Trennung der Karotinoide und Chlorophylle mit Hilfe der Papierchromatographie

Cis-trãns Isomeric Carotenoids Vitamins A and Arylpolyenes

“…-Combination of column chromatography and countercurrent distribution: CURL (75)(76)(77). -Paper chromatography of carotenoids: GRANGAUD and GARCIA (I43), BAUER (29), LEDERER and LEDERER (278), JENSEN and JENSEN (2I3). This method has been little used for separating stereoisomeric polyenes.…”

“…[29][30]. Neo A represents a monocis form and, considering the flatness of its curve in the cis-peak region, we assign to it the 9-monocis configuration.…”

Periphyton of Freshwater Ecosystems

“…40-60°C) (2.5): acetone (2) (Bauer 1952;Hallegraeff 1976a) as the first eluent and the mixture of benzine (10): petrol ether (2.5): acetone (1): methanol (0.25) as the second eluent (Halle-293 graeff 1976a). Two dimensional chromatograms were developed using an eluent of benzine (b.p.…”

Investigations on vegetable pigments in post-glacial bed sediments of lakes

“…Strip and circular paper chromatography, columnar and thin-layer chromatography was used in order to separate the pigments from the sediment into various fractions. The methods employed being chiefly based on those described in the papers [1,2,10,20,21].…”
