From a MeOH extract of powdered roots of Wikstroemia indica, we isolated a new guaian-type sesquiterpene (1) and two known guaian-type sesquiterpenes [oleodaphnal (2), 1alpha,7alpha,10alphaH-guaia-4,11-dien-3-one (3)], together with twelve known compounds: (+)-arctigenin, (+)-matairesinol, (+)-trachelogenin, (+)-nortrachelogenin, (+)-hinokinin, (+)-kusunokinin, 7-methoxycoumarin, 7-hydroxycoumarin (umbelliferone), daphnogitin, daphnoretin, salicifoliol, and (-)-pinoresinol. The structure of compound 1 was determined to be 4,10,11-guaiatrien-3-one-14-oic acid, by the analyses of spectral data.
