Mass spectral fragmentation pattern and spectroscopic rules of phloroglucinol constituents in plants of Dryopteris Adanson / 中草药

Dryopteris crassirhizoma mainly contains the phloroglucinol constituents, which had gained much attention for its antiviral and antitumor activities and so on. Through the analysis of many literatures, we summarized the mass spectral fragmentation pattern and spectroscopic rules of phloroglucinol constituents and their derivatives, so as to provide the reference for the structure identification of phloroglucinol constituents in the plants of Dryopteris Adanson.
