Anti-inflammatory thiab antioxidant ob-pronged mus kom ze - natural skincare ingredient, phloretin!

1.-Phloretin yog dab tsi-

Phloretin(Lus Askiv lub npe: Phloretin), tseem hu ua trihydroxyphenolacetone, belongs rau dihydrochalcones ntawm flavonoids. Nws yog concentrated nyob rau hauv lub rhizomes los yog keeb kwm ntawm txiv apples, strawberries, pears thiab lwm yam txiv hmab txiv ntoo thiab ntau yam zaub. Nws muaj npe tom qab daim tawv nqaij. Nws yog soluble hauv alkali tov, yooj yim soluble hauv methanol, ethanol thiab acetone, thiab yuav luag insoluble hauv dej.

Phloretin tuaj yeem nqus tau ncaj qha los ntawm tib neeg lub cev, tab sis hauv cov nroj tsuag, muaj qhov tshwm sim me me ntawm phloretin. Phloretin feem ntau muaj nyob rau hauv daim ntawv ntawm nws glycoside derivative, phlorizin. Lub phloretin absorbed los ntawm tib neeg lub cev yog nyob rau hauv lub plab mucosa. Tsuas yog tom qab cov pab pawg glycoside raug tshem tawm los tsim phloretin tuaj yeem nkag mus rau hauv cov hlab ntsha thiab siv nws cov nyhuv.

Lub npe tshuaj: 2,4,6-trihydroxy-3-(4-hydroxyphenyl)propiophenone

Cov mis mos molecular: C15H14O5

Molecular Luj: 274.27

2.-Lub luag haujlwm tseem ceeb ntawm phloretin-

tiv thaiv oxidation

Flavonoids muaj kev tiv thaiv cov rog oxidation, uas tau lees paub thaum ntxov li xyoo 1960: cov qauv polyhydroxyl ntawm ntau cov flavonoids tuaj yeem muaj cov khoom tseem ceeb antioxidant los ntawm chelating nrog hlau ions.

Phloretin yog ib qho zoo heev ntuj antioxidant. Cov qauv 2,6-dihydroxyacetophenone muaj cov nyhuv antioxidant zoo heev. Nws muaj cov txiaj ntsig pom tseeb ntawm kev tshem tawm peroxynitrite thiab muaj cov tshuaj antioxidant siab hauv cov roj. Ntawm 10 thiab 30PPm, nws tuaj yeem tshem tawm cov dawb radicals hauv daim tawv nqaij. Phlorizin cov tshuaj tiv thaiv antioxidant yog txo qis vim tias nws pawg hydroxyl ntawm txoj haujlwm 6 yog hloov los ntawm ib pawg glucosidyl.
Inhibit tyrosinase

Tyrosinase yog tooj liab-muaj metalloenzyme thiab yog ib qho enzyme tseem ceeb hauv kev tsim melanin. Cov kev ua tyrosinase tuaj yeem siv los ntsuas seb cov khoom puas muaj cov nyhuv whitening. Phloretin yog ib qho rov qab sib xyaw inhibitor ntawm tyrosinase. Nws tuaj yeem tiv thaiv tyrosinase los ntawm kev khi rau nws cov substrate los ntawm kev hloov cov qauv thib ob ntawm tyrosinase, yog li txo nws txoj haujlwm catalytic.

Antibacterial kev ua haujlwm

Phloretin yog ib qho flavonoid compound nrog cov tshuaj tua kab mob. Nws muaj kev cuam tshuam rau ntau yam kab mob Gram-positive, kab mob Gram-negative thiab fungi.
Cov kev sim tshuaj ntsuam xyuas pom tau hais tias tom qab cov neeg siv phloretin rau 4 lub lis piam, whiteheads, blackheads, papules, thiab sebum secretion tau txo qis, qhia tias phloretin muaj peev xwm txo tau pob txuv.

3. Cov khoom xyaw pom zoo
essence
2% phloretin(antioxidant, whitening) + 10% [l-ascorbic acid] (antioxidant, collagen txhawb thiab whitening) + 0.5%ferulic acid(antioxidant thiab synergistic nyhuv), muaj peev xwm tiv taus ultraviolet rays nyob rau hauv ib puag ncig, infrared hluav taws xob thiab ozone puas rau ntawm daim tawv nqaij, brighten cov tawv nqaij laus, thiab yog haum rau oily daim tawv nqaij nrog dull tawv nqaij.
