Abstract

Huzhentongfeng (HZTF) is a compound extract developed by Guangzhou (Jinan) Biomedical Research and Development Center for treating gout. To investigate the antioxidative activity and anti-inflammatory activity of HZTF, the scavenging activity of hydroxyl radical, ferrous ions chelating ability and ferric reducing antioxidant power (FRAP) were used as indicators to evaluate the antioxidant activity and the lipopolysaccharide(LPS)-induced RAW264.7 macrophages were used to assess its anti-inflammatory activity. The results showed that HZTF had certain antioxidant activity, the IC50 values of HZTF in hydroxyl radical scavenging activity and ferrous ions chelating ability are 163.83 ± 10.49 and 899.72 ± 20.98 μg/mL, respectively and the FRAP value of HZTF are 8.97 ± 0.63 mol FeSO4/g. Moreover, HZTF significantly reduced IL-1β, IL-6, TNF-α, iNOS expression and NO production in LPS-induced RAW264.7 macrophages (P < 0.05), which demonstrate that HZTF have good potential to be developed as antioxidant or anti-inflammatory medicines.
