| titleOfInvention | Method for separating teddenox A and teddenox B from fermented tea |
| abstract | The invention provides a method for separating teddenox A and teddenox B from fermented tea, which comprises the following steps: A) providing fermented tea comprising teddenox a and teddenox B; B) extracting the fermented tea with boiled water or an organic solvent to obtain an extract; C) extracting the extract with an organic solvent to obtain an extract containing teddenox a and teddenox B; D) subjecting the extract to silica gel column separation to obtain a crude isolate; and E) carrying out macroporous resin column separation on the crude isolate, wherein 5-20% ethanol or methanol aqueous solution is adopted for elution, and an eluent is collected, so that the teddenox A is obtained. The method can obtain the teddenox A and the teddenox B with high purity, and has the advantages of simple operation, low cost, few steps and easy mass production. |
