[Studies on chemical constituents of Stellera chamejasma L].

Isolate and identify the bioactive compounds from the root of Stellera chamejasma. The compounds were extracted with solvents, isolated by column chromatography and identified by spectroscopic methods. Seven compounds were isolated and identified as umbelliferone(1); daphnoretin (2); 2,6-dimethoxyl p-benzoquinone(3); (-)-eudesmin(4); (+)-matairesinol(5); lirioresinol B(6) and daucosterol(7). Compounds 3, 4 and 5 were isolated from the plant for the first time.
