Preparative separation of lithospermic acid B from Salvia miltiorrhiza by polyamide resin and preparative high-performance liquid chromatography.
Summary of "Preparative separation of lithospermic acid B from Salvia miltiorrhiza by polyamide resin and preparative high-performance liquid chromatography."
Adsorption on polyamide resin was investigated as a means of separating lithospermic acid B (LAB) from a crude extract of the roots of the traditional Chinese medicine Salvia miltiorrhiza Bunge ("Danshen"). Variables affecting adsorption capacity (solution pH, contact time on resin, initial LAB concentration) were studied. Adsorption was strongly dependent upon the initial concentration of LAB and pH. In all conditions, the polyamide resin gave optimal adsorption of LAB at an initial concentration of 2.66mg/mL and pH <3.0. The adsorption isotherm correlated well with the Langmuir-type adsorption isotherm. Maximal adsorption capacity was calculated to be 380mg/g at pH 2.0 and 25°C. LAB purity of 85.30% could be obtained by polyamide resin adsorption followed by elution with 70% ethanol solution, and the recovery was 87.1%. After preparative HPLC, the maximum HPLC purity obtained was 99.28% with a recovery of 75.2%. This method provides an efficient and low-cost method for LAB purification for industrial applications.
