Description
DESCRIPTION (provided by applicant): Recent advances in countercurrent chromatography (CCC) have created novel spiral-design separation columns that hold a very high stationary phase of all the solvent systems, such that now all molecules of any size and water solubility can be successfully separated in high-speed countercurrent chromatography. With spiral CCC there is inherent versatility, more than any type of chromatography. Preliminary studies with the new spiral tubing support rotor succeeded in purifying Sutherlandioside B, a major water soluble cycloartane glycoside from Lessertia frutescent (Sutherlandia) is using an n- butanol solvent system. With the small volume of the coil (~100 ml) and a stationary phase at 50% (~50 ml), it is impressive that amass of 1.2 g of crude plant extract could be efficiently fractionated in one run with high recovery of the target compound. In addition, the active iridoid glycoside, harpagoside was isolated from an extract of Harpagophytum procumbens (Devil's Claw
