We analyzed the chemical composition of the iridoid glycosides fraction (IGF) isolated from V. ciliata and evaluated the antioxidant and hepatoprotective properties. The IGF was separated by high-speed countercurrent chromatography (HSCCC) and the main compounds were identified by ultra-performance liquid...
