Abstract: In our present study, two groups of xanthones isomers (1-hydroxy-3,5,8-trimethoxyxanthone and 1-hydroxy-3,7,8-trimethoxyxanthone; 1,8-dihydroxy-3,7-dimethoxyxanthone and 1,8-dihydroxy-3,5-dimethanolxanthone) and other two xanthones (3-methoxy-1,5,8-trihydroxyxanthone and 3,5-dimethoxy-1-hydroxyxanthone) were separated from Swertia franchetiana. First, a solvent system composed of petroleum ether/methanol/water… read more here.

DOI: 10.1002/jssc.201700851
Abstract: An effective high-speed countercurrent chromatography method was successfully established by using ionic liquids as the modifier of the two-phase solvent system. Adding a small amount of ionic liquids significantly shortens the separation time and improves… read more here.
