    Asthma is an increasing global health problem, and novel strategies to prevent or ameliorate the condition are needed. The purpose of the present study was to evaluate the anti-inflammatory and anti-asthma effects of Adenophora triphylla var. japonica extracts. We investigated the molecular mechanism underlying the effects of 80% ethanol extracts (AE) of A. triphylla on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. AE treatment inhibited pro-inflammatory cytokines such as TNF-α and IL-6 as well as nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. In particular, NO and pro-inflammatory cytokine production was suppressed more effectively by aerial parts (AE-A) than roots (AE-R) of A. triphylla. Quantitative RTPCR assay showed that AE reduced mRNA levels of iNOS and COX-2. We also evaluated the anti-asthmatic effects of AE-A in an ovalbumin (OVA)-induced BALB/c mouse model. AE-A supplementation significantly reduced the amounts of airway eosinophils, IL-4 and IL-13 levels in BALF, and IgE levels in serum as compared with untreated, OVA-induced mice. These results suggest that AE-A can be considered as a therapeutic agent to potentially relieve asthma.
