Rapid identification of plant materials by wooden-tip electrospray ionization mass spectrometry and a strategy to differentiate the bulbs of Fritillaria.

摘要: The counterfeit plant products, especially by using incorrect materials in pharmaceutical industry, have become a global problem. belonging to closely related species but differing medicinal properties are difficult be identified. Here, novel and generally applicable approach identify the sources of was developed, which based on use wooden-tip electrospray ionization mass spectrometry (wooden-tip ESI-MS) multivariate statistical analysis unidentified MS features (non-targeted). Using this approach, six officinal Fritillariae Cirrhosae Bulbus had been successfully differentiated. In addition, Pallidiflorae Bulbus, common adulterant also identified strategy reported here. Compared with DNA phylogenetic trees, our provided finer resolution distinguishing Fritillaria species. By combining ESI-MS analysis, useful method developed here for rapid identification herbs, showed promising perspectives tracking supply chain suppliers.
