Preparative separation of nine flavonoids fromPericarpium Citri Reticulataeby preparative-HPLC and HSCCC

Separation Science and Technology, 2016
ABSTRACTAn economical and systematized chromatographic separation process to isolate and purify flavonoids from Pericarpium Citri Reticulatae was developed. Solvent refluxing extraction, macroporous resin column, preparative HPLC and HSCCC (high-speed counter-current chromatography) were used for extraction, fraction, isolation, and purification of ...

Separation of polysaccharides from Spirulina platensis by HSCCC with ethanol-ammonium sulfate ATPS and their antioxidant activities

Carbohydrate Polymers, 2017
Three separation methods for water-soluble polysaccharides from Spirulina platensis (PSP) were compared, including sevage deproteinization and column chromatography, ethanol-ammonium sulfate aqueous two-phase system (ATPS) and column chromatography, and one-step high speed counter-current chromatography (HSCCC) with ethanol-ammonium sulfate ATPS.
