preparation example Construction

[0024] Disclosed in a preferred embodiment of the present invention is a method for preparing the extract of Jasmine Japonica, comprising the following steps:

[0025] S1: dry a part by weight of golden button flowers, add 6a to 10a parts by weight of organic solvent for soaking, and then extract to obtain an extract. After the extract is filtered by suction, it is concentrated under reduced pressure to obtain a part by weight of golden button flower suspension;

[0026] S2: Add 4a to 6a parts by weight of deionized water to a part by weight of the Japonica japonica suspension, centrifuge and pass through filter membranes of at least two pore sizes in sequence to obtain a retentate, concentrate the retentate under reduced pressure, and freeze Dried to obtain the golden button flower powder of b weight part;

[0027] S3: adding b parts by weight of the jelly button flower powder into 4b-6b parts by weight of the dissolving solvent, heating and dissolving to obtain the jellis z...

[0037] Embodiment 1: Preparation of golden button flower extract A

[0038]Weigh C buttons by weight, dry, add 8 c parts by weight of 50% by mass ethanol aqueous solution and soak for 40 minutes, then perform dual-frequency ultrasonic extraction, the extraction conditions are 25KHz, 49KHz, the temperature is 20°C, and the extraction time is 20min; After extracting solution is suction-filtered, concentrating under reduced pressure obtains the jellyfish suspension of c weight parts (with raw material weight ratio 1:1); Obtain the jellyfish suspension of equal quality with jellyfish raw material in this step, on the one hand It has ensured that the solvent is removed (that is, if the quality of the jaggery suspension is greater than that of the jaggery raw material, there is still solvent in the jaggery suspension that has not been removed), and on the other hand, it is also prevented from passing through the filter membrane in subsequent steps. Cause clogging membrane pore size ...

Abstract

The invention discloses a preparation method of a spilanthes extract. The preparation method comprises the following steps: drying a parts by weight of spilanthes, soaking the spilanthes in 6a to 10a parts by weight of an organic solvent, then extracting to obtain extract liquor, carrying out suction filtration on the extract liquor, and then concentrating by reduced pressure to obtain a parts by weight of spilanthes suspension; adding 4a to 6a parts by weight of deionized water in the a parts by weight of the spilanthes suspension, after centrifuging, successively filtering the mixture through filter membranes with at least two apertures to obtain trapped fluid, condensing the trapped fluid by reduced pressure and carrying out freeze drying on the trapped fluid to obtain b parts by weight of spilanthes powder; adding the b parts by weight of the spilanthes powder in 4b to 6b parts by weight of a dissolving solvent, and carrying out heating and dissolving to obtain the spilanthes extract. The invention further discloses a spilanthes extract and application of the spilanthes extract in a skin care product. The preparation method of the spilanthes extract is safe, reliable, simple and effective; the spilanthes extract is used in the skin care product, and the effect of reducing skin melanin, namely the effect of whitening skin, can be achieved.

Description

technical field [0001] The invention relates to the field of natural product extraction technology and skin care products, and in particular to the extract of japonica japonicus and its preparation method, and its application in skin care products. Background technique [0002] The color of human skin depends on the content and distribution of melanin. When a large amount of melanin is deposited unevenly in the human body, freckles and chloasma will form. Tyrosinase widely exists in the human body and is the key enzyme for producing melanin. The formation process of melanin is as follows: tyrosine in human skin melanocytes is oxidized under the catalysis of tyrosinase to form dopa and dopaquinone, which are further oxidized after rearrangement to form dopachrome, 5,6-di Oxindole, indolequinone, and finally melanin. At present, the main mechanism of commonly used whitening agent cosmetics is to inhibit the activity of tyrosinase or block the oxidation of tyrosine to produce...
