Njira yolimbana ndi kutupa komanso antioxidant ya mbali ziwiri - chinthu chosamalira khungu, phloretin!

1.-Kodi phloretin ndi chiyani?

Phloretin(Dzina la Chingerezi: Phloretin), yomwe imadziwikanso kuti trihydroxyphenolacetone, ndi ya dihydrochalcones pakati pa flavonoids. Iwo anaikira mu rhizomes kapena mizu ya maapulo, strawberries, mapeyala ndi zipatso zosiyanasiyana ndi masamba. Amatchulidwa ndi khungu. Imasungunuka mu njira ya alkali, imasungunuka mosavuta mu methanol, ethanol ndi acetone, komanso pafupifupi yosasungunuka m'madzi.

Phloretin imatha kuyamwa mwachindunji ndi thupi la munthu, koma muzomera, mumapezeka phloretin yochepa kwambiri mwachilengedwe. Phloretin nthawi zambiri imakhala mu mawonekedwe a glycoside yochokera ku phlorizin. Phloretin yotengedwa ndi thupi la munthu ili m'matumbo a m'mimba. Pokhapokha gulu la glycoside litachotsedwa kuti lipange phloretin lingathe kulowa mu kayendedwe ka kayendedwe kake ndikugwira ntchito yake.

Dzina la mankhwala: 2,4,6-trihydroxy-3-(4-hydroxyphenyl)propiophenone

Mapangidwe a maselo: C15H14O5

Kulemera kwa molekyulu: 274.27

2.-Ntchito zazikulu za phloretin-

anti-oxidation

Ma Flavonoids ali ndi anti-oxidation oxidation activate, yomwe yatsimikiziridwa kale m'ma 1960: mapangidwe a polyhydroxyl a flavonoids ambiri amatha kukhala ndi antioxidant katundu poyesa ndi ayoni achitsulo.

Phloretin ndi antioxidant wachilengedwe. Mapangidwe a 2,6-dihydroxyacetophenone ali ndi antioxidant effect. Lili ndi zotsatira zoonekeratu pa scavenging peroxynitrite ndipo ali mkulu antioxidant ndende mu mafuta. Pakati pa 10 ndi 30PPm, imatha kuchotsa ma radicals aulere pakhungu. Mphamvu ya antioxidant ya phlorizin imachepetsedwa kwambiri chifukwa gulu lake la hydroxyl lomwe lili pamalo 6 limasinthidwa ndi gulu la glucosidyl.
Kuletsa tyrosinase

Tyrosinase ndi metalloenzyme yokhala ndi mkuwa ndipo ndi puloteni yofunika kwambiri popanga melanin. Ntchito ya tyrosinase ingagwiritsidwe ntchito kuwunika ngati mankhwalawo ali ndi kuyera. Phloretin ndi reversible mix inhibitor ya tyrosinase. Ikhoza kulepheretsa tyrosinase kuti isamangirire ku gawo lapansi mwa kusintha mawonekedwe achiwiri a tyrosinase, potero kuchepetsa ntchito yake yothandizira.

Antibacterial ntchito

Phloretin ndi flavonoid pawiri ndi antibacterial ntchito. Zili ndi zotsatira zolepheretsa pamitundu yosiyanasiyana ya mabakiteriya a gram-positive, mabakiteriya a gram-negative ndi bowa.
Zotsatira za mayesero a zachipatala zimasonyeza kuti anthu atagwiritsa ntchito phloretin kwa masabata a 4, whiteheads, blackheads, papules, ndi sebum secretion adachepetsedwa kwambiri, kusonyeza kuti phloretin imatha kuthetsa ziphuphu.

3. Zosakaniza zovomerezeka
zenizeni
2% phloretin(antioxidant, whitening) + 10% [l-ascorbic asidi] (antioxidant, kukwezedwa kwa collagen ndi kuyera) + 0.5%asidi ferulic(antioxidant ndi synergistic effect), imatha kukana kuwala kwa ultraviolet m'chilengedwe, cheza cha infrared ndi kuwonongeka kwa ozoni pakhungu, kuwunikira khungu, komanso koyenera kwambiri pakhungu lamafuta ndi khungu losawoneka bwino.
