Objective To investigate the pharmacodynamic substance basis and molecular mechanism of Polygonatum sibiricum against tumor diseases. Methods The chemical components of Rhizoma Polygonatum were collected by TCMSP platform, and the properties of ADME were predicted with the aid of computer, and obioavail 1.1 1.1 and pre-caco-2 prediction models are used to screen the active ingredient group. Identify the target of all potential active ingredients, build the "active ingredient target" network by using the software of Cytoscape 3.6.1, analyze the topological properties of the network by using the plug-in of "network analyzer", and analyze the enrichment of KEGG pathway by using the online analysis tool David. Results 39 compounds identified in Polygonatum sibiricum, 18 of them have good ADME properties. Among these potential active ingredients, a total of 14 active ingredients and their corresponding 19 targets are closely related to the anti-tumor disease activity of Polygonatum sibiricum. Four key compounds, including baicalein, 3 ' - methoxydaidzein, isoliquiritigenin, (2R) - 7-hydroxy-2 - (4-hydroxyphenyl) - 4-phenylpropyldihydrofuran; and two key targets including prostaglandin G/H synthase 2 and Heat shock protein HSP 90 were obtained by constructing and analyzing the "active component-target" network. In addition, a total of 12 pathways related to antitumor disease were obtained when the KEGG pathway analysis was performed on the target. Conclusion Polygonatum sibiricum can exert its anti-tumor disease activity through the action mechanism of multiple components, multiple targets and multiple pathways.
