A simple method to optimize the HSCCC two‐phase solvent system by predicting the partition coefficient for target compound

Journal of Separation Science, 2008
AbstractA simple method was developed to optimize the solvent ratio of the two‐phase solvent system used in the high‐speed counter‐current chromatography (HSCCC) separation. Some mathematic equations, such as the exponential and the power equations, were established to describe the relationship between the solvent ratio and the partition coefficient ...

Uncovering the Power of HSCCC: Separation of Diastereomeric and Regioisomeric Styrylpyrones from the Stem Bark of Goniothalamus leiocarpus

Journal of Natural Products
The plant Goniothalamus leiocarpus of the Annonaceae family is used as an alternative medicine in tropical regions. Applying high-speed counter current chromatography (HSCCC), eight new bioactive styrylpyrone isomers, including 6R,7S,8R,2'S-goniolactone B (1), 6S,7S,8S,2'S-goniolactone B (2), 6R,7R,8R,2'S-goniolactone B (3), 6R,7S,8S,2'S-goniolactone C

Comparative Study on Separation and Purification of Isoflavones from the Seeds and Sprouts of Chickpea by HSCCC.

Journal of liquid chromatography & related technologies
Chickpea is known as a plant that is rich in protein, carbohydrates, and nutrition, and its seeds and sprouts have been processed into various health foods. In the present study, four isoflavones were purified from the seeds and sprouts of chickpea by high speed countercurrent chromatography (HSCCC) using two biphasic solvent systems composed of n ...
