Abstract:
UPLC-Q-Orbitrap MS/MS and ICP-MS coupled with multivariate statistical analysis was employed to explore the differences in chemical compositions of Guilingji(GLJ) before and after alchemy.The changes in organic chemical compositions and inorganic elements were observed and 39 differential organic compositions were found in GLJ after alchemy, 24 compounds of which were identified. The differential compositions of GLJ included violet ketones, chalcones, amides, and fatty acids whose contents were increased after alchemy, as well as flavones, isoflavones, dihydroflavones, flavonoid glycosides, and coumarins whose content were decreased after alchemy. This study showed 6 inorganic elements filtered out as markers for distinguishing GLJ before and after alchemy, including B, Si, Mg, K, Cr, and Ni.The contents of Mg, K, Cr and Ni were increased while the contents of B and Si were decreased after alchemy.The difference of the contents after alchemy changed the cold and hot properties of the compound, showing the decrease of dryness, and the hot property was changed to warm and neutral properties; in addition, the membrane permeability and absorption of the compound compositions were improved. In this study, we preliminarily investigated the changes of chemical compositions in GLJ before and after alchemy as well as the effects of alchemy on physical and chemical properties and cold-heat nature of GLJ, laying a foundation for further clarifying the scientific connotation of alchemy process.
