This study describes the rapid separation of mulberry anthocyanins; namely, cyanidin‐3‐glucoside and cyanidin‐3‐rutinoside, using high‐performance countercurrent chromatography, and the establishment of a volumetric scale‐up process from semi‐preparative to preparative‐scale. To optimize the separation parameters, biphasic solvent systems composed of tert‐butyl methyl ether/n‐butanol/acetonitrile/0...
High‐performance countercurrent chromatography (HPCCC) with electrospray light‐scattering detection was applied for the first time to isolate a spirostanol and a novel furostanol saponin from Liriope platyphylla. Due to the large differences in KD values between the two compounds, a two‐step HPCCC method was applied in this study. The primary HPCCC employed methylene chloride/methanol/isopropanol/water...
