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...
Validation of a HPLC Method for the Determination of Benzoic Acid and Sorbic Acid in Noodles
A simple, sensitive and specific HPLC method was validated for the simultaneous determination of benzoic acid and sorbic acid in noodles. Sample preparation involved the extraction with methanol and water (60:40, v/v). The separation was achieved on a GerminiC18 modified silica column (50 mm x 4.6 mm i.d., 5 μm particle diameter). The mobile phase consisted of 0.05 M ammonium acetate (pH 4.4) a...
متن کاملDetermination of tramadol, metamizole, ropivacaine, and bupivacaine in analgesic mixture samples by HPLC with DAD detection.
A high-performance liquid chromatography-diode array detection method was developed and validated to simultaneously determine tramadol (TMD), metamizole (MTZ), ropivacaine (RPV), and bupivacaine (BPV) in the presence of 4-methylaminoantypirine (4-MAA), the metabolite of MTZ, in analgesic mixtures samples used in Patient Controlled Analgesia (PCA). Chromatographic separation is achieved with a C...
متن کاملDetermination of 10-hydoxy -2-decenoic acid in pure Iranian royal jelly by HPLC method
Royal jelly (RJ) is generally regarded as the major reason of the significant morphological and functional differences between queen and worker bees. The unique and chemically most interesting feature of RJ is its fatty acids. RJ fatty acids are short-chained, 8-10 carbon free acids that are usually either hydroxy fatty acids or dicarboxylic acids. The major fatty acid in RJ is 10-hydroxy-2-dec...
