Studies have shown that women's menopause caused by permanent cessation of ovarian function is closely related to lipid metabolism disorders. Er-xian Decoction has been used in the clinical treatment for gynecological diseases and has a good effect on diseases related to reduced sex hormone function. In this study, metabolomics was performed on bilateral ovariectomized model rats within 12 weeks after modeling to mimic the physiological state of menopausal women in different menopausal stages and Er-xian Decoction dosed model rats. The results of liver oil red O staining sections showed lipid metabolic disorder of bilateral ovariectomized model rats and the regulating effects of Er-xian Decoction. 46 potential biomarkers (6 steroid hormones, 3 sphingolipids, 11 phospholipids and 26 glycerides) in plasma and 32 potential biomarkers (1 steroid hormones, 20 phospholipids and 11 glycerides) in liver were obtained based on lipidomics analysis. Then, we analyzed the differential metabolic pathways and construct the lipid metabolism network significantly regulated by Er-xian Decoction. The results provided valuable information for in-depth understanding of the gradual changes on lipid metabolism disorders under menopausal conditions and the characteristics and mechanisms of compound Er-xian Decoction's regulatory effects. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00000918).
