    Abstract:
    Standardization of processing methods for herbs is as important as authentication to maintain their quality and ensure their safe use. We had previously prepared a standardized and purified Salvia miltiorrhiza Bunge extract, PF2401-SF, and showed that it protects against liver injury in vivo, at a greater potency than an ethanol extract. PF2401-SF was enriched with tanshinone I (11.5%), tanshinone IIA (41.0%), and cryptotanshinone (19.1%). In this study, we investigated potential anti-inflammatory effects of PF2401-SF in vitro and in vivo. We demonstrated that PF2401-SF shows anti-inflammatory potency on lipopolysaccharide (LPS)-induced nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in RAW 264.7 cells. A mechanistic study indicated that PF2401-SF induced heme oxygenase (HO)-1 expression through extracellular signal-regulated kinases (ERK1/2) phosphorylation. Moreover, we also evaluated that PF2401-SF significantly reduced inflammation on carrageenan- or dextran-induced acute arthritis in rats. Our results suggest that PF2401-SF may be a potential candidate for the treatment of various inflammatory diseases.
