Application of High Speed Countercurrent Chromatography (HSCCC) to the Isolation of Kavalactones

Journal of Liquid Chromatography & Related Technologies, 2005
Abstract High speed countercurrent chromatography (HSCCC) was used to isolate the major kavalactones kavain, 7,8‐dihydrokavain, methysticin, 7,8‐dihydromethysticin, yangonin, and demethoxyyangonin. An ethanolic crude extract of kava root was subjected to HSCCC separation. Due to the presence of polymeric material, the sample load was limited.

Preparation and Purification of Epigallocatechin by High‐Speed Countercurrent Chromatography (HSCCC)

Journal of Liquid Chromatography & Related Technologies, 2004
Abstract Epigallocatechin (EGC) was prepared by the degallation of Epigallocatechin‐O‐3‐gallate (EGCG). EGCG was completely converted to EGC and gallic acid by adding 4 mg tannase/100 mg EGCG at the concentration of 2 mg/mL under pH 6.0, at 35°C for 30 min.
