hydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction

hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

Determination of polyphenols with HPLC-sensitized chemiluminescence.

DETERMINATION OF AMOXYCYLLIN AND CLAVULANIC ACID IN PHARMACEUTICAL DOSAGE FORMS BY HPLC WITH AMPEROMETRIC DETECTION

A simple and sensitive high performance liquid chromatographic method with electrochemical detection is described for the quantitative determination of the amoxycillin and clavulanic acid in pharmaceutical dosage forms. Separation of sample components occurs on a reversed phase C18 column with a mobile phase consisting of methanol-water-phosphate buffer. For the amperometric detection, the pote...

Development of an Analytical Method for Catecholamines with HPLC−Chemiluminescence Detection and its Application

Catecholamines (norepinephrine (NE), epinephrine (E) and dopamine (DA)) play important roles as neurotransmitters or hormones, and are known to be metabolized by catechol−O−methyltransferase (COMT) and monoamine oxidase. As shown in Figure 1, catecholamines are metabolized into their respective 3−O− methyl metabolites (normetanephrine (NMN), metanephrine (MN) and 3−methoxytyramine (3−MT)) by CO...
