preparation example Construction

[0031] The application provides a preparation method of kapok extract, the preparation method of kapok extract comprises: using extractant to extract kapok, and collecting the liquid phase;

[0032] Wherein, the extractant includes the following components in parts by volume: 17-28 parts of betaine, 50-85 parts of glycerin and 0.4-9 parts of propylene glycol.

[0033] Specifically, the volume ratio of betaine, glycerol and propylene glycol is (17-28):(50-85):(0.4-9).

[0034] For example, the volume parts of betaine (chemical name N,N,N-trimethylglycine) can be 17 parts, 18 parts, 21 parts, 22 parts, 23 parts, 24 parts, 26 parts, 27 parts, 28 parts etc.

[0035] For example, the volume parts of glycerin can be 50 parts, 51 parts, 53 parts, 55 parts, 57 parts, 59 parts, 60 parts, 66 parts, 67 parts, 68 parts, 70 parts, 72 parts, 74 parts, 75 parts, 80, 81, 83, 84, 85 and so on.

[0036] For example, the volume parts of propylene glycol can be 0.4 parts, 0.5 parts, 1.2 parts,...

Embodiment 1

[0072] This embodiment provides a kind of kapok extract, which is mainly obtained through the following steps:

[0073] 1) The commercially available kapok is dried, pulverized, and passed through a 30-mesh sieve to obtain a powder. Take DES-TG and add water to configure 40% DES-TG aqueous solution to prepare extractant.

[0074] 2) Take 10g of kapok powder, add kapok according to the ratio of extractant to kapok powder of 1g:40ml, and perform high-voltage pulse extraction with a voltage of 600V and a pulse number of 80 times. Suction filtration is performed after the extraction is completed to obtain a kapok extract, which contains an extractant and an extract.

[0075] 3) The aluminum nitrate colorimetric method is used to detect the content of flavonoids in the kapok extract. Specifically, the detection method is as follows:

[0076] Take 2.4mL of kapok extract diluted to a certain multiple in a stoppered test tube, then add 5wt% NaNO 2 Solution 0.4mL, react after mixing...

Embodiment 2- Embodiment 5

[0078] Embodiment 2-Example 5 respectively provide a kind of kapok extract, please refer to Example 1, the difference between Example 2-Example 5 and Example 1 is that the extractant is different. In embodiment 2-embodiment 5, extractant adopts the following steps to make:

[0079] Mix betaine and ethanol, stir at room temperature until the solution is uniform, slowly add glycerin and propylene glycol, and then place the mixed solution in a nitrogen atmosphere at room temperature and magnetically stir for 8 hours. During the stirring process, the whole process is protected from light. Store at 0°C for 10h. Ethanol and water were removed by vacuum rotary evaporation to obtain the extractant, and the volume ratios of glycerol, propylene glycol and betaine are shown in Table 1.

[0080] All the other preparation methods and preparation techniques are the same as in Example 1.

[0081] Calculate the total flavonoid extraction rate according to the following formula:

[0082] To...

Abstract

The invention relates to the field of skin care product raw materials, in particular to a kapok extract and a preparation method and application thereof. The preparation method of the kapok extract comprises the following steps: extracting kapok by adopting an extracting agent, and collecting a liquid phase; wherein the extracting agent is prepared from the following components in parts by volume: 17 to 28 parts of betaine, 50 to 85 parts of glycerol and 0.4 to 9 parts of propylene glycol. When the kapok is extracted by adopting the extracting agent, the extracting agent can not be removed after the extraction is completed, and the preparation method can obtain more flavonoids, so that the extraction process is saved while the extraction rate of the kapok flavonoids is improved, and the antioxidant level of the kapok extract is improved.

Description

technical field [0001] This application relates to the field of raw materials for skin care products, in particular, it relates to a kapok extract and its preparation method and application. Background technique [0002] Kapok mainly contains chemical components such as flavonoids, organic acids, steroids, triterpenes, and coumarins. [0003] Kapok flavonoids can be used as raw materials for skin care products, but the antioxidant capacity of kapok flavonoids extracted by the prior art is limited. Contents of the invention [0004] The purpose of the embodiment of the present application is to provide a kapok extract and its preparation method and application, which aims to improve the extraction efficiency of kapok flavonoids. [0005] The application provides a preparation method of kapok extract, comprising: [0006] extracting kapok with an extractant, and collecting the liquid phase; [0007] Wherein, the extractant includes the following components in parts by vol...
