Gallic Acid thiab Tannic Acid

Gallic acid thiab tannic acid, raws li ob yam tseem ceeb ua haujlwm, tau txais kev saib xyuas ntau ntxiv hauv cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab kev lag luam. Txawm hais tias lawv muab cov keeb kwm sib txawv, lawv sib txawv hauv cov qauv, cov khoom, thiab kev siv.Noj qab haus huv^®yog achaw tsim tshuaj paus thiab tsumntawm gallnut extract, muab koj nrog siab -zoo gallic acid thiabtannic acid. Raulag luam wholesalenug, thov koj xav tias dawb rautiv tauj pebntawminfo@kintaibio.com.

Gallic acid thiab tannic acidyog ob qho tib si ib txwm tshwm sim polyphenolic tebchaw, dav pom nyob rau hauv ntau yam nroj tsuag xws li gallnut, tara, thiab tshuaj yej. Gallic acid yog ib qho yooj yim me me - molecule phenolic acid nrog cov tshuaj formula C₇H₆O₅, feem ntau tshwm li cov hmoov dawb los yog daj me ntsis crystalline hmoov, yooj yim soluble hauv dej kub. Nws yog ib lub tsev thaiv ntawm ntau complex polyphenols.

Tannic acidyog ib tug complex macromolecular compound. Chemically, nws yog ib tug siab -molecular- hnyav compound tsim los ntawm ester bond ntawm qabzib thiab gallic acid, nrog ib tug molecular hnyav li 1701.21 thiab cov mis molecular C₇₆H₅₂O₄₆. Nws feem ntau yog daj ntseg daj rau lub teeb xim av amorphous hmoov nrog lub zog astringent saj, maj mam darkening nyob rau hauv cov xim thaum raug huab cua.

Txawm tias muaj kev sib raug zoo,Gallic acid thiab tannic acidtxawv feem ntau hauv lawv cov qauv thiab cov khoom siv tshuaj. Qhov tseem ceeb tshaj qhov sib txawv yog nyob rau hauv lawv qhov hnyav molecular. Gallic acid yog ib tug me me molecule nrog ib tug molecular hnyav ntawm tsuas yog 170.12, thaum tannic acid yog ib tug loj polymer nrog ib tug molecular hnyav ntau tshaj kaum npaug ntawm gallic acid. Qhov kev sib txawv ntawm cov qauv no ncaj qha ua rau lawv cov khoom sib txawv heev.

Chemically, tannic acid qhia lub peev xwm los khi rau cov proteins. Nws tuaj yeem khi rau cov proteins los ua dej -insoluble precipitates, uas yog lub hauv paus rau nws siv los ua tus neeg sawv cev tanning hauv tawv thiab hauv cov tshuaj ib txwm siv rau astringency thiab hemostasis. Txawm hais tias gallic acid kuj muaj kev ua haujlwm lom neeg, nws cov txiaj ntsig hauv qhov no yog qhov muaj zog tsawg dua li ntawm tannic acid.

Lawv cov tshuaj tiv thaiv antioxidant kuj txawv me ntsis. Cov kev tshawb fawb qhia tau hais tias nyob rau hauv tej yam kev mob (xws li muaj tooj liab ions), tannic acid tuaj yeem ua lub zog antioxidant kom tshem tawm cov dawb radicals thiab kuj tseem tuaj yeem ua rau muaj zog pro- oxidative kev ua ub no, tsim hydroxyl radicals zoo dua, thaum tseem muaj zog tiv thaiv DNA. Cov yam ntxwv no ua rau muaj kev sib txawv hauv lawv cov kev siv.

Gallic acid yog hailed raws li ib tug haib ntuj antioxidant. Nws zoo tshem tawm cov dawb radicals, inhibits lipid peroxidation, thiab tiv thaiv cov hlwb los ntawm oxidative kev nyuaj siab puas. Tsis tas li ntawd, nws nthuav tawm cov tshuaj tiv thaiv - mob, tshuaj tua kab mob, tshuaj tua kab mob, thiab txawm tias muaj peev xwm tiv thaiv kab mob thiab cov teebmeem neuroprotective. Cov txiaj ntsig sib txawv no ua rau nws nrhiav tau zoo hauv kev lag luam tshuaj thiab khoom noj khoom haus.

Tannic acid, ntawm qhov tod tes, muaj ntau yam teebmeem. Dhau li ntawm nws cov khoom antioxidant, nws cov yam ntxwv tseem ceeb tshaj plaws yog astringency thiab antibacterial zog. Nws tuaj yeem coagulate cov protein, yog li ua lub luag haujlwm hauv hemostasis, tshuaj tiv thaiv kab mob, thiab tiv thaiv mucous daim nyias nyias. Tsis tas li ntawd, industrially, nws yog siv los ua tawv tanning tus neeg sawv cev los hloov cov tawv hides rau hauv tawv, muaj nuj nqigallic acidhloov tsis tau. Nws kuj tseem tuaj yeem tsim cov txheej txheem nrog cov hlau ions hauv dej, ua raws li cov nplai inhibitor thiab dispersant, thiab yog li muaj kev siv hauv kev kho dej.

Gallic acidfeem ntau yog siv rau hauv siab -tus nqi- ntxiv cov tshuaj zoo thiab tshuaj. Nws yog ib qho tseem ceeb raw khoom rau synthesizing propyl gallate (PG) thiab lwm yam esters, ib tug series ntawm cov zaub mov antioxidants, thiab yog dav siv los tiv thaiv rancidity nyob rau hauv cov roj thiab cov khoom noj. Hauv kev lag luam tshuaj, nws yog siv los ua cov khoom siv raw hauv cov tshuaj antioxidant thiab astringent formulations; nyob rau hauv cov tshuaj pleev ib ce, nws yog ntxiv rau siab - cov khoom tu tawv nqaij kawg vim nws cov tawv nqaij dawb thiab los tiv thaiv kev laus -.

Nyob rau hauv sib piv, tannic acid muaj daim ntaub ntawv hla ob qho tib si kev lag luam thiab kev lag luam kev noj qab haus huv niaj hnub. Hauv kev siv ib txwm siv, nws tseem yog cov khoom siv tseem ceeb hauv tawv tanning thiab ink manufacturing. Hauv kev lag luam zaub mov, nws yog sivd raws li tus neeg sawv cev qhia meej hauv npias thiab txiv hmab txiv ntoo, ua kom cov protein ntau thiab txhim kho cov khoom pom tseeb. Hauv kev lag luam tshuaj, nws cov khoom muaj zog astringent ua rau nws muaj cov khoom xyaw classic rau kev kho mob raws plab, los ntshav hauv zos, thiab kub hnyiab. Nyob rau hauv xyoo tas los no, nrog kev nce ntawm cov khoom xyaw ntuj, tannic acid kuj tau txais nws qhov chaw nyob hauv cov khoom siv tshuaj txhua hnub, ntxiv rau cov tshuaj zawv plaub hau thiab tshuaj txhuam hniav los tiv thaiv cov plaub hau thiab cov pos hniav los ntawm nws cov khoom astringent.

Gallic acidtau dav lees paub tias yog cov khoom noj khoom haus muaj kev nyab xeeb thiab cov khoom siv tshuaj pleev ib ce, thiab nws siv nyob rau hauv qhov kev txiav txim siab ntau yog txhim khu kev qha. Kev nyab xeeb ntawm tannic acid, txawm li cas los xij, yuav tsum tau ua tib zoo xav. Lub Koom Haum Koom Tes FAO/WHO Cov Kws Tshaj Lij Tshaj Lij rau Khoom Noj Ntxiv (JECFA) tau soj ntsuamtannic acidthiab tau tsim ib qho "unspecified" Txais Kev Noj Qab Haus Huv Txhua Hnub (ADI), yog tias nws yog siv los ua kev pabcuam thiab raug tshem tawm ntawm cov khoom noj khoom haus zaum kawg. Qhov no qhia tias nws siv los ua ib qho ntxiv yuav tsum nruj me ntsis ua raws li GMP cov cai. Toxicological cov ntaub ntawv qhia tau hais tias qhov nruab nrab lethal koob tshuaj (LD50) ntawm tannic acid nyob rau hauv nas yog 360 mg / kg ntawm intraperitoneal txhaj thiab 130 mg / kg ntawm txhaj tshuaj intravenously. Kev saib xyuas yuav tsum tau ua kom tsis txhob nqus tau thiab tiv nrog daim tawv nqaij thiab qhov muag, vim nws yog ib qho mob me me mus rau qhov hnyav heev. Rau cov neeg yuav khoom B2B, xaiv cov khoom lag luam uas ua raws li lub teb chaws lossis thoob ntiaj teb cov qauv (xws li USP thiab FCC) yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab ua raws.
