A phytochemical study of an ethanol-soluble extract from the root barks of Daphne tangutica Maxim., a traditional Tibetan herb medicine, led to the isolation of 30 compounds, including eight daphnane diterpenes, nine coumarines, six lignans, five phenylpropanoid derivatives, beta-sitosterol and p-hydroxy benzonate. Two compounds out of these isolates are new daphne diterpene analogs, and their structures were established as 1,2 alpha-dihydro-5 beta-hydroxy-6 alpha,7 alpha-epoxy-resiniferonol-14-benzonate, and 1,2 beta-dihydro-5 beta-hydroxy-6 alpha,7 alpha-epoxy-resiniferonol-14-benzonate, respectively, on the basis of spectroscopic methods. Additionally, this is the first time that 13 known compounds have been isolated and identified from this traditional Tibetan medicinal plant.
