New Guaiane Sesquiterpenes from the Fruits of Torilis japonica.
Three new guaiane type sesquiterpenes were isolated from the methanolic extract of the fruits of Torilis japonica together with a known compound, torilin (1). Their structures were established as 11-acetoxy-8-isobutyryl-4-guaien-3-one (2), 11-acetoxy-8-methacrylyl-4-guaien-3-one (3), and 11-acetoxy-8-propionyl-4-guaien-3-one (4) by spectroscopic methods. These compounds inhibited lipopolysaccharide (LPS)-induced nitric oxide production in murine macrophages RAW 264.7 cells.
