Mgbochi mkpali na antioxidant ụzọ ụzọ abụọ - ihe nlekọta anụ ahụ anụ ahụ, phloretin!

1.-Gịnị bụ phloretin

Phloretin(Aha bekee: Phloretin), makwaara dị ka trihydroxyphenolacetone, bụ nke dihydrochalcones n'etiti flavonoids.Ọ na-etinye uche na rhizomes ma ọ bụ mgbọrọgwụ nke apụl, strawberries, pears na mkpụrụ osisi ndị ọzọ na akwụkwọ nri dị iche iche.A na-akpọ ya aha akpụkpọ ahụ.Ọ bụ soluble na alkali ngwọta, mfe soluble na methanol, ethanol na acetone, na ọ fọrọ nke nta insoluble na mmiri.

Ahụ mmadụ nwere ike itinye phloretin ozugbo, mana n'ime osisi, phloretin dị ntakịrị na-apụta.Phloretin na-adịkarị n'ụdị nke glycoside sitere na ya, phlorizin.Phloretin nke ahụ mmadụ na-etinye n'ime ya dị na mucosa gastric.Naanị mgbe ewepụsịrị glycoside otu iji mepụta phloretin, ọ nwere ike ịbanye na sistemụ mgbasa ma nwee mmetụta ya.

Aha kemịkal: 2,4,6-trihydroxy-3- (4-hydroxyphenyl)propiophenone

Usoro ihe omimi: C15H14O5

2.-Main ọrụ nke phloretin-

mgbochi oxidation

Flavonoids nwere ọrụ oxidation na-egbochi abụba, bụ nke akwadoro na mmalite afọ 1960: ihe owuwu polyhydroxyl nke ọtụtụ flavonoids nwere ike inwe mmetụta antioxidant dị ukwuu site na iji ion ígwè chelating.

Phloretin bụ ezigbo antioxidant eke.Ọdịdị 2,6-dihydroxyacetophenone nwere mmetụta antioxidant dị mma.Ọ nwere mmetụta doro anya na mkpochapụ peroxynitrite ma nwee nnukwu mkpokọta antioxidant na mmanụ.N'etiti 10 na 30PPm, ọ nwere ike wepụ free radicals na akpụkpọ.Ọrụ antioxidant nke Phlorizin na-ebelata nke ukwuu n'ihi na otu glucosidyl nọchiri otu hydroxyl ya na ọnọdụ 6.
Na-egbochi tyrosinase

Tyrosinase bụ metalloenzyme nwere ọla kọpa ma bụrụ isi enzyme na-emepụta melanin.Enwere ike iji ọrụ tyrosinase nyochaa ma ngwaahịa ahụ nwere mmetụta na-acha ọcha.Phloretin bụ ihe na-egbochi tyrosinase na-agbanwe agbanwe.Ọ nwere ike igbochi tyrosinase ka ọ ghara ijikọ na mkpụrụ ya site n'ịgbanwe usoro nke abụọ nke tyrosinase, si otú ahụ belata ọrụ catalytic ya.

Antibacterial ọrụ

Phloretin bụ ngwakọta flavonoid nwere ọrụ antibacterial.Ọ nwere mmetụta inhibitory na ọtụtụ nje bacteria gram-positive, gram-negative bacteria na fungi.
Nsonaazụ nyocha ụlọ ọgwụ na-egosi na mgbe ihe ọmụmụ jiri phloretin mee ihe maka izu 4, a na-ebelata isi ọcha, blackheads, papules, na sebum secretion nke ukwuu, na-egosi na phloretin nwere ikike iwepụ ihe otutu.

isi
2% phloretin(antioxidant, ọcha) + 10%l-ascorbic acid] (antioxidant, nkwalite collagen na ịcha ọcha) + 0.5%ferulic acid(antioxidant na synergistic mmetụta), nwere ike iguzogide ụzarị ultraviolet na gburugburu ebe obibi, radieshon infrared na ozone mebiri akpụkpọ ahụ, na-eme ka ụda akpụkpọ ahụ dịkwuo mma, ọ dịkwa mma maka akpụkpọ mmanu mmanu na ụda akpụkpọ anụ.
