Described Stichopus japonicus peptide extract prepares by the following method: after bright Stichopus japonicus is cleaned chopping, carry out enzymolysis with pepsin and two kinds of enzymes of trypsin: at first use the pepsin enzymolysis, pH is 2.0~2.5,35~60 ℃ of hydrolysis 2~8h, use the Trypsin enzymolysis then, pH is 8.0~8.5,35~60 ℃ of hydrolysis 2~8h, precipitation with alcohol (the ethanol volume ratio is 40~80%) is got supernatant, namely gets the Stichopus japonicus peptide extract after lyophilization or the spray drying.
The preparation method that described cosmetics add is: earthworm active protein extract and Stichopus japonicus peptide extract are proportionally mixed, and mixing namely gets cosmetics additive.The preparation method of earthworm active protein extract and Stichopus japonicus peptide extract such as above-mentioned.
Described cosmetics additive have the skin of making obviously delicate, elasticity obviously increases, effects such as wrinkle obviously shoals, moisture content of skin increase, can be used as the elite of preserving moisture, be directly used in skin, also can add in surfactant, elite, emulsion or the facial cream, make wrinkle removal and repair cosmetics, during practical application, cosmetics additive accounts for wrinkle removal and repairs 0.5~10% of cosmetics gross weight.
Cosmetics additive of the present invention can be used as elite and is directly used in skin, reaches the effect of crease-resistant reparation, also can add in surfactant, elite, emulsion or the facial cream, reaches the effect of crease-resistant reparation.Cosmetics additive of the present invention has active height, good biocompatibility, safe advantage such as have no side effect.
The specific embodiment
The present invention is further illustrated below in conjunction with embodiment.
Embodiment 1: the extraction of earthworm active protein extract
The fresh and alive Lumbricus 500g that cleans up is mixed with 1: 2 ratio of mass ratio with the phosphate buffer of pH7.2, and with organizing the inscribe refiner to pulverize homogenate, the Lumbricus homogenate is left standstill 6h, make the abundant stripping of albumen.Homogenate with 7000rpm high speed centrifugation 15min, is discarded precipitation, and supernatant adds ammonium sulfate and saltouts to reach 60% saturation, and the protein component precipitation is separated out.Adding back continuation stirring 10min fully dissolves ammonium sulfate.Solution with 4000rpm high speed centrifugation 15min, is discarded precipitation.Supernatant adopts the bag filter dialysis desalination of 3000 molecular weight, and lyophilization namely gets earthworm active protein extract 3g.
Embodiment 2: the extraction of Stichopus japonicus peptide extract
After bright Stichopus japonicus 500g cleans chopping, carry out enzymolysis with pepsin and two kinds of enzymes of trypsin: be 2.0-2.5 with pepsin enzymolysis pH at first, 50 ℃ of hydrolysis 5h, be 8.0-8.5 with Trypsin enzymolysis pH then, 50 ℃ of hydrolysis 5h, precipitation with alcohol (the ethanol volume ratio is 60%) is got supernatant, and lyophilization namely gets Stichopus japonicus peptide extract 50g.Pepsin and tryptic addition get final product according to the routine interpolation.
Embodiment 3: the preparation wrinkle removal is repaired astringent
Prescription is:
Add MEIGUI CHUNLU to 100ml.
The compound method of these cosmetics is as follows: the MEIGUI CHUNLU that adds 80ml behind earthworm active protein extract (embodiment 1 preparation), Stichopus japonicus peptide extract (embodiment 2 preparations), trehalose, the hyaluronic acid powder mixing is stirred, leaving standstill 12-24h dissolves fully to above-mentioned composition, add glycerol and germall Bp, add MEIGUI CHUNLU to 100ml.
