With the development of science and technology, new separation techniques have been applied to the drug research gradually. Ðe spectroscopic techniques make the isolation and identificDtion of the compounds easier and more efficientTaking two dimensional nuclear magnetic resonance spectroscopy (2D-NMR) as an example, its application makes the structure elucidation of the compound more accurate and reliable. It saves the cost of drug research and development and also greatly reduces the duration of drug innovation.the new drug innovation would have the broader space for development under the guidance of the theory of Chinese medicine. Ðese things provide a basis for the inspiration from Chinese medicine.
