| Abstract: | A new asparagine Schiff-base and its complexes with La、Nd、Er、Dy are synthesized and characterized with elemental anslysis,IR spectra,UV spectra and mole conductivity and their scavenging effect on O-2 are investigated through EPR spectra.The results show that their O-2scavenging effect on O-2 is significant.It is proved that compounds synthesized in this paper show good physiological activities. |
