Purification of Sesquiterpenes from Saussurea LappaRoots by High Speed Counter Current Chromatography
Sesquiterpenes lactones including costunolide and dehydrocostus lactone, were isolated from Saussurea lappa roots, which had exhibited a wide range of biological activities such as anti-cancer, anti-inflammatory, antiulcer, and immunomodulatory activities. High-speed counter-current chromatography (HSCCC) was applied for the rapid preparative isolation of sesquiterpenes lactones from <...

متن کاملCounter-current chromatography using hexane/surfactant-containing water solvent systems.
We developed a n-hexane/surfactant-containing water solvent system in counter-current chromatography (CCC) in order to separate hydrophobic compounds. By using the upper phase as the mobile phase, we have separated steroid samples. Retention times of steroids progesterone and delta4-androstene-3,17-dione increased slightly by increasing the concentration below the critical micellar concentratio...
متن کاملSample capacity in preparative high-speed counter-current chromatography.
High-speed counter-current chromatography (HSCCC) is a versatile technique in preparative separation and purification of pure compounds from complex matrices. As a preparative chromatography, there is a need to maximize the column production. Based on the plate theory of Van Deemter, the effect of the sample load on the separation was investigated in a preparative HSCCC with a 1000 ml column ca...
متن کاملPreparative Separation of Polyphenols from Artichoke by Polyamide Column Chromatography and High-speed Counter-current Chromatography
An efficient method for the rapid separation and purification of polyphenols from artichoke by polyamide column chromatography in combination with high-speed counter-current chromatography (HSCCC) was successfully built. The crude ethanol extracts from dry artichoke were first pre-separated by polyamide column chromatography and divided in two parts as sample 1 and sample 2. Then, the samples w...
