| Abstract: | Chemiluminescence reaction of potassium permanganate-kaempferol-perhydrol system was investigated with flow injection technique.The effect of factors on chemiluminescence intensity was tested,and a new method for determination of trace kaempferol was established with flow injection chemiluminescence.The linear range for kaempferol was between 1.0×10-7g·mL-1 and 1.0×10-4g·mL-1 with the detection limitation of 1×10-10g·mL-1,and the relative standard deviation was 2.1% for kaempferol concentration of 1.0×10-6g·mL-1 for 11 repeated measurements.The method is applied to determine the content of kaempferol in radix tetrastigme with satisfactory results. |
