摘要： High-speed countercurrent chromatography (HSCCC) was used for the separation of quadri-terpenic acids from the fruit of Ligustrum lucidum Ait using a two-phase solvent system composed of hexane/ethyl acetate/methanol/water (3:6:2:1, v/v). From 250mg of the crude extract, the method yielded 87 mg of oleanolic acid at 91.5% purity and 58 mg of ursolic acid at 93.2% purity in about 2.5 h.
