摘要: Introduction - Artemisia rupestris L. is a well-known traditional Chinese medicinal plant in Xinjiang. Rupestonic acid is the main active ingredient of A. rupestris L., and has been chosen as a 'marker compound' for the chemical evaluation or quality control of A. rupestris L. and its products. Although HSCCC separation method was developed before, the separation was performed with two steps using the same solvent system, which were time-consuming and waste of the solvents. Objective - To develop a simple HSCCC method for the separation and purification of rupestonic acid in a single run. Methodology - The measurement of partition coefficient (K) was introduced to select the two-phase solvent system. The simple HSCCC method was established according to the selected solvent system for separation and purification of rupestonic acid. The purity of target compound was test by HPLC and the structure was identified by MS,(1)H NMR and (13)C NMR. Results - A total of 72.3 mg of rupestonic acid and 53.5 mg of chrysosptertin B with over 95% purity were yielded from 500 mg extracts of Artemisia rupestris L. in one-step separation. Conclusion - The rupestonic acid was separated in a single run by HSCCC. Copyright (C) 2009 John Wiley & Sons, Ltd.
