Preparative Separation of Alkaloids from Picrasma quassioides (D. Don) Benn. by Conventional and pH-Zone-Refining Countercurrent Chromatography
Two high-speed countercurrent chromatography (HSCCC) modes were compared by separation of major alkaloids from crude extract of Picrasma quassioides. The conventional HSCCC separation was performed with a two-phase solvent system composed of petroleum ether–ethyl acetate–methanol–water (5:5:4.5:5.5,...
