Background: Harrisonia perforata root is one of the five medicinal plants in Bencha-Loga-Wichien remedy used for the treatment of fever in Thai traditional medicine. The aim of this study was to investigate the anti-inflammatory effect and the action mechanism of the ethnolic extract from the root of H. perforata in vivo and in vitro. Methods: Male Wistar rats were divided into 6 groups and treated with either the ethanolic extract of H. perforata root at dose 5–400 mg/kg or indomethacin 5 mg/kg or vehicle. Rat paw volume was measured at 1, 2, 3, 4, 5 and 6 h after carrageenan injection. The in vitro mechanism of the antiinfammatory response was investigated through the measurement of mRNA expression of proinflammatory cytokines, TNF-α, IL-6 and IL-1β. Lipopolysaccharidestimulated macrophage, J774A.1 cell, were exposed to different concentration of H. perforata root extract (12.5–50 μg/ml). mRNA expression, TNF-α, IL-1β and IL-6, were determined by real-time RT-PCR. Cell viability was measured by rezasurin assay. Results: H. perforata root extract 50–400 mg/kg. significantly reduced the effect of acute inflammation in rat paw edema by 28.49%- 65.05% at 2 hour after carrageenan injection. Cell viability were not significantly altered by the presence of H. perforata extract 3.125–50 μg/ml. The maximum inhibitory effect for TNF-α, IL-1β and IL-6 were 49.83, 47.27 and 32.16% respectively. The concentration of the extract produced maximum effect were 50 μg/ml for both TNF-α and IL-1β but for IL-6, it was 12.5 μg/ml. Conclusion: The ethanolic extract from H. perforata root possesses anti-inflammatory effect. This may occur through suppression of proinflammatory cytokines.
