Ukucoceka kweChromatographic-Nyibilikisa ubungakanani obulinganiswe ngokuchanekileyo beChloramphenicol kwimethanol ukuze ufumane isisombululo sovavanyo esine-10 mg nge-mL nganye.Lungiselela isisombululo se-USP Chloramphenicol RS kwi-methanol equkethe i-10 mg nge-mL (Isisombululo esiqhelekileyo A).Nciphisa izahlulo zesisombululo esiMgangatho A ngokobuninzi ngemethanol ukufumana isisombululo esiseMgangathweni B esiqulathe i-100 µg ngemL kunye nesinyibiliko soMgangatho C esiqulethe i-50 µg ngemL.Faka iinxalenye ezahlukeneyo ze-20-µL zesisombululo sovavanyo kunye nezisombululo eziMgangatho B kunye no-C kwipleyiti ecekethekileyo yechromatographic (bona iChromatography 621), eqatywe nge-0.25-mm yomxube wejeli ye-chromatographic.Phuhlisa ichromatogram kwinkqubo yokunyibilikisa equka umxube wekloroform, i-methanol, kunye ne-glacial acetic acid (79:14:7) de i-solvent front ihambe malunga nesithathu-esine yobude beplate.Susa ipleyiti kwigumbi, i-air-dry, kwaye uhlolisise phantsi kokukhanya okufutshane kwe-UV: nayiphi na indawo ngaphandle kwendawo eyintloko efunyenwe kwisisombululo sovavanyo ayigqithisi ngobukhulu okanye ubukhulu bendawo ephambili efunyenwe kwisisombululo esisemgangathweni B (1% ), kunye nesixa sobumdaka obumelwe ngawo onke amabala ngaphandle kwendawo ephambili, esekelwe kuthelekiso lokuqina kwaloo mabala kunye nokuqina kweendawo eziphambili ezifunyenwe kwizisombululo zoMgangatho B no-C, azidluli kwi-2% .
Isivavanyi-
Isigaba seselula-Lungisa umxube ococekileyo ococekileyo wamanzi, i-methanol, kunye ne-glacial acetic acid (55: 45: 0.1).Yenza uhlengahlengiso xa kukho imfuneko (jonga ukufaneleka kweNkqubo phantsi kweChromatography 621).
Ulungiselelo olusemgangathweni- Nyibilikisa isixa esinomlinganiso ochanekileyo we USP Chloramphenicol RS kwisigaba seMobile, kwaye unyibilike ngokobuninzi, kwaye ulandele inyathelo xa kukho imfuneko, ngesigaba seMobile ukufumana isisombululo esinoxinzelelo olwaziwayo malunga nama 80 µg ngemL.Hluza inxalenye yesi sisombululo nge-0.5-µm okanye isihluzo esicolekileyo se-porosity, kwaye usebenzise isihluzo esicacileyo njengolungiselelo loMgangatho.
Ukulungiswa kwe-Assay- Dlulisa malunga ne-200 mg ye-Chloramphenicol, ilinganiswe ngokuchanekileyo, kwi-flask ye-volumetric ye-100-mL, yongeza isigaba se-Mobile kwivolumu, kwaye udibanise.Dlulisa i-4.0 mL yesisombululo esisiphumo kwi-flask ye-volumetric ye-100-mL, i-dilute kunye nesigaba se-Mobile ukuya kumthamo, kwaye udibanise.Hluza inxalenye yesi sisombululo nge-0.5-µm okanye isihluzo se-porosity esicolekileyo, kwaye usebenzise isihluzo esicacileyo njengolungiselelo lwe-Assay.
Inkqubo yeChromatographic (jonga i-Chromatography <621>)-I-chromatograph yolwelo ixhotyiswe nge-280-nm detector kunye nekholamu ye-4.6-mm × 10-cm equlethe i-5-µm yokupakisha i-L1.Izinga lokuhamba malunga ne-1 mL ngomzuzu.I-Chromatograph Ukulungiswa koMgangatho, kwaye urekhode iimpendulo eziphakamileyo njengoko zichazwe phantsi kweNkqubo: ukusebenza kakuhle kwekholomu kugqitywe kwincopho ye-analyte ayikho ngaphantsi kwe-1800 yamacwecwe eethiyori, i-tailing factor ayikho ngaphezu kwe-2.0, kunye nokuphambuka okusemgangathweni ohambelanayo kwi-injection ephindaphindayo ayikho. ngaphezu kwe-1.0%.
Inkqubo--[Qaphela-Sebenzisa umphakamo ophakamileyo apho iimpendulo eziphezulu zibonisiwe.] Ngokwahlukileyo tofa imiqulu elinganayo (malunga ne-10 µL) yoLungiselelo oluMgangatho noLungiselelo loVavanyo kwichromatograph, urekhode iichromatogram, kwaye ulinganise iimpendulo zeencopho ezinkulu.Bala ubuninzi, kwi-mg, ye-C11H12Cl2N2O5 kwisahlulo seChloramphenicol esithathwe ngefomula:
2.5C(rU / rS)
apho uC lugxininiso, kwi-µg ngemL, ye-USP Chloramphenicol RS kulungiselelo loMgangatho, kunye ne-rU kunye ne-rS ziimpendulo eziphezulu ezifunyenwe kulungiselelo loVavanyo kunye nolungiselelo loMgangatho, ngokulandelelanayo.
