:2, stir and heat at 80°C and 600rpm / min for 2 hours, and form a uniform and transparent deep eutectic reagent; place the tea seed meal in a vacuum oven at 60°C After medium-drying, pass through a 60-mesh sieve after being pulverized by a traditional Chinese medicine pulverizer to further pulverize into cell-level ultrafine powder, take 5.0kg tea seed cell-level ultrafine powder and 45% ethanol-0.35 sodium citrate aqueous two-phase system by 1 : After mixing with a mass volume ratio of 12, microwave-ultrasound at 500W ultrasonic power, 150W microwave power and 40°C for 35 minutes and then centrifuge to obtain the supernatant. solution, add 25% betaine-glycerol deep eutectic reagent into the supernatant, vortex for 20s and centrifuge, the system is phase-separated, take out the upper phase, evaporate and concentrate under reduced pressure to a density of 1.15-1.25g / mL, Obtain a preliminary purified tea sap...

Embodiment 3

[0023] After mixing a certain amount of choline chloride and ethylene glycol according to the molar ratio of 1:2, stir and heat at 80°C and 400rpm / min for 1h to form a uniform and transparent eutectic reagent; After drying in a vacuum drying oven at ℃, it is crushed by a traditional Chinese medicine pulverizer and passed through a 60-mesh sieve to further pulverize into cell-level ultrafine powder. Take 5.0kg tea seed cell-level ultrafine powder and 35% ethanol-0.35 dipotassium hydrogen phosphate salt solution to double After mixing the water phase system at a mass volume ratio of 1:15, centrifuge at 500W ultrasonic power, 200W microwave power and 35°C for 25 minutes to obtain the supernatant, and then extract the residue with ethanol-salt two-phase aqueous phase for 3 Combine the supernatant after the second time, add 30% choline chloride-ethylene glycol deep eutectic reagent into the supernatant, vortex for 20s and centrifuge, separate the phases of the system, take out the u...

Abstract

The invention discloses a preparation method of natural high-purity tea saponin with a function of efficiently decontaminating, and relates to the technical field of preparation of daily chemical products. The preparation method comprises the steps of firstly, extracting tea saponin from tea seed meal by adopting a microwave-ultrasonic assisted extraction combined two-aqueous-phase extraction technology; then, adopting a low-eutectic reagent-salt two-aqueous-phase extraction technology to remove the strong polar impurities in tea saponin so as to improve the purity of the saponin; finally, further purifying the tea saponin by using a supercritical CO2 extraction technology so as to obtain the high-purity natural tea saponin. The method provided by the invention is environmentally-friendlyand simple to operate; the obtained tea saponin is high in concentration and free from an organic solvent, and can be directly applied to the daily chemical products such as facial cleanser , shower gel, shampoo, soap and make-up remover.

Description

technical field [0001] The invention relates to the technical field of preparation of daily chemicals, in particular to a preparation method of highly efficient decontamination natural high-purity tea saponin. Background technique [0002] With the development of the market, the fierce competition and the continuous improvement of the needs of consumer groups, it is the general trend to develop daily chemical products with outstanding performance and amazing functions. At present, the decontamination effect of daily cleaning products mainly includes two categories: one is zwitterionic, non-ionic and cationic surfactants; the other is naturally extracted organic compounds, which mainly come from alcohol-soluble surfactants. Substances and aqueous extracts of Chinese herbal medicines. Due to the potential safety hazard of skin irritation in synthetic active agents, consumers are more and more inclined to choose natural decontamination products. [0003] Tea saponin is a prod...
