Topic Information

Dear Colleagues,

Counter-current chromatography (CCC) is a unique liquid–liquid partition chromatography. Without use of solids as support matrices, CCC eliminates many complications resulting from solid-supporting materials, such as irreversible absorption, constituent losses and deactivation, tailing of solute peaks and contamination. In addition, by comparison with other solid-support chromatography including silica column chromatography and reversed-phase liquid chromatography, CCC has more advantages such as a higher retention of a stationary phase, a better selection and more solvent-saving. Therefore, CCC has been widely employed for separation and preparation of natural and synthetic compounds from complex mixtures in many fields. In discussing this topic, we will focus on the separation and purification of bioactive natural products by CCC or CCC-involved separation techniques. Novel CCC instruments and separation methods developments are encouraged, and general reviews and experimental reports are welcome.

The development of Dai medicine is relatively slow, and Zanthoxylum has great economic and medicinal value. It is still difficult to obtain medicinal components from the low-polarity parts of Zanthoxylum belonging to Dai medicine. In this study, we introduced one simple and quick strategy of separating target compounds from the barks of Z. acanthopodium var. timbor by high-performance countercurrent chromatography (HPCCC) with an off-line anti-inflammatory activity screening mode. The development of this strategy was based on the TLC-based generally useful estimation of solvent systems (GUESS) method and HPCCC in combination. This paper presented a rapid method for obtaining target anti-inflammatory compounds. Three lignins were enriched by HPCCC with an off-line inhibition mode of nitric oxide production in lipopolysaccharide-stimulated RAW264.7 macrophage cells, using petroleum ether–ethyl acetate–methanol–water (3:2:3:2) as the solvent system. The results showed that this method was simple and practical and could be applied to trace the anti-inflammatory components of the low-polarity part in Dai medicine. Full article
