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.

Oxidants used in the ISCO technology usually require activation by activators to degrade contaminants. However, this study investigated degradation of 15 typical halogenated hydrocarbons by five common ISCO oxidants (PS, PMS, HO, KMnO, SPC) without activation in both pure water and real groundwater. Unactivated PS could degrade 14 halogenated hydrocarbons, excluding tetrachloromethane.

Methods: The primary components of PTQF were characterized using UHPLC-Q-TOF-MS/MS. The identified compounds subsequently employed network pharmacology to predict the signaling pathways associated with the inflammatory phase of POI.
