    ABSTRACT

    Background: Radix Sanguisorbae has long been used to treat diarrhea, enteritis, duodenal ulcers, and internal hemorrhage. Objective: We investigated the in vitro anti‑inflammatory effects of Radix Sanguisorbae and performed quantitative analyses of three marker components, namely gallic acid, ellagic acid, and quercetin, using high‑performance liquid chromatography coupled with a photodiode array detector. Materials and Methods: The three marker components were separated using a reversed‑phase Gemini C18 analytical column maintained at 40°C by the gradient elution with two solvent systems. We examined the biological effects of the three marker compounds, gallic acid, ellagic acid, and quercetin, by determining their anti‑inflammatory activities in the murine macrophage cell line RAW 264.7. Results: All of the marker compounds exhibited inhibitory effects on prostaglandin E2 production in lipopolysaccharide (LPS)‑stimulated RAW 264.7 macrophages, with no cytotoxicity. Particularly, ellagic acid significantly inhibited production of the proinflammatory cytokines tumor necrosis factor alpha and interleukin‑6 in LPS‑treated RAW 264.7 cells. Conclusion: Our results suggest that ellagic acid is the most potent bioactive phytochemical component of radix Sanguisorbae in the treatment of inflammatory diseases.
