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).
CONCLUSIONS
All compounds are isolated from L. bulbifera and among compounds 3 and 4 are reported as natural products for the first time.
