Example Embodiment
[0024] The preparation method of the rye columbine extract is as follows: crush the cleaned rye columbine, add 2-5 times of 50-70% ethanol solution, ultrasonically extract for 1-2 hours to obtain a mixture, and then add enzyme preparation to the mixture (According to the mass ratio, pectinase: cellulase: protease = 1:1:1 mixture) 0.1-2%, pH 7.0, temperature 50°C, enzymolysis for 2-5h, heat up to 90°C to kill the enzyme. The resulting mixture was centrifuged, the supernatant was concentrated, and freeze-dried to obtain the rye coax extract. Pectinase, cellulase and protease require enzyme activity ≥ 10,000 U / g.
[0025] Wherein the preparation method of the green tea extract is as follows: clean, dry and pulverize the green tea leaves, add 60-80% ethanol solution, ultrasonically extract for 1-2 hours at a temperature of 55-70°C, filter after cooling slightly, and carry out secondary extraction of the residue Extraction, the two extracts are mixed, concentrated by rotary evapor...
Example Embodiment
[0026] Example 1: Anti-wrinkle efficacy experiment of polyglutamic acid with different molecular weights
[0027] Table 1 Sodium Polyglutamate Molecular Weight and Content
[0028]
[0029] Dissolve the sodium polyglutamate with different molecular weights in the above table 1 in sterile water at 60°C respectively, stir and dissolve, then add phenoxyethanol and propylene glycol into the dissolved sodium polyglutamate solution after miscibility, Stand-by, the concentrations of phenoxyethanol and propylene glycol in the solution are both 0.5%. Select 80 volunteers (40 males and females, aged between 30 and 50 years old), with dry skin and obvious wrinkles, and randomly divide them into 4 groups, apply the sodium polyglutamate solution of different molecular weights in the above table 1 evenly on the left face sooner or later , Apply sterile water to the right face. The evaluation indicators are as follows, anti-wrinkle degree, expressed in the coefficient range of 0-10: 10 ...
