Capillary electrophoresis of anthraquinones from Cassia siamea.
The separation and determination of two anthraquinones, emodin and chrysophanol, and two bianthraquinones, cassiamin A and cassiamin B, were achieved by capillary electrophoresis (CE). The running electrolyte used in this method was 0.05 M hydroxypropyl-gamma-cyclodextrin in 0.1 M borate buffer (pH 9) containing 10% acetonitrile, with an applied voltage of 20 kV. Application of this technique i...
متن کاملAnthraquinones and Anthraquinone Glycosides from the Roots of Cassia multijuga*
From the ethanolic extract of the roots of Cassia multijuga two anthraquinones C15H10O4 (Qi) and C16H12O6 (Q2) and two anthraquinone glycosides C28H32O15 (Si) and C27H30O14 (S2) have been isolated. Homogeneity and purity of these compounds were established by chromatography. Anthraquinone (Qi) has been identified to be 1:3-dihydroxy-2-methyl anthraquinone (rubiadin) by standard colour reactions...
متن کاملComparative Study of Antioxidant Activities of Cassia Auriculata and Cassia Siamea Flowers

متن کاملBarakol extracted from Cassia siamea stimulates chloride secretion in rat colon.
Barakol is a purified extract of Cassia siamea, a plant that has been used as a laxative in traditional medicine. In this study, the effect of barakol on anion transport across the rat colon epithelium was investigated. Colonic epithelium was mounted in Ussing chambers and bathed with Ringer's solution. Addition of 1 mM barakol to the basolateral solution produced a slow increase in short-circu...
متن کاملA stability indicating capillary electrophoresis method for analysis of buserelin
A simple and rapid stability indicating method based on capillary zone electrophoresis has been developed and validated for the analysis of buserelin (BUS). The best separations were achieved by using a bare fused silica capillary (75 m i.d.; 65.5 cm total, 57.0 cm effective length), phosphate buffer (pH = 3.00; 26.4 mM), at 35 °C. The sample was hydrodynamically injected at 50 mbar for 5 seco...
