1. Taw qhia

Vitamin A acetate yog daj prismatic crystal, uas yog ib tug lipid compound, thiab nws cov tshuaj stability yog zoo dua li cov vitamin A.

Nws yog vitaminA cov khoom noj khoom haus ntxiv thiab koom nrog ntau yam txheej txheem physiological hauv tib neeg lub cev. Thaum nws tsis muaj nyob rau hauv lub cev, nws yuav ua rau lub cev tsis muaj zog ntawm tes, anemia, lub cev tsis muaj zog, kev loj hlob tsis zoo, thiab lwm yam. Yog li ntawd, vitaminA cov khoom noj khoom haus muaj zog tau siv dav hauv ntau lub tebchaws. Vitamin A acetate yog unsaturated ester, oily, yooj yim oxidized, soluble nyob rau hauv roj los yog organic hnyav, tab sis insoluble nyob rau hauv dej, thiab tsis yooj yim rau muab ntxiv rau zaub mov uniformly, yog li nws daim ntawv thov ntau yam yog txwv. Nws tuaj yeem txhim kho nws cov dej solubility thiab ruaj khov, thiab daim ntawv hloov pauv ntawm cov roj mus rau hmoov, uas yooj yim rau kev khaws cia, kev thauj mus los thiab kev ua haujlwm. Feem ntau nws yog khaws cia rau hauv nws lub thawv qub uas tsis tau qhib ntawm chav tsev kub. Tsis txhob tshav ntuj, qhov chaw tshav kub, cov pa oxygen thiab qhov chaw ntub dej. Thaum qhib, siv kom sai li sai tau.

5.Tsim txoj kev

5.1 Txoj hauv paus ntsiab lus

Cov vitamin A acetate tau yaj thiab txhaj ncaj qha mus rau hauv kab rov qab-theem chromatographic kem, sib cais los ntawm kev ntws thiab elution, thiab txiav txim siab los ntawm lub ntsuas hluav taws xob ultraviolet. Cov ntsiab lus ntawm retinyl acetate (vitamin A acetate) yog xam los ntawm cov txheej txheem sab nraud.

5.2 Siv cov xwm txheej chromatographic

5.2.1 Chromatographic kem: C18 kua chromatography kem, 150 mmX4.6 mm, particle loj 5 pμm, los yog ib tug chromatographic kem nrog tib yam kev ua tau zoo.

5.2.2 Txawb theem: methanol ntxiv dej=95 ntxiv 5 (ntim piv).

5.2.3 Nruam ceev: 1 ml / min

5.2.4 Ntsuas wavelength: 326 nm.

5.2.5 Txhaj ntim: 10 μL

5.2.6 Lub sijhawm khaws cia: Lub sijhawm khaws cia ntawm vitamin A acetate yog li 5.3 min.

5.3 Kev npaj cov qauv kev daws teeb meem

Nyhav txog {{0}}.01g ntawm cov qauv, raug rau 0.00001g, thiab muab tso rau hauv 25 mL xim av volumetric hwj. Ntxiv 15 ml. ~ -20 mL ntawm anhydrous ethylase, muab tso rau hauv ib tug ultrasonic da dej rau 2 min kom yaj nws tag, dilute nws nrog anhydrous ethylase mus tas li ntim, thiab co zoo kom tau ib tug qauv Tshuag tov. Raws li qhov concentration ntawm cov qauv, nws yog diluted nrog anhydrous ethyl cawv, lim los ntawm 0.2 μm microporous membrane, thiab siv rau kev txiav txim siab ntawm high-performance kua chromatography.

5.4 Kev npaj cov txheej txheem daws teeb meem

M-Weight 0.01g ntawm all-trans-vitamin A acetate standard khoom. Qhov tseeb rau 0.00001g, muab tso rau hauv 25 ml. xim av volumetric hwj, ntxiv 15ml-20ml. anhydrous ethanol, thiab muab tso rau hauv ib da dej ultrasonic rau 2 min kom yaj tag. Ntsuas qhov tso tawm ntim nrog kiag li ethanol, co zoo, thiab tau txais cov qauv kev daws teeb meem. Pipette ib tug npaum li cas ntawm cov qauv Tshuag tov thiab dilute tus qauv nrog kiag li ethanol raws li xav tau. Npaj cov txheej txheem nkhaus daws. Cov ntsiab lus ntawm cov qauv kev daws teeb meem tau ntsuas raws li kev ntsuas UV spectrophotometric zoo ua ntej siv.

5.5 Kev txiav txim siab

Raws li kev siv chromatographic tej yam kev mob hauv 4.2, ntsuas cov qauv kev daws teeb meem thiab cov qauv kev daws teeb meem raws li, rov txhaj tshuaj ob zaug, thiab sau cov nqi ntawm cov vitamin A acetate hauv qhov sib thooj chromatogram feem. Xam cov ntsiab lus raws li cov qauv hauv 4.6 Kev daws teeb meem:

Cov ntsiab lus ntawm retinyl acetate (vitamin A acetic acid) w2 yog xam nyob rau hauv thoob ntiaj teb units ib gram (IU/g) thiab xam raws li cov mis:

A1-- qhov nruab nrab qhov chaw siab tshaj tus nqi ntawm retinyl acetate (vitamin A acetate) hauv chromatogram ntawm cov qauv tshuaj;

c--Qhov kev daws teeb meem ntawm all-trans retinyl acetate (vitamin A acetate) tus qauv hauv thoob ntiaj teb units ib milliliter (IU/ml):

V-- qhov ntim tas mus li ntawm cov qauv kev daws teeb meem zaum kawg, chav tsev yog milliliter (ml);

A2--Qhov nruab nrab qhov chaw siab tshaj tus nqi ntawm retinyl acetate (vitamin A acetate) nyob rau hauv tus qauv tshuaj chromatogram:

m--qhov loj ntawm tus qauv, hauv grams (g).

Cov txiaj ntsig kev sim yog nyob ntawm qhov ntsuas lej ntawm qhov kev txiav txim siab sib luag. Qhov sib txawv kiag li ntawm cov txiaj ntsig ntawm ob qhov kev txiav txim siab ywj pheej tau txais nyob rau hauv cov xwm txheej rov ua dua tsis yog ntau tshaj 5 feem pua ​​​​ntawm cov lej lej.
