Embodiment 1

[0031] A deep eutectic solvent combined with mechanochemical extraction was used to extract alkaloids, flavonoids, and tea polyphenols from tea leaves.

[0032] (1) Target extract

[0033] Caffeine (CAF), Theobromine (TBM), Kaempferol (KAE), (-)-Epicatechin (EC), (-)-Epicatechin Gallate (ECg), (-)- Epigallocatechin (EGC) and (-)-epigallocatechinate (EGCg).

[0034] (2) Preparation of deep eutectic solvent

[0035] Heat and stir proline and glycerin with a molar ratio of 1:1-1:4 at 60-120°C for 30 minutes-2 hours to a homogeneous phase, and then dilute the deep eutectic solvent with water to 10-90% (mass percentage ).

[0036] Of course, the deep eutectic solvent of this embodiment can also be obtained by mixing other hydrogen bond acceptors and other hydrogen bond donors after heating, and other hydrogen bond acceptors can be quaternary ammonium salts, zwitterions, amino acids, sugars, carboxylic acids at least one of;

[0037] Other hydrogen bond donors may be at least o...

Embodiment 2

[0051] Deep eutectic solvent extracts are used to process liquid soaps1.

[0052] (1) Making soap paste

[0053] Mix 85 g of coconut oil, 10 g of palm kernel oil, 5 g of cocoa butter, 18 g of potassium hydroxide, and 55 g of water and raise the temperature to 70-90 degrees until completely dissolved, and then continue heating for 2-3 hours until it becomes transparent.

[0054] (2) Soap paste dilution

[0055] 30g of soap paste, 65g of water, and 5g of deep eutectic solvent extract are mixed and poured into a pot until completely dissolved, and bottled for use.

Embodiment 3

[0057] The deep eutectic solvent extract was used to process liquid soap 2.

[0058] (1) Making soap paste

[0059] Mix 75 g of coconut oil, 10 g of olive oil, 15 g of castor oil, 24 g of potassium hydroxide, and 71 g of water and heat up to 70-90 degrees until completely dissolved, then continue heating for 2-3 hours until it becomes transparent.

[0060] (2) Soap paste dilution

[0061] 57g of soap paste, 38g of water, and 5g of deep eutectic solvent extract are mixed and poured into a pot until completely dissolved, and bottled for use.

[0062] Embodiment Three

[0063] Deep eutectic solvent extracts are used to process moisturizing lotions.

[0064] 1% paraffin, 2% beeswax, 2% lanolin, 20% liquid paraffin, 10% isotriaxane, 4% sorbitan sesquioleate, 1% sorbitan monooleate, Melt solvent (glycerin is replaced by propylene glycol) extract 7%, refined water 53%, mix and dissolve, keep 70 degrees, pour the water phase into the oil phase, emulsify with a homogenizer, and coo...

Abstract

The invention discloses an extraction method and application of an active substance extracting solution. The method comprises the following steps: preparing an extracting solution, wherein the extracting solution at least comprises a eutectic solvent; adding an animal, plant or microorganism sample into the extracting solution; carrying out mechanical chemical extraction; carrying out centrifuging; and taking out the supernatant which is the active substance extracting solution. The method disclosed by the invention can be used for carrying out efficient and pollution-free extraction on activecomponents in animal, plant or microorganism samples, high temperature is not needed in the extraction process, and consumption of toxic organic solvents is not needed, so that environmental pollution is reduced. In a process of preparing daily chemical products by the extracting solution, the solvent is not required to be removed, and the extracting solution can be directly used. The method hasthe characteristics of simple operation, short time consumption, low cost and high extraction efficiency.

Description

technical field [0001] The invention relates to an extraction method and application of an active substance extract. Background technique [0002] In recent years, biologically active natural products have attracted more and more attention from the world in terms of pharmacology and biology. These products have the functions of treating diseases, improving physical fitness and skin care and beauty. Active ingredients in animals, plants and microorganisms are attracting more and more attention due to their safety, reliability and remarkable activity. The biologically active substances contained in them have physiological activities such as anti-oxidation, elimination of free radicals, and anti-inflammation. Therefore, its active ingredients are increasingly used in the field of daily chemicals. However, in many cases, these active ingredients need to be extracted using organic solvents, and most organic solvents are usually toxic and volatile, causing environmental pollution...
