| titleOfInvention | Full two-dimensional liquid phase separation method for dendrobium nobile lindl |
| abstract | The invention relates to the technical field of separation of active ingredients in natural medicines, and provides a full two-dimensional liquid phase separation method for dendrobe, aiming at solving the problems of complicated procedures, toxic solvent use, low extraction efficiency and recovery rate of the traditional dendrobe extraction method, which comprises the following steps: (1) pulverizing herba Dendrobii, and sieving with a third sieve to obtain herba Dendrobii powder; (2) extracting the dendrobium powder by adopting a matrix solid-phase dispersion extraction method to obtain dendrobium extract; (3) and (3) carrying out sample injection analysis and characterization on the dendrobium extract by using two-dimensional ultra-performance liquid chromatography and mass spectrometry. The invention skillfully combines the two-dimensional ultra-high performance liquid chromatography and mass spectrometry combined technology with the matrix solid phase extraction technology, and realizes convenient and efficient separation and extraction of effective components in natural products. |
