The active ingredients analysis of Herba Lysimachiae treating osteoarthritis based on the LC–MS/MS technology and public bioinformatics platforms

다국어 초록 (Multilingual Abstract)

Herba Lysimachiae inhibits synovial damage in osteoarthritis via regulating two bio labels (integrin alpha 2b/beta 3). However, the relevant active ingredients are still unknown. Here, the active ingredients of herbal medicines were analyzed based on the liquid chromatography–tandem mass spectrometry technology and public bioinformatics platforms. The liquid chromatography–tandem mass spectrometry technology was used for compound analysis, and public databases (PubChem BioAssay and STRING) were applied to establish the links between herbal compounds and both bio labels, and identify which herbal compounds may regulate these bio labels. Subsequently, the osteoarthritis model was used to confirm the results. Totally, ninety compounds in Herba Lysimachiae were identified based on the liquid chromatography–tandem mass spectrometry technology. Bioinformatics analysis showed that five compounds (myricetin, fisetin, esculetin, 7‐hydroxycoumarin‐4‐acetic acid, and caffeic acid) may synergistically regulate bio labels through 11 targets, which may be the active ingredients of Herba Lysimachiae for osteoarthritis treatment. In the verification experiments, five compounds markedly suppressed the overexpression of bio labels in the synovium of the osteoarthritis model. In conclusion, the present study effectively and rapidly analyzed the active ingredients of Herba Lysimachiae for osteoarthritis treatment.
