Slow rotary countercurrent chromatography (SRCCC) was used for the separation of saponins from towel gourd crude extract (Luffa cyclindria Roem.) with a biphasic solvent system composed of chloroform-methanol-water (13:7:8, v/v). In each separation of SRCCC, 3 g crude saponins sample yielded 357 mg Lucyoside Q (1) and 213 mg Lucyoside H (2). The structures of the two compounds were confirmed by means of ESI-MS, 1 H- and 13 C-NMR.
