Comparison of anti-inflammatory effects of Lonicerae Japonicae Flos and Lonicerae Flos based on network pharmacology

Objective: In Chinese herbal medicine (CHM) history, Lonicerae Japonicae Flos and Lonicerae Flos were used clinically as one drug, but now they are admitted as two herbal medicines in Chinese Pharmacopoeia (2010 edition). This study used network pharmacology to investigate whether the two can be used interchangeably for the treatment of inflammatory diseases in TCM clinical practice. Methods: Lonicerae Japonicae Flos and Lonicerae Flos were compared in the inflammation mechanism including core targets, Gene Ontology (GO), pathway and principle chemical components by the method of network pharmacology. Results: Lonicerae Japonicae Flos and Lonicerae Flos shared in six targets accounting for 66.7% of the entire core targets and more than half of the GO terms and pathways are similar. Organic acids are dominent compounds responsible for anti-inflammatory effects. Three of the compounds that bind to core targets including luteolin, quercetin and kaempferol, are shared in both herbs. Conclusion: Due to high similarity between Lonicerae Japonicae Flos and Lonicerae Flos, we believe that they can be used interchangeably for the inflammation in clinical treatment.
