胶束电动毛细管色谱安培检测中药马齿苋中多巴胺和去甲肾上腺素 总被引:2,自引:0,他引:2
建立了胶束电动毛细管色谱结合电化学安培检测同时分析中药马齿苋中多巴胺和去甲肾上腺素的方法。考察了缓冲液的浓度、pH值、十二烷基硫酸钠(SDS)浓度以及工作电极电势对分离检测的影响。在优化的条件下,多巴胺和去甲肾上腺素在1.0×10-6~5 0×10-4mol/L范围内有良好线性,浓度检测限(S/N=3)分别为8 7×10-7mol/L和4 2×10-7mol/L,质量检测限分别为1 45fmol和0 41fmol。该方法组分定性可靠,不需要衍生处理,选择性好。将该法应用于中药马齿苋样品的分析,获得了较好的结果。 相似文献

Abstract This article describes validated high-performance liquid chromatographic (HPLC) and high-performance thin-layer chromatographic (HPTLC) methods for simultaneous estimation of alprazolam (ALZ) and sertraline (SER) in pure powder and tablet formulation. The HPLC separation was achieved on a Nucleosil C18 column (150 mm long, 4.6 mm i.d., and 5-µm particle size) using acetonitrile and phosphate buffer (50 + 50 v/v), pH 5.5, as the mobile phase at a flow rate of 1.0 mL/min at ambient temperature. The HPTLC separation was achieved on an aluminum-backed layer of silica gel 60 F254 using acetone/toluene/ammonia (6.0:3.0:1.0, v/v/v) as the mobile phase. Quantification with the HPLC method was achieved with ultraviolet (UV) detection at 230 nm over the concentration range 3–18 µg/mL for both drugs with mean recovery of 101.86 ± 0.21 and 100.57 ± 0.31% for ALZ and SER, respectively. Quantification in HPTLC was achieved with UV detection at 230 nm over the concentration range of 400–1400 ng/spot for both drugs with mean recoveries of 101.32 ± 0.15 and 100.38 ± 0.51% for ALZ and SER, respectively. These methods are rapid, simple, precise, sensitive, and are applicable for the simultaneous determination of ALZ and SER in pure powder and formulations. 相似文献

Ion-Pair Reversed-Phase Thin-Layer Chromatography and High-Performance Liquid Chromatography of Benzoic Acids 总被引:1,自引:0,他引:1
The separation of benzoic acids by ion-pair reversed-phase thin-layer chromatography and high-performance liquid chromatography was studied. In the optimization of separation conditions, the effect of the nature and concentration of the organic solvent, acidity of the mobile phase, concentration of salts of quaternary ammonium bases, and the length of their hydrocarbon radical on the retention of benzoic acids was studied. Conditions of the separation of a mixture of benzoic, hydroxybenzoic, aminobenzoic, and nitrobenzoic acids on Silufol plates impregnated with cetyltrimethylammonium bromide were selected; the mobile phase was isopropanol–ammonium acetate buffer solution with pH 5–dodecyltrimethylammonium bromide. 相似文献
