Profiling and Isolation of Ten Rare Branched-Chain Alkylresorcinols in Quinoa

Molecules, 2023
Alkylresorcinols (∑ARs) are bioactive lipid compounds predominantly found in cereals. These amphiphilic compounds exist in a high structural diversity and can be divided into two main groups, i.e., 5-alkylresorcinols (ARs) and 2-methyl-5-alkylresorcinols

Carnosol purification. Scaling-up centrifugal partition chromatography separations [PDF]

Journal of Chromatography A, 2016
This paper illustrates the application of a recently proposed protocol allowing the scale-up prediction on hydrostatic countercurrent chromatography columns (centrifugal partition chromatographs or CPC). A commercial extract of rosemary (Rosmarinus officinalis L.) was used as the starting material containing 0.48% of carnosol, an active pharmaceutical ...
