| titleOfInvention | Method for separating quercetin rhamnoside from artemisia rupestris |
| abstract | The invention provides a method for separating quercetin 3-O-alpha-L-rhamnoside from artemisia rupestris, which comprises the following steps: fully mixing n-hexane-ethyl acetate-methanol-water (3:10:3:10 v/v), and layering to obtain an upper layer solvent and a lower layer solvent for later use; the lower solvent was removed to dissolve the ethyl acetate fraction of Artemisia ordosica, and the resulting sample solution was separated by High-speed counter-current chromatography (HSCCC). The invention adopts HSCCC to extract and separate the quercetin 3-O-alpha-L-rhamnoside with the purity of more than 90 percent from the artemisia selengensis more conveniently and quickly, and provides a new way for preparing the compound. |
