Developments in the application of counter-current chromatography to plant analysis

Tipo de material: TextoTextoSeries ; Journal of Chromatography A, 1112(1-2), p.181-194, 2006Trabajos contenidos:
  • Marston, A
  • Hostettmann, K
Tema(s): Recursos en línea: Resumen: Counter-current chromatography is a very versatile separation technique which does not require a solid stationary phase. It relies simply on the partition of a sample between the two phases of an immiscible solvent system. Some of the more recent applications of the method to the separation of plant-derived natural products are described here. Crude plant extracts and semi-pure fractions can be chromatographed, with sample loads ranging from milligrams to grams. Aqueous and non-aqueous solvent systems are used and the separation of compounds with a wide range of polarities is possible. The technique is complementary to other chromatographic methods and is compatible with gradient systems. The possibilities for solvent selection are almost limitless but some guidelines for the choice of successful systems are presented.
