OBJECTIVE: To study the chemical constituents of Laportea bulbifera. METHODS: 70% EtOH was used for constituent extraction, silica gel column chromatography for constituent seperation, physical and chemical properties together with spectroscopic methods for chemical structure identification. RESULTS: six compounds were obtained from root of L. bulbifera. Their chemical structures were elucidated as p3-sitosterol(1) , P-daucosterol (2), 2,2'-oxy-bis(1-phenylethanol (3), 1-(2-phenylcarbonyloxy acetyl) benzene (4) , methyl linoleate(5),1,4-diphenyl-1,4-butanedione(6). CONCLUSION: All compounds are isolated from L. bulbifera and among compounds 3 and 4 are reported as natural products for the first time.
