Abstract:
Objective Complex of oxymatrine(OMT)-carbenoxolone sodium(CS)was prepared,and the acute toxicity of the OMT-CS complex and their protective effects on injured liver induced by carbon tetrachloride(CCl_4)were also studied.Methods The OMT-CS complex was formed after preparing OMT and CS solutions individually then mixing them in ratio,the constant was detemined by UV-vis,the complex was characterized by powder X-ray diffraction,IR,and NMR.The sequence method was employed to test LD_50 of the complex by iv injection.The aspartate transaminase(AST)and alanine aminotransferase(ALT)in serum were measured in acute hepatic injuried models by CCl_4 proportionally im injected the complex in mice.Results The ratio of OMT and CS in the complex appeared to be 1∶1.The results of powder X-ray diffraction measurement indicated that a novel crystalline structure of complex was formed.The acute toxicities of LD_50 of the complexes in 1∶1,and 2∶1 were lower than that of both OMT and CS only.Compared with the model group by CCl_4,AST and ALT levels in serum were lower than that in the complex at 1∶1 and 2∶1 ratios.Conclusion The toxicity of the complex in different proportions on acute hepatic injuried mice by CCl_4 decreases obviously,compared with their precursor drugs.
