High-Speed Countercurrent Chromatography Separation of Compounds from Herb
Researchers from the Chinese Academy of Sciences (Guangdong, China) used high-speed countercurrent chromatography to purify two benzoxazinoid glucosides from Acanthus ilicifolius L.
Researchers from the Chinese Academy of Sciences (Guangdong, China) used high-speed countercurrent chromatography to purify two benzoxazinoid glucosides from Acanthus ilicifolius L. The spiny herb is found in the mangroves of Southeast Asia and reportedly has medicinal properties. They first used n-butanol to extract the compounds from the plant. They then used a two-phase solvent system consisting of ethyl acetate, n-butanol, and 0.5% ammonium hydroxide for the single-step countercurrent chromatography separation of the two compounds. They also developed a two-step second separation process to obtain the compounds with higher purity.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
