| titleOfInvention | A method for preparing Chinese medicinal extract with anti-tumor effect by high-speed countercurrent chromatography |
| abstract | The invention relates to the technical field of traditional Chinese medicines, and particularly discloses a method for preparing a traditional Chinese medicine extract with an anti-tumor effect by using a high-speed counter-current chromatography technology. Comprises the following steps: (1) extracting the traditional Chinese medicine material of the zornia gibbosa with alcohol, concentrating the extracting solution and removing the solvent to obtain zornia gibbosa alcohol extract; (2) adding water to the alcohol extract of the zornia gibbosa for suspension, sequentially extracting with chloroform and ethyl acetate for 1-3 times respectively, taking an ethyl acetate extraction part, and concentrating to remove an ethyl acetate solvent to obtain an ethyl acetate extract; (3) separating the ethyl acetate extract by high-speed counter-current chromatography to obtain the Chinese medicinal extract. The Chinese medicinal extract prepared by the method has effects of resisting lung cancer and nasopharyngeal carcinoma; especially has more obvious effect on nasopharyngeal carcinoma. |
