DOLOČITEV SITOSTEROLA ALI STIGMASTEROLA V MASLU ALI ZGOŠČENEM MASLU S KAPILARNO-PLINSKO KROMATOGRAFIJO
The method describes a procedure for the quantitative determination of sitosterol or stigmasterol in butter and concentrated butter.
Metoda opisuje postopek za količinsko določanje sitosterola ali sigmasterola v maslu in zgoščenem maslu.
Sitosterol is taken to be the sum of β-sitosterol and 22 dihydro-β-sitosterol, other sitosterols are assumed to be insignificant.
Za sitosterol se vzame vsota β-sitosterola in 22-dihidro-β-sitosterola, za druge sitosterole se predpostavlja, da so nepomembni.
The butter or concentrated butter is saponified with potassium hydroxide in ethanolic solution and the unsaponifiables are extracted with diethyl ether.
Maslo ali zgoščeno maslo se umili v etanolski raztopini kalijevega hidroksida, snovi, ki jih ni mogoče umiliti, se ekstrahirajo z dietiletrom.
The sterols are transformed into trimethyl-silyl ethers and are analysed by capillary-column gas chromatography with reference to an internal standard/betulin.
Steroli se preoblikujejo v trimetil-silil etre in se analizirajo s kapilarno-kolonsko plinsko kromatografijo glede na interni standard/betulin.

Odstranite spodnji vodni sloj in s stresanjem sperite sloj etra s štirimi zaporednimi 100 ml alikvoti vode.
Note 2: To avoid formation of an emulsion, it is essential that the first two water washes are carried out gently (10 inversions).
Opomba 2: Da se prepreči nastanek emulzije, je bistveno, da se prvi dve izpiranji z vodo opravita počasi (10 vrtljajev).
The third wash can be shaken vigorously for 30 seconds.

Incomplete silylation of betulin is indicated by a second peak close to that of betulin.
Nepopolna sililacija betulina se pokaže kot drugi vrh poleg vrha betulina.
The presence of ethanol at the silylation stage will interfere with silylation.
Prisotnost etanola v fazi sililacije moti sililacijo.
This may result from inadequate washing at the extraction stage.
To je lahko posledica nezadostnega spiranja v fazi ekstrakcije.
If this problem persists, a fifth wash may be introduced at the extraction stage, shaking vigorously for 30 seconds.
Če se ta težava pojavlja, se v fazi ekstrakcije lahko uvede peto spiranje s 30-sekundnim močnim stresanjem.

Inject 1 μl of silylated standard solution (stigmasterol or sitosterol) and adjust the integrator calibration parameters.
Vbrizgajte 1 μl sililizirane standardne raztopine (stigmasterola ali sitosterola) in prilagodite kalibracijske parametre integratorja.

Inject 1 μl of silylated sample solution and measure peak areas.
Vbrizgajte 1 μl raztopine sililiziranega vzorca in izmerite površino vrhov.
Each chromatographic run must be bracketed by an injection of standards.
Vsaka kromatografska serija mora biti omejena z vbrizganjem standardov.

Determine the area of the sterol peaks and betulin peaks in both standards bracketing a batch, and calculate R1:
Določite površino vrhov sterola in vrhov betulina v obeh standardih, ki omejujeta serijo vzorcev, ter izračunajte R1:
= (average area of the sterol peak in the standard)/(average area of the betulin peak in the standard)
= (povprečna površina vrha sterola v standardu)/(povprečna površina vrha betulina v standardu)
Determine the area of the sterol peak (stigmasterol and sitosterol) and betulin peak in the sample and calculate R2:
Določite površino vrha sterola (stigmasterola in sitosterola) in vrha betulina v vzorcu ter izračunajte R2:
