1The Key Laboratory of Chemistry for Natural Products of Guizhou Province and Chinese Academy of Sciences, Guiyang 550002, China.
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.
