[Objective] To isolate and purify phenolic constituents from Nymphaea candida Presl by high-speed counter-current chromatography( HSCCC). [Methods] HSCCC was employed to separate phenolic compounds from N. candida with two steps. Two solvent systems were ethyl acetate ∶ methanol ∶ water( 4 ∶ 1 ∶ 5) and ethyl acetate ∶ n-butanol ∶ water( 4 ∶ 1 ∶ 5). HSCCC was executed under the conditions of2. 0 m L / min flow rate,850 r / min rotation speed and 254 nm detection wavelength. The purities of compounds were det...
