BACKGROUND: Mesona procumbens is consumed as a herbal drink and jelly-type dessert in Taiwan. The aim of this study was to determine the mechanism of anti-inflammatory activities of the aqueous extract of M. procumbens (AMP) using the gamma-carrageenin (Carr)-induced mouse paw oedema model. The fingerprint chromatogram of AMP was obtained by high-performance liquid chromatography (HPLC) analysis. To investigate the anti-inflammatory mechanism of AMP, the activities of catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) and the level of malondialdehyde (MDA) in paw oedema were monitored. Serum nitric oxide (NO), tumour necrosis factor-a (TNF-alpha) and interleukin-1 beta (IL-1 beta) were also evaluated. %26lt;br%26gt;RESULTS: The fingerprint chromatogram from HPLC indicated that AMP contained protocatechuic acid, chlorogenic acid, vanillic acid and caffeic acid. In the anti-inflammatory test, AMP decreased paw oedema after Carr administration and increased the CAT, SOD and GPx activities and decreased the MDA level in paw oedema at 5 h after Carr injection. AMP also affected the serum NO, TNF-alpha and IL-1 beta levels at 5 h after Carr injection. Western blotting revealed that AMP decreased the expression of Carr-induced inducible nitric oxide synthase (iNOS) and cyclooxygenase- 2 (COX-2). %26lt;br%26gt;CONCLUSION: Mesona procumbens has the potential to provide a therapeutic approach to inflammation-associated disorders.
