The Antioxidant and Anti-Inflammatory Properties of Merremia umbellata Extract.

ABSTRACT: Merremia umbellata Hallier f. (MU) has been used as an anti-inflammatory agent to treat burns and scales. However, the potential anti-inflammatory mechanisms of action of this plant have not been elucidated. This study aimed to assess the antioxidant and anti-inflammatory effects of the leaf and shoot of MU grown in Bangladesh. The MU extract exhibited antioxidant activities as demonstrated by DPPH and ABTS free-radical-scavenging activities and the total polyphenol and total flavonoid contents. MU extract significantly reduced the lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production in RAW264.7 macrophage. Accordingly, the gene levels of inducible NO synthase and cyclooxygenase-2 were suppressed. The MU extract alleviated the LPS-induced expression of TLR4, NF-κB, and i
