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.
