TAILIEUCHUNG - Investigating the anti inflammatory activity of an ethanolic extract from artocarpus tonkinensis leaves using a collagen antibody induced arthritic mouse model
This study was contrived for evaluating the in vitro and in vivo anti-inflammatory effects of an aqueous ethanolic leaf extract of the Vietnamese Artocarpustonkinensis A.

Chev. exGagnep. usinglipopolysaccharide-stimulated RAW macrophages and a collagen antibody-induced arthritic mouse model as well. The obtained results here demonstrate that the 70 % ethanolic leaf extract of A. tonkinensis(AT2), traditionally used in Vietnamese folk medicine for treating arthritic symptoms, has beneficial effects on pro-inflammatory cytokine inhibition and in an experimental arthritic mouse RAW macrophages treated with AT2 showed a significant decrease in the production of IL-6 and TNF at concentrations of , 25 and 50 µg/mL (P < ), indicating its potential anti-inflammatory properties. The treatment of CAIA mice with AT2 also led to diminish the .
