Toona sinensis and its major bioactive compound gallic acid inhibit LPS-induced inflammation in nuclear factor-κB transgenic mice as evaluated by in vivo bioluminescence imaging

► Toona sinensis leaf extracts exhibits anti-inflammatory potential in vivo. ► NF-κB transgenic mice were subjected to bioluminescence imaging technique. ► Toona sinensis significantly suppressed LPS-induced NF-κB activation in vivo. ► Gallic acid also significantly down-regulated NF-κB activation in vivo.
