Embodiment 1～11

[0056] Embodiment 1~11, the preparation of camellia extract

[0057] The concrete preparation method of the camellia extract of embodiment 1~11 is as follows:

[0058] 1) Fresh camellia or fresh camellia flower buds, remove impurities and chop into small pieces of 0.5-3cm, as raw materials for later use;

[0059] 2) Put a certain amount of raw materials into an ultrasonic kettle, add a solvent with a mass ratio of 1:3 to 30 to the raw materials, stir evenly and add 0.25 to 2.5% of the solvent mass of inorganic acid and / or organic acid to control the pH When the value is 1.3-3.0, soak in the mixture for 10-30 minutes;

[0060] 3) Ultrasonic treatment is performed on the mixed liquid soaked in step 2) for 30-60 minutes, the ultrasonic frequency is 20-25KHz, the ultrasonic power is 1.0-2.0KW, the ultrasonic temperature is 15-50°C, and the camellia extract is obtained by filtration.

[0061] 4) Sterilize and test the efficacy of the camellia extract.

[0062] The camellia ext...

Embodiment 12

[0070] Adopt high performance liquid chromatography to detect respectively the active ingredient in the extract of embodiment 1~11 and comparative example 1~2, the HPLC collection of illustrative plates of embodiment 3, comparative example 1 and comparative example 2 are respectively as follows figure 2 , image 3 with Figure 4 shown by Figure 2 to Figure 4 It can be seen that the camellia extract of the present invention contains a variety of active components, and the types and contents of the active components are significantly higher than those of the camellia extracts of Comparative Example 1 and Comparative Example 2.

[0071] The contents of antioxidant active components in the extracts of Examples 1-11 and Comparative Examples 1-2 were analyzed, and the results are shown in Table 2 and Table 3.

Embodiment 13

[0077] Embodiment 13: scavenging DPPH free radical test

[0078] Respectively 0.04g, 0.08g, 0.16g, 0.312g, 0.625g, 1.25g, 2.5g, 5.0g and 10.0g of the camellia extract prepared in Example 1 were diluted with water to 100g to obtain extracts containing 0.04%, 0.08 %, 0.16%, 0.312%, 0.625%, 1.25%, 2.5%, 5.0% and 10.0% of the detection solution, the DPPH free radical scavenging rates of different concentrations of the detection solution are respectively detected as shown in Table 4.

[0079] The DPPH free radical scavenging rate of table 4 different concentrations detection solution

[0080]

[0081] As can be seen from the data in Table 4, with the increase of the extract content in the test solution, the DPPH free radical scavenging rate of the test solution continues to increase, and when the concentration is greater than 2.5%, the DPPH free radical scavenging rate tends to be stable, indicating that Camellia japonica When the concentration of the extract is 2.5%, it can ...

Abstract

The invention provides a preparation method of camellia extraction liquid. The method comprises the following steps of 1) removing impurities of fresh camellia and / or fresh camellia buds; cutting up the fresh camellia and / or fresh camellia buds into small sections for use as raw materials; 2) taking a certain number of raw materials; putting the raw materials into an ultrasonic kettle; adding a solvent with the mass ratio being 1:(3-30); uniformly stirring the mixture; adding a certain amount of inorganic acid and / or organic acid; regulating the pH value to 1.3 to 3.0; soaking the materials for 10 to 30 min; 3) then performing ultrasonic treatment for 30 to 60min; controlling the ultrasonic frequency to be 20 to 25KHz, the ultrasonic power to be 1.0 to 2.0KW and the ultrasonic temperature to be 15 to 50 DEG C; then performing filtration, sterilization and detection to obtain camellia extraction liquid. The camellia extraction liquid maintains the color, luster, flavor and effective active ingredients of the camellia to the maximum degree; the anti-oxidation functional ingredients are overall; the contents are high; the safety and the stability are high; cosmetics prepared by using camellia extraction liquid as active ingredients have the excellent whitening, spot-reducing and anti-aging efficacies.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a camellia extract and its preparation method and application. Background technique [0002] Camellia, also known as Camellia, is a plant of the genus Camellia in the family Theaceae. It originated in China and has a long history of cultivation. Up to now, Japan, South Korea, Australia, the United States and other countries have developed rapidly in the breeding, planting and production of Camellia, and have entered the field of industrial production. stage. Camellia has the functions of promoting blood circulation to stop bleeding, astringent and antidiarrheal, detoxification and astringent sores. The rich flavonoids, saponins, and polyphenols contained in camellia have excellent anti-oxidation and anti-free radical effects. Cosmetics prepared with them have the effects of anti-free radicals, anti-aging, lightening spots, moisturizing, and sun protection. [0003...
