LC method for the analysis of acetylsalicylic acid, caffeine and codeine phosphate in pharmaceutical preparations

Quantitative HPLC analysis of mebeverine, mesalazine, sulphasalazine and dispersible aspirin stored in a Venalink monitored dosage system with co-prescribed medicines

“…It has been used for the quantitative determination of mebeverine HCl [11][12][13][14] and its stability in tablets [15], for the determination of 5-aminosalicylic acid (5-ASA) [16][17][18][19][20] and the stability of 5-ASA and its metabolites in plasma [21,22], for sulphasalazine [23,24] and for aspirin [25][26][27][28][29].…”

Anodic Determination of Acetylsalicylic Acid at a Mildly Oxidized Boron-Doped Diamond Electrode in Sodium Sulphate Medium

“…The CV measurements obtained corresponded to restricted potential limits ranged between 0 V and +1. 25 • C). Before starting each series of electrochemical measurements, the working electrode was carefully cleaned, degreased, and treated to remove fouling by polishing with alumina aqueous suspension, and finally thoroughly washed with double-distilled water.…”

“…The latter methods, used independently or coupled with various detection modes, were applied for ASA investigation in biological fluids, pharmaceutical preparations, and even waste waters [4,5,10,13,15,16]. The detection and determination of aspirin using the above-mentioned techniques have been achieved in both single [13,15,17,18] and multicomponent systems [10,[19][20][21][22][23][24][25][26][27][28][29].…”

Orthogonal array design for the optimization of hollow fiber protected liquid-phase microextraction of salicylates from environmental waters

“…With fluorescence detection, PAS could be determined as low as 50 ng mL −1 [35]. In the analysis of ASA in tablet, a simple solvent dissolution of tablet was performed prior to HPLC-DAD analysis with an LOD of 0.08 g mL −1 [36]. From these studies, we can see that there were few studies aiming at the determination of salicylates in environmental samples.…”
