Abstract

Ethnopharmacological relevance: Scutellaria baicalensis Georgi (Scutellariae Radix, SR) and Coptis chinensis Franch (Coptidis Rhizoma, CR) is a classic herbal pair used in many Traditional Chinese Medicine formulations in the treatment of hyperlipidemia (HLP). As effective ingredients of the drug pair, the effects and mechanisms of berberine and baicalin in the treatment of HLP in the form of components compatibility are still unclear.

Aim of the study: To explore the mechanism of the components compatibility of SR and CR in the treatment of HLP.

Materials and methods: The HLP model was established by a high-fat diet. Serum biochemical indexes were detected. Transcriptomics and metabolomics were detected. RT-PCR and Western Blot were used to analyze the effect of RA on the expression of the Cyp4a family during the treatment of HLP.

Results: Berberine-baicalin (RA) has a good effect in the treatment of HLP. RA can significantly reduce the body weight and liver weight of HLP, reduce the levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), and increase the level of high-density lipoprotein (HDL-C). Through transcriptomic analysis, RA significantly reversed the gene expression of Cyp4a10, Cyp4a12 b, Cyp4a31, and Cyp4a32 in cytochrome P450 family 4 subfamily a (Cyp4a) which related to fatty acid degradation in the liver of HLP mice. The results of fatty acid detection showed that RA could significantly regulate heptanoic acid, EPA, adrenic acid, DH-γ-linolenic acid, and DPA in the cecum of HLP mice. The Cyp4a family genes regulated by RA are closely related to a variety of fatty acids regulated by RA. RT-PCR confirmed that RA could regulate Cyp4a mRNA expression in HLP mice. WB also showed that RA can regulate the protein expression level of Cyp4a.

Conclusion: The components compatibility of SR and CR can effectively improve the blood lipid level of HLP mice, its mechanism may be related to regulating Cyp4a gene expression and affecting fatty acid degradation, regulating the level of fatty acid metabolism in the body.
