Isolation and determination of three new compounds from the leaves of Ailanthus triphysa (Dennst.) Alston with their anti-inflammatory activity. Ten tirucallane triterpenes (1-10) including four undescribed compounds, ailantriphysas A-D (1-4), were isolated from the leaves of Ailanthus triphysa (Dennst.) Alston. Their structures were elucidated using IR, HR-ESI-MS, 1D- and 2D-NMR spectra. Compound 1 inhibited lipopolysaccharide(LPS)-induced nitric oxide production in RAW 264.7 cells with an IC value of 8.1±μM. Additionally, compound 1 also displayed significant inhibitory effects on the secretion of IL-6 and TNF-α at tested concentrations of 4, 8, and 16 μM.
