| titleOfInvention | A kind of method for purifying troxerutin from troxerutin waste liquid powder |
| abstract | The invention discloses a method for purifying troxerutin from troxerutin waste liquid powder. Step 2, sample loading: dissolve the troxerutin waste liquid powder with an eluent, and load the sample by wet method; step 3, elution: carry out the troxerutin waste liquid powder after wet loading in step 2. Elution, TLC analysis and detection, then collect the eluate A containing Troxerutin, concentrate under reduced pressure to obtain Troxerutin crude fraction; Step 4, dissolve the Troxerutin crude fraction obtained in Step 3 After the membrane is further separated and purified by semi-preparative high performance liquid chromatography, the eluate B containing Troxerutin is collected, concentrated under reduced pressure, and freeze-dried to obtain brown-yellow Troxerutin powder. In the present invention, the troxerutin waste liquid powder is treated by a silica gel chromatography column combined with a purification method of semi-preparative high performance liquid chromatography, and the troxerutin content reaches 98%. |
