Kev ntsuam xyuas ntawm Hydroxyanthracenes hauv Rheum extract ntawm HPLC
Oct 21, 2017

Kev Txiav Txim ntawm Cov Lus

Chromatographic mob thiab kev soj ntsuam ntawm qhov system:

Txiav Phom: Methanol: Dej: glacial acetic acid = 79.5: 19.5: 1

Yoj ntev: 254nm

Chromatographic Sab: C18 (4.6 MM × 150mm, 5μm)

(Raws li txoj kev sim ntawm emodin hauv Suav Pharmacopoeia 2005)

 

Txheem kua

Qhov hnyav yog 2mg Emodin txheem , Rhein txheem , aloe-emodin txheem , chrysophanol txheem thiab physcion txheem Separately, cais ntxiv rau ib 25mL volumetric hwj, ntxiv cov nqi acetone yaj, Ultrasonic yoj yog shaken txog tag nrho dissolve nyob rau hauv acetone. Tom qab ntawd ntxiv acetone rau scale mark, tau 5 qauv tov.

 

Kev daws teeb meem

Qhov hnyav yog 10mg rhawv tshem cov qauv, kom muaj 25m volumetric hwj, ntxiv cov roj acid ntau kom yaj, Ultrasonic yoj yog shaken txog tag nrho cov yaj hauv cov acetone, Mam li ntxiv acetone nplua, ntsuas tusyees, nws tau.

 

Txuas ntxiv tov sib npaug zos (li 20 lub hli) ntawm Standard Preparation thiab Kev Tshawb Fawb npaj rau hauv cov chromatograph, sau cov chromatograms, thiab ntsuas cov lus teb rau cov lus tseem ceeb.

A1 W2

X% = ----- × ---- × 100%

A2 W1

Nyob rau hauv uas yog A1 qhov kev ntsuam xyuas kev ntsuam xyuas, A2 yog tus qauv qhov siab tshaj, W2 yog cov concentration ntawm tus qauv, W1 yog qhov concentration of assay sample.
