Effect of operating parameters on a centrifugal partition chromatography separation [PDF]

Journal of Chromatography A, 2016
Centrifugal partition chromatography (CPC) is the branch of countercurrent chromatography (CCC) that works with single axis hydrostatic columns with rotary seals. The hydrodynamic of the liquid stationary phase-liquid mobile phase equilibrium in the CPC chambers has been studied theoretically and with specially designed CPC columns.

Prediction of Bleeding via Simulation of Hydrodynamics in Centrifugal Partition Chromatography

Separations
Centrifugal Partition Chromatography (CPC) utilizes a two-phase liquid–liquid system as mobile and stationary phases. During operation, the latter continuously drains out of the rotor, despite it being in fact stationary, leading to decreasing separation

Isolation of Alkaloids from Sinomenium acutum by Centrifugal Partition Chromatography and Their Ameliorating Effects on Dexamethasone-Induced Atrophy in C2C12 Myotubes

Separations, 2023
Bioactivity-guided isolation was conducted using centrifugal partition chromatography (CPC) from an extract of Sinomenium acutum rhizome, which has shown promising preventive effects in a dexamethasone-induced C2C12 myotube atrophy model.

Isolation of Methoxyfuranocoumarins FromAmmi majusby Centrifugal Partition Chromatography [PDF]

Journal of Chromatographic Science, 2015
Pure methoxyfuranocoumarins were isolated from Ammi majus L. by use of low-pressure column chromatography (LPCC) followed by centrifugal partition chromatography (CPC). The concentrated petroleum ether extract from fruits of A. majus was fractionated on a silica gel column using a gradient of ethyl acetate in dichloromethane (0-80%, v/v). Coumarin-rich

Centrifugal partition chromatography of grayanane compounds.

Journal of the agricultural chemical society of Japan, 1985
A centrifugal partition chromatographic method was developed for separation of grayanotoxin (G)-I, G-II and G-III, which are toxic diterpenoids of Leucothoe grayana MAX. The optimum conditions for separating these grayanotoxins from each other utilized the following: solvent composition, CHCl3:MeOH:H2O=45:60:40 (mobile phase, upper layer; stationary ...

Preparative Separation of Acylglycerol by Centrifugal Partition Chromatography (CPC)

Journal of Japan Oil Chemists' Society, 1992
Reacted mixtures obtained by the esterification of three purified fatty acids (oleic acid, icosapentaenoic acid, and docosahexaenoic acid) with glycerol were separated and purified into triacylglycerol, diacylglycerol, monoacylglycerol, and free fatty acid fractions by centrifugal partition chromatography (CPC).Two solvents were used in combination for
