Separation of hydroxyanthraquinones by chromatography

چکیده
Было изучено хроматографическое поведение гидроксиантрахинонов. Хорошее разделение было достигнуто при использовании предложенных новых хроматографических систем: бумажная хроматография смесью уксусной кислоты и воды на простой бумаге или бумаге импрегнированной оливковым мас лом, тонкослойная хроматография на целлюлозе импрегнированной диметилформамидом и на силикагеле без или с импрегнацией щавелевой или борной кислотами.

Preparative isolation and purification of hydroxyanthraquinones and cinnamic acid from the chinese medicinal herb Rheum officinale Baill. by high-speed counter-current chromatography.
A high-speed counter-current chromatography (HSCCC) method for preparative separation and purification of five hydroxyanthraquinones and cinnamic acid from the Chinese medicinal herb Rheum officinale Baill. was developed by using pH-gradient elution. The purities of rhein, emodin, aloe-emodin, chrysophanol, physcion and cinnamic acid were all over 98%, as determined by high performance liquid c...
متن کاملSimultaneous determination of hydroxyanthraquinones in rhubarb and experimental animal bodies by high-performance liquid chromatography.
A simple and reliable high-performance liquid chromatographic (HPLC) method was developed for the simultaneous determination of five hydroxyanthraquinones (aloe-emodin, rhein, emodin, chrysophanol, and physcion) in Rhubarb and experimental animal bodies. A Zorbax SB-C18 column (250 mm x 4.6 mm i.d., 5 microm) and a methanol-0.5% acetic acid (85:15, v/v) mobile phase were used for the separation...
متن کاملSimulation of Separation of a Racemic Mixture of Ibuprofen by Supercritical Fluid Chromatography in Simulated Moving Bed
Separation of a racemic mixture of ibuprofen at a low concentration level by supercritical fluid chromatography in a simulated moving bed (SFC-SMB) is investigated by simulation. The feasibility of ibuprofen enantiomers separation has been experimentally examined in the literature. Our simulation results show that separation of ibuprofen enantiomers is feasible by this method, and R-ibuprofen a...
متن کاملSeparation of Biojenic Amines Using Dansyl Cloride Derivatization and Mixed Micellar Liquid Chromatography
Separation of some biogenic amines via RP-HPLC using mixed micellar mobile phase was investigated. The compounds were derivatized before hand by dansyl chloride as a chromophoric reagent. Appropriate conditions for separation, were determined by studying factors such as temperature, type and percentage of organic modifier, concentration of surfactants (SDS and Brij-35) and the pH of the mob...
متن کاملSeparation of Sedative – Hypnotic Drugs with Mixed Micellar Liquid Chromatography
Separation of ten sedative- hypnotic drugs was performed by RP-HPLC using mixed micellar mobile phase. Effect of temperature, type and amount of organic modifier in mobile phase on efficiency (N) and asymmetry factor (B/A) showed that, the appropriate conditions for a good separation were 35°C and 7% (V/V) butanol in mobile phase. Variations of selectivity factor versus butanol concent...
