Compared with those of crude Fructus Corni, the chemical components of the processed Fructus Corni were changed both in quality and in quantity. From the ESI-MS spectra of the crude and processed Fructus Corni, six peaks were selected to establish the characte-ristic ESI-MS peaks. Several factors in the processing procedure were examined. The experimental results demonstrate that the chemical reactions that occurred in the processing procedure can be used for the elucidation of the processed mechanism of Fructus Corni, which is regularly affected by the processing conditions. The present article provides both the chemistry evidence for the understanding of the processing procedure of Fructus Corni and the specific methodology for the research of the processing procedure and quality identification of traditional Chinese medicine.展开更多
