缺磷条件下玉米根系分泌有机酸的高效液相色谱测定方法研究
Determination of organic acids secreted by maize roots under phosphorus deficiency by high-performance liquid chromatography
A high-performance liquid chromatography (HPLC) method was established for the determination of organic acids secreted by maize roots under phosphorus-deficient conditions.By optimizing the chromatographic conditions,quantitative analysis of tartaric acid,citric acid,malic acid,succinic acid,and fumaric acid was achieved.The results showed good separation of the five organic acids,with linear correlation coefficients R2>0.999.The limits of detection (LOD) ranged from 0.01 to 0.90 μg/mL,and the limits of quantification (LOQ) ranged from 0.15 to 5.00 μg/mL.The relative standard deviations (RSD) were 2.48%-3.77%,and the recoveries ranged from 89.0% to 118.7%.The method is simple,sensitive,and reproducible,making it suitable for the batch quantitative analysis of organic acids secreted by maize roots under phosphorus-deficient conditions.
