Embodiment 1
[0028] Put 5 grams of persimmon leaf polyphenols, 10 grams of collagen, 5 grams of papilloma flavonoids and 80 grams of deionized water into a mixer, stir and mix evenly, and then the whitening and anti-aging composition 1 can be obtained.
Embodiment 2
[0030] Put 7.3 grams of vitamin E and its derivatives, 14.8 grams of amino acids, 9.7 grams of nano-zinc oxide and 68.2 grams of deionized water in a mixer, stir and mix evenly, and the whitening and anti-aging composition 2 can be obtained.
Embodiment 3
[0032] Put 10 grams of platycodon phytosterols, 19 grams of betaine, 15 grams of silibinin and 66 grams of deionized water in a mixer, stir and mix evenly, and the whitening and anti-aging composition 3 can be obtained.
[0033] Verification of free radical scavenging efficacy
[0034] The preparation concentration is 1×10 -2 mol / L DPPH·dehydrated ethanol solution. The whitening and anti-aging compositions prepared in Examples 1-3 were prepared with 80% ethanol to prepare test sample solutions with concentrations of 0.01, 0.10, 0.15, 0.20, and 0.25, respectively. Take 5mL sample solution and DPPH solution respectively, mix them evenly, place them in the dark for 30min, adjust to zero with 80% ethanol, and measure the absorbance Ai at 517BITI; in the same way, take 5mL80% ethanol solvent and sample solution and mix with each other evenly, avoiding Measure the absorbance Aj after standing in the light for 30 min; add 5 mL of 80% ethanol solvent and 5 mL DPPH·solution to mix, k...
