Individual and simultaneous determination of ephedrine and phenylephrine by use of kinetic methodology

Spectrophotometric Determination of Phenylephrine Hydrochloride by Coupling with Diazotized 2- Aminobenzothiazole

“…Different spectrophotometric methods have been applied for the determination of phenylephrine with different reagents such as 4-aminoantipyrine in presence of periodate or alkaline ferricyanide (Al-Abachi and Al-Ward, 2002;Hiskey and Levin, 1960) , nitrous acid in presence of copper ion (Yahia and Laila, 1976) , chloranil (Amer et al, 1982) , ninhydrin in sulphuric acid (Muszalska et al, 2000), periodate (Neil and Gelenn, 1971), methylbenzothiazoline-2-one hydrazone in presence of iron (Gala et al, 1994), haematoxylin (Ibrahim;Alaa,2007), 4-aminophenol (Sane and Narkar,1980), chloramine (Szekerer et al, 1973), N,N-dimethylaniline hydrochloride with potassium ferricyanide (Tatsuzawa and Shimoda, 1968), hydroxyl ammonium chloride with cupric ion (Deodhar and Mehta, 1978), sodium borate (Doulakas, 1975), fluorodinitrobenzene (Tammilehto, 1975), bromothymol blue (Matthew et al,1972), and diazotized p-nitroaniline (Auerbach, 1950;Kelly and Auerbach, 2006). Also, the ultraviolet (Fabrizo, 2006) and derivative spectrophotometry (Kazemipour and Ansari, 2005) methods have been used.…”

Chromatographic separation and analysis of chloropheniramine maleate, methscopolamine nitrate and phenylephrine hydrochloride in sustained release capsules

“…These methods include titrimetry [1,2], spectrophotometry [3,4], atomic absorption spectroscopy [5], electrophoresis [6], proton nuclear magnetic resonance (NMR) spectroscopy [7], high performance liquid chromatography (HPLC) [8][9][10], and gas chromatography (GC) [ 11 ]. PEH is analyzed by several methods such as titrimetry [ l 2,13 ], spectrophotometry [ 14,15], voltammetry [ 16], electrophoresis [ 17], thin layer chromatography (TLC) [18], HPLC [19,20] and GC [21]. The combination of CPM and PEH with or without other drugs has been analyzed simultaneously either in biological samples or in pharmaceutical dosage forms.…”

Potentiometric and Optical Measurements for the Determination of Ephedrine

“…Ephedrine has been determined using a wide variety of methods such as spectrophotometric (1)(2)(3)(4), polarographic (5), and potentiometric analysis (5)(6)(7). The application of ion-selective electrodes for ephedrine, for example, liquid ion exchangers, was introduced by Kuchkarev et al (8) and .…”
