Efficient, Baseline Separation of Pyrethrins by Centrifugal Partition Chromatography
Pyrethrins are natural pesticides present in the oil extracted from the flowers of Chrysanthemum cinerariaefolium. They are potent ion-channel neurotoxins which have higher selective toxicity for insects compared to mammals. These phytochemicals have an exceptionally safe environmental profile and are an attractive natural alternative to organophosphate insecticides currently used in agricultur...
متن کاملCentrifugal partition chromatography (CPC): Emerging separation and purification technique for lipid and related compounds
Centrifugal partition chromatography (CPC), pioneered by Ito in 1964, is a liquid–liquid chromatography without a sorbent, requiring two immiscible solvent phases. This is basically an outgrowth of countercurrent distribution, as developed by Craig and Post (1). In the most distinct variant of CPC, one liquid phase remains stationary while the second solvent phase passes through the stationary ...
متن کاملLarge-scale separation of clavine alkaloids from Ipomoea muricata by pH-zone-refining centrifugal partition chromatography.
Centrifugal partition chromatography in the pH-zone-refining mode was successfully applied to the separation of alkaloids, directly from a crude extract of Ipomoea muricata. The experiment was performed with a two-phase solvent system composed of methyl tert-butyl ether (MtBE)-acetonitrile-water (4:1:5, v/v) where triethylamine (10 mM) was added to the upper organic stationary phase as a retain...
متن کاملA single-step isolation of useful antioxidant compounds from Ishige okamurae by using centrifugal partition chromatography
One of the main compounds in Ishige okamurae, diphlorethohydroxycarmalol (DPHC), is known to exhibit antiviral and anti-inflammatory effects. However, it has not been investigated extensively. In this study, preparative centrifugal partition chromatography (CPC) coupled with 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) online HPLC was employed for effectively separating consid...
متن کاملAnion-exchange displacement centrifugal partition chromatography.
Ion-exchange displacement chromatography has been adapted to centrifugal partition chromatography. The use of an ionic liquid, benzalkonium chloride, as a strong anion-exchanger has proven to be efficient for the preparative separation of phenolic acid regioisomers. Multigram quantities of a mixture of three hydroxycinnamic acid isomers were separated using iodide as a displacer. The displaceme...
