Method validation and simultaneous determination of retinol, retinyl palmitate, β-Carotene, α-Tocopherol and vitamin C in Rat serum treated with 7,12 dimethylbenz[a]anthracene and plantago major L. By high- Performance liquid chromatography using diode-array detection. https://doi.org/10.2174/1386207311316020008.1386-20731875-5402https://doi.org/10.2174/1386207311316020008https://hdl.handle.net/20.500.12402/2768A new and simple high-performance liquid chromatography method was developed and validated for the simultaneous determination of retinol, retinyl palmitate, β-carotene, α-tocopherol and vitamin C in rat serum treated with Plantago Major L. and 7,12 dimethylbenz[a]anthracene. High-performance liquid chromatography analysis was performed utilizing an Inertsil ODS3 reversed phase column with methanol-tetrahydrofuran-water as mobile phase under gradient conditions, at 1.5 mL min-1 flow rate and 25 °C. Diode-array detection was at 325, 450, 290 and 270 nm (retinol and retinyl palmitate), β-carotene, α-tocopherol and vitamin C, respectively and runnig time 18 min. The high-performance liquid chromatography assay and extraction procedure proposed are simple, rapid, sensitive and accurate. The method was then applied for the determination of retinol, retinyl palmitate, β-carotene, α-tocopherol and vitamin C in rat serum. Results of this study demonstrated that; at 60th day DMBA-treated group, there was a significant decrease in vitamin levels compared to the levels of control group. A significant increase was observed in vitamin levels of 7,12 dimethylbenz[a]anthracene+Plantago Major L.-treated group compared to the DMBA-treated group. Additionally, the results obtained in the study are found to be in agreement with data reported in the literature.eninfo:eu-repo/semantics/closedAccess12 Dimethylbenz[a]anthraceneHPLCPlantago Major L. 7SerumVitaminArticle162142149Q3Q2
