ABSTRACT
To study the potential effect of Dioscorea nipponica(DN) in intervening peripheral system of rats based on metabolomic analysis. The identification of the potential intervention targets of DN in peripheral system may facilitate its safe application and therapeutic potential exploitation. Totally 20 male SD rats were randomly divided into the blank group and the DN-treated groups, with 10 rates in each group. The DN-treated group was orally administrated with DN extracts once a day for 5 days, with the dose of 80 mg x kg(-1) (equivalent to 15 g crude drug in human), and the blank group was given equal volume of saline once a day for 5 days. Heart, liver, spleen, lung, and kidney tissues and serum samples were collected from each rat 24 h later after the last administration. The ultra-performance liquid chromatography/quadrupole time-of-flight-mass spectrometry based metabolomics was used to investigate the effect of DN in intervening peripheral system of rats. After the treatment with DN, 5 modulated metabolites in heart tissue, 6 in liver tissue, 5 in spleen tissue, 3 in lung tissue, 5 in kidney tissue and 6 in serum sample were identified and considered as the potential intervention targets of DN. Effect of DN in regulating some endogenous metabolites was beneficial for protecting peripheral system, while that in other endogenous metabolites produced potential toxicity to peripheral system. The metabolomic analysis revealed the coexistence of protective and toxic effects of DN on peripheral system, which may be a practical guidance for its safe application and beneficial to the expansion of its application scope.
