INTRODUCTION

Sijunzi Decoction (SJZD) is a classical prescription in traditional Chinese medicine that enhances neuroimmune endocrine function to alleviate inflammatory aging, a key pathogenic mechanism underlying premature ovarian insufficiency (POI). However, the mechanism through which SJZD alleviates POI remains unknown. Hence, we aimed to identify the active components of SJZD and its mechanism of therapeutic action against POI.

METHODS

We identified compounds in SJZD using liquid chromatography-linear trap quadrupole- Orbitrap-mass spectrometry (LC-LTQ-Orbitrap-MS). Traditional Chinese Medicine Systems (TCMSP) and HERB databases were used to identify the ingredients and potential targets of SJZD. We analyzed Gene Ontology (GO) terms and enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways using RStudio and constructed a visual network using Cytoscape3.9.1.

RESULTS

We identified 98 compounds using LC-LTQ-Orbitrap-MS, among which 29 were bioactive. The screen outputted yielded 151 predicted targets of these compounds that were associated with POI. The results of the GO and KEGG analyses showed that these compounds play key roles in cell growth, division, migration, and survival signaling pathways. Therefore, phosphatidylinositol 3-kinase (PI3K)/AKT, mitogen-activated protein kinase (MAPK), and epidermal growth factor receptor (EGFR) pathways might be closely associated with the pharmacological effects of SJZD on the pathological processes of POI.

CONCLUSION

Our findings provide a scientific basis for rapidly analyzing bioactive compounds in SJZD and their pharmacological mechanisms.
