| titleOfInvention | Extracting and separating method of hedyotiscone A in corymbose hedyotis herb |
| abstract | The invention relates to an extracting and separating method of hedyotiscone A in corymbose hedyotis herb. The method includes the steps of extracting corymbose hedyotis herb through alcohol solvent, repeatedly extracting for multiple times through petroleum ether, n-butyl alcohol and ethyl acetate, concentrating to obtain refined extract, dissolving the refined extract in methyl alcohol through ultrasonic waves, conducting filtering, chromatographing filtrate through a positive-phase silica gel column, and further purifying through a column chromatography separation method or preparation liquid phase separation method or scraper method to obtain hedyotiscone A. By means of the method, the yield of separating hedyotiscone A in corymbose hedyotis herb is high, and the method is easy, convenient and rapid to implement and high in purity; the obtained hedyotiscone A can be used for preparing anti-tumor auxiliary medicine, and certain application value is provided for research and development of anti-cancer medicine. |
