Zur elutionschromatographischen Trennung des freien und veresterten Cholesterins in Organ- und Serumfetten und direkten kolorimetrischen Bestimmung

Abstract: Die Vielzahl der vorhandenen Cholesterin-Bestimmungsmethoden (kritische Würdigung s. Schettler 1 , M er t ens und Albert 2 spricht einmal gegen die Spezifität, zum anderen aber auch für die Schwierigkeiten, reproduzierbare Ergebnisse zu erhalten. Wegen störender Beimengungen ist die direkte Bestimmung bisher nur in sehr cholesterinreichen Fetten, wie das menschliche Serumfett, ausführbar und ist dazu noch mit einem erheblichen Fehler belastet. Deswegen werden meist die Digitoninfällungsmethoden von Schönheimer… Show more

“…The separation of the free and ester bound cholesterol was performed after Schon and Gey (26) on the A120 3 column by chrom atography. The phosphorus content in the lipids was estimated by the m ethod of Ferrari (4) after destruction of the methanol-chloroform solution with sulphuric acid and hydrogene peroxide.…”

“…The determ ination of cholesterol was performed by the Libermann-Burchard reaction. The separation of the free and esterized cholesterol was carried out by chrom ato graphy on the A120 3 column after Schôn and Gey (3). For the sepa ration of cholesterol and vegetable sterols in the liver, the paper chrom atographic m ethod of Peereboom (4) was used.…”
