Xadka Microbial
Alaabtan waa in la qaataa oo la kormeeraa si waafaqsan sharciga (Mabaadi'da Guud 1105 iyo 1106).Tirada guud ee bakteeriyada aerobic per lg ee alaabta tijaabada ah waa in aanay ka badan 100cfu, wadarta tirada caaryada iyo khamiirku waa in aanay ka badan 100cfu, E. Coli waa in aan la ogaan.
Go'aaminta nuxurka
Lagu cabbiray chromatography dareere waxqabadka sare leh (Guud 0512).
Xaaladaha Chromatographic iyo ku habboonaanta nidaamka tijaabada siddeed iyo toban alkyl silane- bonded jel silica ayaa loo isticmaalay buuxin ahaan;Water-methanol (85: 15) ayaa loo isticmaalay sidii marxalad wareeg ah;Waxaana cabirka lagu sameeyay qalab wax bare index refractive kala duwan.Lambarka saxanka aragtida kama yara 1500 oo loo xisaabiyay sida ugu sarreysa betal cyclodextrin.
Habka go'aaminta: qaado qiyaastii 50mg ee alaabtan, si sax ah u miisaan, ku rid weel 10ml ah oo cabbir ah, ku dar qadar ku habboon oo biyo ah si aad u milmaan oo u milo miisaanka, si fiican u rux, oo u isticmaal xal tijaabo ah, 10/xl si sax ah ayaa loogu duray chromatograph-ka dareeraha ah, chromatogram-kana waa la duubay.50mg kale oo ka mid ah walaxda tixraaca ee betaloc cyclodextrin ayaa si sax ah loo cabbiray, qaab la mid ah ayaa loo isticmaalay go'aaminta.Marka loo eego habka caadiga ah ee dibadda si loo xisaabiyo aagga ugu sarreeya, taas oo ah.
