Zur Identifizierung natürlich vorkommender Vitamin D3‐Ester im Lebertran Ein Beitrag zur Vitamin D3‐Analytik

Abstract: Die aus Dorschlebertran (Gadus morrhua) auf dem Wege iiber Ausfrieren, Saulen-, Diinnschicht-und Hochdruckfliissigkeitschromatographie isolierten natiirlichen Vitamin D,-Ester erwiesen sich durch die Analyse (GC, GC/MS und HR-MS) von Spaltund Derivatisierungsprodukten als Ester der 5,8,11,14,17-Eicosapentaensaure und der 4,7,10,13,16,19-Docosahexaensaure. Die beiden Fettsauren wurden gaschromatographish als Methylester und massenspektrometrisch als Pyrrolidide identifiziert, Vitamin D, als Trimethylsilylather … Show more

“…This interest stems from the observations that vitamin D 3 in salt-water fish is esterified [38,39], and that esters (mainly palmitate, stearate, linoleate and oleate) are synthesized in rats that are fed the vitamin [40]. Human pancreatic carboxyl esterase has been shown to catalyze the esterification of vitamin D 3 with oleic acid [41], and the gastro-intestinal absorption of the palmitate ester has been studied in human neonates [42].…”
