本文确立了甜菜中甜安宁残留量高效液相色谱分析方法，甜菜样本用丙酮提取后，再萃取到二氯甲烷溶液中，经中性氧化铝柱净化，用Ｃ＿（１８）反相柱分离，流动相为甲醇／水（６０／４０）以紫外检测器在波长２３５ｎｍ下测定。甜菜根、植株、土壤的方法回收率范围为９０．８～１１７．９％，最小检出量均为２ｎｇ，检出极限，根、土壤皆为０．０１ｍｇ／ｋｇ，植株为０．０５ｍｇ／ｋｇ。 In this paper, a method was established for the determination of sweet and peaceful residues in sugar beet by high performance liquid chromatography (HPLC). The sugar beet samples were extracted with acetone and then extracted into methylene chloride solution. The samples were purified by neutral alumina column and separated by C 18 column. The mobile phase was methanol / water (60/40) with a UV detector at a wavelength of 235 nm. The recoveries ranged from 90.8% to 117.9% for beetroots, plants and soils with a minimum detection limit of 2ng. The limits of detection were 0.01 mg / kg in roots and soils, 0.05 mg / kg.
