Abstract:
This study aims to establish a quantitative method of 4 aristolochic acids-DNA adducts in mice kidney and liver based on high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) for monitoring the content changes of aristolochic acids-DNA adducts. A Shiseido Capcellpak AQ C_(18) column(3 mm×100 mm, 3 μm) was used, with a mixture of 0.2% acetic acid-5 mmol·L~(-1) ammonium acetate as the aqueous phase and methanol as the organic phase for gradient elution. The multiple reaction monitoring(MRM) scanning method under positive mode by electrospray ionization(ESI) was performed for the detection of the aristolochic acids-DNA adducts which formed by combining aristolochic acid Ⅰ/Ⅱ with deoxyadenosine, deoxyguanosine, and deoxycytidine, respectively. Balb/c mice were given Guanmutong extract by gavage, and the relative content of aristolochic acids-DNA adducts in liver and kidney samples were analyzed within 60 days. It was found that the concentration of 4 aristolochic acids-DNA adducts in the kidney was significantly higher than that in the liver, and there were about 15.87 adducts in per 1×10~6 normal deoxynucleosides, which was 4.5-7.5 times than that of the liver. What's more, some adducts can still be detected on the 30 th day after administration. The concentration of the adducts in the liver was highest on the first day after administration, and a second peak appeared during the 7 th to 14 th days. The results indicated that aristolochic acids-DNA adducts are difficult to eliminate in vivo, and it is of great significance to study the mechanism of liver and kidney injury of aristolochic acid.
