Simultaneous determination of synthetic colorants in yogurt by HPLC.

This article reports on a method to determine synthetic dyes in yogurts and milk drinks. Initially a method for extraction of artificial dyes was developed to pretreat samples in order to extract most of the artificial colorants. Then, the colorants were analyzed by HPLC-PAD using gradient elutions. The method was linear in the range of 0.5-25mgL(-1) colorants (0.9991<R(2)<0.9998), with LOD of ...

An Ion-pair Dispersive Liquid-Liquid Microextraction for Simultaneous Determination of Synthetic Dyes in Ice Cream Samples by HPLC

An efficient, sensitive and fast method was developed based on an ultrasound-assisted extraction followed by an ion-pair dispersive liquid-liquid microextraction (USAE-IP-DLLME) for the simultaneous determination of five commonly used synthetic sulfonate dyes (tartarazine, quinoline yellow, sunset yellow, azorubine, and brilliant blue) in ice cream samples using high performance liquid chromato...

Simultaneous Determination of Carbazoles in Water Samples by Cloud Point Extraction Coupled to HPLC

Cloud point extraction (CPE) as a rapid, simple and efficient method coupled with high performance liquid chromatography (HPLC) was used for sample preparation and subsequent determination of carbazole, trinitrocarbazole (TrNC) and tetra nitro carbazole (TNC) in water samples. Some effective parameters on extraction, such as volume of Triton X-100, extraction time, extraction temperature, ionic...

Simultaneous Determination of Dofetilide and Amlodipine in Plasma by HPLC

Dofetilide is a Class III antiarrhythmic drug useful in the management of atrial fibrillation but also known to prolong the QT interval on the ECG and to induce malignant ventricular tachyarrhythmias such as torsades de pointes (TDP). Drugs with calcium channel-blocking properties contribute to decrease the incidence of TDP. Amlodipine is a dihydropyridine calcium channel antagonist. Considerin...

Simultaneous determination of two biflavones in Biyanling Tablets by HPLC

Objective of the present study is to develop analytical methods for simultaneous determination of two major biflavones, amentoflavone and heveaflavone, in Biyanling Tablets, thereby providing methodological reference for quality control of anticancer drug Biyanling Tablets. Samples are chromatographed on Diamonsil C18 (4.6 mm × 250 mm, 5 μm) column with a mobile phase of acetonitrile (B)–0.5% a...
