Strategies of solvent system selection for the isolation of flavonoids by countercurrent chromatography.
TL;DR: This paper proposes strategies of solvent system selection for the isolation of flavonoids by CCC, based on data from the literature, plus incorporation of own practical experiences, to show the versatility of this technique.
Journal ArticleDOI

TL;DR: A method developed for the fractionation of Schinus terebinthifolius Raddi berries dichloromethane extract was thoroughly optimized to achieve maximal throughput with minimal solvent and time consumption per gram of processed crude extract, enabling MS-target-guided isolation procedures.
Journal ArticleDOI
Changes in the mobile phase composition on a stepwise counter‐current chromatography elution for the isolation of flavonoids from Siparuna glycycarpa
TL;DR: The isolation of flavonoids and other aromatic compounds from an ethyl acetate extract of leaves of Siparuna glycycarpa using stepwise elution counter-current chromatography showed a gradual variation of the composition of the mobile phase emerging after the step gradient, favoring the selectivity of the solvent system.
Journal ArticleDOI
Schinus terebinthifolius countercurrent chromatography (Part II): Intra-apparatus scale-up and inter-apparatus method transfer
Fernanda das Neves Costa,Mariana Neves Vieira,Ian Garrard,Peter Hewitson,Gerold Jerz,Gilda Guimarães Leitão,Svetlana Ignatova +6 more
TL;DR: This unique study of three international teams is based on innovative approach to simplify the scale-up between different CCC machines using fractionation of Schinus terebinthifolius berries dichloromethane extract as a case study.
