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. A na-ebelata ọrụ antioxidant nke Phlorizin 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.
