The flowers of Tripetaleia paniculata were extracted with methanol and the extract was treated (Chart 1). Compounds detected are higher aliphatic saturated hydrocarbons, ester, alcohols, epifriedelinol, β-sitosterol, ursolic acid, oleanolic acid, maslinic acid, β-sitosteryl β-D-glucoside, quercetin, avicularin, hyperoside, 6-hydroxy-7-methoxycoumarin, monotropein, arabinose, xylose, glucose, sucrose, and toxic diterpene, rhodojaponin-III. From the wood extract of the same plant were detected hydrocarbons, esters, taraxerol, taraxeryl acetate, friedelin, epifriedelinol, β-sitosterol, ursolic acid, oleanolic acid, acetyloleanolic acid, 3-O-(p-hydroxy-trans-cinnamoyl)-ursolic acid, β-sitosteryl β-D-glucoside, monotropein, monotropein methyl ester, lyonisidem, and 2, 6-dimethoxy-p-benzoquinone.
