| titleOfInvention | A kind of purification method of dendrobium alkaloid |
| abstract | The invention belongs to the technical field of extraction and purification of natural medicines, and discloses a method for purifying dendrobium alkaloids. Perform ultrasonic extraction, filter, spin dry, dissolve with methanol formic acid to obtain a crude extract; (2) filter the crude extract to obtain a sample solution; apply the sample solution to the activated In the cation-exchange solid-phase extraction column, acid and methanol are successively used for elution, and finally an alkaline organic solvent is used for elution to obtain an eluent containing dendrobium alkaloids. The purification method has the outstanding advantages of mild reaction conditions, simple purification process, high product yield and few impurities, and has good practical value. |
