Product Introduction

Isu tinopa 3-O-Ethyl-L-ascorbic acid

Tinofara kupa 3-O-Ethyl-L-ascorbic asidhi, fomu yakakosha uye yakagadzikana yevhitamini C. Ichi chikamu chitsva chakanyatsogadzirirwa kusimbisa collagen conflation uye buck up tone yeganda, zvichiita kuti ive yakanyanya kutsvakwa-kuwedzera kune zvakasiyana-siyana zvekushongedza zvirevo. Nekugadzikana kwayo kunoshamisa, 3-O-Ethyl ascorbic Acid inopa yakavimbika uye inowirirana mhedzisiro, icing kuti zvigadzirwa zvako zvinounza zvakashongedzwa zvinogoneka nyaya kune vaenzi vako. Saka kana iwe uchitsvaga inoshanda uye inovimbika vhitamini C yekukura kwekuwedzera zvigadzirwa zvako, usatarise kunze kwedu. vitamini C ethyl ether.

 

Chii chinonzi 3-O-Ethyl-L-ascorbic acid?

3-O-Ethyl-L-ascorbic acid, inozivikanwawo sevhitamini C ethyl ether. Nekuda kweayo mana hydroxyl mapoka muchimiro, vhitamini C haigone kubatwa zvakananga neganda uye inokwenenzverwa oxidized, zvichitungamira kune abrasion. Kushandiswa kwaro se decolorizing agent muzvizorori kunogumira. Iyo VC ethyl ether inowanwa ne3- hydroxyalkylation ndeye isiri discoloring yevhitamini C inokura iyo isingakanganise kushanda kwayo kwechisikigo, saka ichizadza mukaha muzvigadzirwa zvakafanana mukukumbira. Tsvagiridzo yakaratidza kuti inoputswa zvakapusa nema enzymes mushure mekupinda muganda, ichiita vhitaminiC.

Inobatsira zvechokwadi kubuda kwevhitamini C, iyo isiri chete kugadzikana kwemakemikari uye haishandure ruvara sevhitamini C inobuda, asiwo hydrophilic uye amphiphilic substance. Izvi zvinowedzera zvakanyanya kubatana kwayo mumunda weinjiniya yemakemikari, kunyanya mukushanda kwemakemikari diurnal. 3- O- ethylascorbic acid ether inopinda zvakanaka mudermis kuburikidza ne stratum corneum, uye mushure mekupinda mumuviri, inoparara zvakanaka nema enzymes echisikigo kupuruzira zvinhu zvakasikwa zvevhitamini C.

Chii chinonzi Main basa re3-O-Ethyl-L-ascorbic acid?

l. Mushure mekupinda mudermis, VC ethyl ether inotora chikamu zvakananga mukugadzirwa kwe collagen kugadzirisa masero eganda, kuwedzera collagen uye kuita kuti ganda rive rakazara uye elastic, zvichiita kuti ganda rive rakapfava uye rakatsetseka.

2. Kudzivisa basa re tyrosinase, kudzivisa kuumbwa kwe melanin, kuderedza melanin kusvika kusina ruvara, uye kunyatsochenesa ganda.

3. Pane antioxidant effect muzvizoro, kuve nechokwadi chekushandiswa kweVC. Kuenzaniswa neVC, VC ethyl ether yakanyatsogadzikana uye haichinji ruvara. Chokwadi zadzisa mhedzisiro yekuchena uye kubvisa freckle.

4. Iine oleophilic uye hydrophilic structure, iyo iri nyore kuti ganda ritore uye rinogona kusvika kune dermis zvakananga.

5. Yakasimba antibacterial uye anti-inflammatory effects, anti kuzvimba kunokonzerwa nechiedza chezuva.

7. Kugadzikana kwakanaka, kunopesana nechiedza, kupisa, asidi, alkali, munyu, uye air oxidation

8. Iyo inhibitory mhedzisiro yevhitamini C uye zvinobva kune tyrosinase

 

Chii Chinangwa che3-O-Ethyl-L-ascorbic acid?

Vitamin C ethyl ether (VC ethyl ether) is oleophilic uye hydrophilic amphoteric vhitamini C kubva, iyo isingango chengetedza redox mhedzisiro yevhitamini C asi zvakare yakagadzikana kwazvo. Iyo isiri discoloring vhitamini C kubva, uye zvakare iri oleophilic uye hydrophilic amphoteric chinhu mubhuku remakemikari. Izvi hazvingoite kuti zvive nyore kushandisa mumafomula, asi zvakare zvinoita kuti zvive nyore kupinda mu stratum corneum uye kupinda mudermis. Mushure mekupinda muganda, inosvibiswa nyore nyore ne biological enzymes kuti iite basa revhitamini C, nekudaro inovandudza bioavailability yayo.

 

Chii chinonzi Mechanism yekuita ye3-O-Ethyl-L-ascorbic acid?

VC ethyl ether inosvika kune basal layer ye melanocytes kuburikidza ne stratum corneum, inhibits tyrosinase chiitiko, inhibits melanin kuumbwa, inoderedza melanin kuti isina ruvara, uye inonyatso chena ganda. Uye VC ethyl ether inogona kutora chikamu zvakananga mukugadzirwa kwe collagen uye kugadzirisa ganda sero chiitiko mushure mekupinda mudermis, kuwedzera collagen uye kuita kuti ganda rizare uye elastic, zvichiita kuti ganda rive rakapfava uye rakatsetseka. 3-O-ethyl-L-ascorbic asidhi inogona kunge yakagadzikana inobatsira yehydroxyacetophenone mhinduro.

 

Chii chinonzi 3-O-Ethyl-L-ascorbic acid?

3-O-ethylascorbic acid ether chinhu chinonyungudika mumafuta nemvura, zvichibvumira vagadziri kuti vawedzere zvakasununguka kuchikamu chemafuta kana chemvura, pamwe chete nekupisa kwepamusoro kana kuderera, zvichiita kuti zvive nyore kushandisa. Zvinotonyanya kukosha, kunyungudika kuviri uku kunoita kuti zvive nyore kuti ipinde mu stratum corneum uye kupinda mudermis kuti iite zvipenyu zvayo, izvo zvisina mamwe mavhitamini C anobuda. Inogona kuvhara kuumbwa kwe melanin nekudzivisa basa re tyrosinase; Iine kuchena uye freckle kubvisa mhedzisiro (kana yawedzerwa pa2%); Kuzvimba kunokonzerwa ne-anti-Japanese light kune yakasimba antibacterial uye anti-inflammatory effects; Panguva imwe cheteyo kuvandudza kusimba uye kusasimba kweganda, kuripa nekupenya uye elasticity, kugadzirisa masero eganda, uye kukurudzira kugadzirwa kwe collagen.

1. Kuvharidzirwa kwebasa re tyrosinase neCu2 + kuita pairi, kuvhara melanin kuumbwa;

2. Kunyanya kuchena kunoshanda uye freckle kubvisa mhedzisiro (kana yawedzerwa pa2%);

3. Kuzvimba kunokonzerwa ne-anti-Japanese light, ine antibacterial yakasimba uye anti-inflammatory effects;

4. Kuvandudza kupenya uye kupera kweganda, kuchipa elasticity;

5. Gadzirisa masero eganda uye kukurudzira kugadzirwa kwe collagen.

 

Kugadzirira kwe3-O-Ethyl-L-ascorbic acid

1) Synthesis ye5,6-O-isopropylidene ascorbic acid: 70g ye ascorbic acid, 22g ye-p-toluenesulfonic acid, uye 700ml yeacetone yakawedzerwa kune 1.5-lita imwe yemutsipa flask. Maitiro akaitwa pakamuri tembiricha (25 ℃) kwemaawa masere, uye huwandu hukuru hwemakristasi hwakagadzirwa mune mhinduro mhinduro. Mushure mekusefa, keke resefa raigezwa neacetone uye vacuum yakaomeswa kuwana 8g ye80-O-isopropylidene-L ascorbic acid makristasi ane goho re5,6%. Mushure mekuwedzera neacetone uye ascorbic acid, kudzokorora danho iri rekuita kunogona kuburitsa 93-O-isopropylidene-L ascorbic acid.

2) Synthesis ye 3-O-alkyl-5,6-O-isopropylene ascorbic acid: DMSO inoshandiswa seyakagadziriswa, uye molar ratio ye bromoethane kune ascorbic acid ndeye 0.5 / 1. Weresa 30 magiramu e5,6-O-isopropylidene-L ascorbic acid, inyungudise mu120 milliliters eDMSO, wedzera 7.6 magiramu ebromoethane uye 11.6 magiramu e sodium bicarbonate, uye wozoita pa70 ℃ kwemaawa maviri. Mushure mekutonhodza kusvika kune tembiricha yekamuri (2 ℃), bvisa katatu ne25 milliliters e toluene. Mushure mekugeza nemvura, nyatsoisa uye crystallize iyo yakabudiswa kuti uwane 1000 gramu ye 16.2-O-ethyl-3-O-isopropylene ascorbic acid, ine chibereko che5,6% chakaverengwa nebromoethane. Muenzaniso 95-O-Ethyl-103-O-isopropyleneascorbic acid deprotection:

3) Synthesis ye3-O-ethylascorbic acid: Dissolve magiramu gumi e10-O-ethyl-3-O-isopropyleneascorbic acid mu5,6 milliliters emethanol, wobva wawedzera 100 milliliters (chikamu chechikamu che5%) chehydrochloric acid, kupisa kusvika 50 ℃, uye ita kwemaawa matatu. Mushure mekusagadzikana ne sodium bicarbonate uye kudhirowa ne ethyl acetate, 60 magiramu e 3-O-ethyl ascorbic asidhi akawanikwa, aine goho re98%.
