摘要
建立了氧化衍生化间接荧光光谱法测定哌嗪的方法。氢过氧单硫酸氢钾(Oxone®)被提出作为Periciazine的衍生化剂，生成强荧光Periciazine亚砜。用Oxone®溶液在0.02 M盐酸溶液中(λex = 364 nm;λem = 444 nm)。校正图在0.05 ~ 4.00µg mL -1浓度范围内呈线性关系。定量限(10S)为0.05µg mL -1。定量测定药物制剂(Neuleptil®，10 mg胶囊和Neuleptil®，30 mL 4%口服(溶液)滴剂)中哌嗪的可能性显示RSD < 2.2% (δ < RSD)。
The Oxidative Derivatization Method For The Spectrofluorimetric Determination Of Periciazine In Pharmaceutical Preparations
The oxidative derivatization method for the indirect spectrofluorimetric determination of Periciazine has been presented. Potassium hydrogenperoxymonosulfate (Oxone ®) is proposed as a derivatizing agent for Periciazine, yielding the strongly fluorescent Periciazine sulfoxide. A highly sensitive, simple and rapid method for determination of the Periciazine by fluorescence of its oxidation product with Oxone ® solution in 0.02 M hydrochloric acid solution (λex = 364 nm; λem = 444 nm) has been developed. The calibration plot is linear in concentration range of 0.05 – 4.00 µg mL -1 . LOQ (10S) is 0.05 µg mL -1 . The possibility of quantitative determination of Periciazine in pharmaceutical preparations (Neuleptil ®, 10 mg capsules and Neuleptil ®, a 30 mL 4 % oral (solution) drops) has been shown RSD < 2.2 % (δ < RSD).
