Abstract
A method is described for the determination of 8-methoxypsoralen in human serum using a fluorodensitometric method. The fluorescence densitometry was carried out directly on the thin layer plate. The developing fluid consisted of chloroform/methanol. In patients with psoriasis after oral application of 8-methoxypsoralen the peak serum levels are mostly found between 2 and 3 h. One milliliter serum is sufficient to determine 8-methoxypsoralen levels. The results are in accordance with those obtained with gas chromatographic methods. Es wurde eine fluorodensitometrische Methode zur Bestimmung von 8-Methoxypsoralen im menschlichen Serum beschrieben. Die Fluoreszenzdensitometrie wurde auf Dünnschichtplatten bestimmt. Als Laufmittel diente Chloroform/Methanol. Bei Psoriatikern wurde nach oraler Applikation des 8-Methoxypsoralens der maximale Serumspiegel durchschnittlich nach 2 bis 3 h gefunden. Für die Methode ist es ausreichend, 1 ml Serum zur Verfügung zu haben. Die Resultate sind in Übereinstimmung mit denen die durch gaschromatographische Methoden erhalten wurden.This publication has 7 references indexed in Scilit:
