Investigation of antiinflammatory constituents of the stem and root barks of Ulmus davidiana var. japonica resulted in the isolation of three guaiane type sesquiterpenes, torilin, 1-hydroxytorilin, together with a new derivative, (1beta, 7beta, 8beta, 10beta)-1,8,11-trihydroxy-4-guaien-8-angeloyl-3-one named 1-hydroxytorilin A. All the three sesquiterpenes inhibited lipopolysaccharide-induced nitric oxide production in murine microglial BV2 cells.
