Abstract:
Objective To investigate the anti-inflammatory effects and mechanism of durian peel extracts (DPE). Methods The in vivo anti-inflammation effects of DPE were examined by carrageenin-induced mice paw edema test and allergic contact dermatitis test induced by 2, 4-DNFB. And the in vitro anti-inflammation effects of DPE were evaluated with methyl thiazolyl tetrazolium ( MTT) assay in RAW 264.7 cell model of inflammation induced by lipopolysaccharide (LPS). Results The results of animal experiments showed that DPE groups could markedly relieve mice paw edema induced by carrageenin ( P<0.01 or P<0.001 compared with blank group). DPE could effectively inhibit the allergic contact dermatitis induced by 2, 4-DNFB in mice, showing good dose-effect relationship. The results of in-vitro test showed that DPE at the given concentrations had no influence on RAW 264.7 cell proliferation. Tumor necrosis factor alpha ( TNF-α) , interleukin 6 ( IL-6) , interleukin 1 beta (IL-1β), nitric oxide (NO) and nuclear factor kappaB (NF-кВ ) were observably inhibited, and anti-inflammatory cytokine IL-10 was enhanced by 25 and 50 mg/L of DPE. Conclusion DPE exert potential anti-inflammation effect, and the mechanism might be related to its inhibition of NF-кВsignal pathway.
