Abstract

Centrifugal partition chromatography (CPC) coupled with evaporative light scattering detection (ELSD) was applied to separate saikosaponins‐a and ‐c preparatively from Bupleurum falcatum roots. The two‐phase solvent system composed of ethyl acetate/n‐butanol/methanol/water (15:1:3:15 by volume) was used to yield saikosaponins‐a (36.1 mg) and ‐c (28.7 mg) from 370 mg of saponin‐rich extract. The purities of isolated compounds were 96.6 and 97.3% for saikosaponins‐a and ‐c, respectively. Structure identification of these compounds was accomplished by comparison of spectroscopic data of ESI‐MS, ^1^H NMR, and ^13^C NMR with those of previously reported values.
