Abstract Ethnopharmacological relevance: Rhizoma Curcumae and Rhizoma Sparganii (RCRS), a celebrated traditional Chinese medicine drug pair, has been used to treat hysteromyoma (HY).Aim of the study: We aimed to identify the endogenous biomarkers of RCRS against HY.Materials and methods: HY rat model was established by injecting intramuscularly estradiol benzoate and progesterone injection from inner thigh in sequence. Body weight, uterus morphological indexes, immunohistochemistry (IHC) and hematoxylin and eosin (HE) staining experiments were used to evaluate the efficacy of RCRS (The rats were treated with RCRS extract, which was made by soxhlet reflux method. The rats were administrated intragastrically with 2 mL of RCRS extract). UPLC-Q-TOF-MS based metabonomics was adopted to analyze the serum and urine biomarkers from HY rats before and after RCRS treatment. Principle component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were utilized to identify differences of metabolic profiles in rats among the four groups.Results: 16 potential biomarkers from serum and 18 potential biomarkers from urine in both positive and negative mass spectrometry detection modes were identified, primarily related to Linoleic acid metabolism and Glyoxylate and dicarboxylate metabolism. RCRS drug pair has therapeutic effects on rats with HY via the regulation of multiple metabolic pathways.Conclusions: This study provides a useful method to get insight into the integrated metabonomic mechanism of RCRS drug pair on HY rats.
