英文摘要A rhodamine nitroxide probe was designed to detect the hydroxyl radical (center dot OH), which presented high selectivity for center dot OH over other reactive oxygen species (ROS) and linear fluorescence response to center dot OH produced by Fenton reaction. The product was detected by HPLC-MS, indicating that the main product of the reaction was O-methylhydroxylamine and the product peak areas measured by HPLC-UV/vis and HPLC-FLD both enhanced proportionally with the increase of center dot OH concentration. The application of the probe in biological system was explored to trace the production of center dot OH in cells under oxidative stress condition induced by rotenone which can inhibit the mitochondria respiratory chain complex I and we found that appropriate rotenone may induce the normal human liver cells (L02) and human hepatoma cells (HepG2) to produce center dot OH at different degrees.
