BACKGROUND: Poppy Active Pharmaceutical Ingredients (APIs) are mainly used in the production of antitussives, analgesics, and other preparations. The alkaloid components play a major role, but the use of some alkaloids can cause dependence and toxic ...
The use of HPTLC fingerprinting for the analysis of traditional Chinese medicines (TCMs) usually involves several image-processing steps. However, these image-processing steps are time consuming. We describe a new approach that applies artificial n...
This work describes the development, validation, and application of two simple, accurate, and reliable methods for the determination of ursodeoxycholic acid (UDCA) in bulk powder and in pharmaceutical dosage forms. The carboxylic acid group in UDCA w...
Analysis of pesticide residues in irrigated rice grains is important for food security. In this study, we analyzed accelerated solvent extraction (ASE) conditions for the extraction of thiamethoxam and chlorantraniliprole insecticides from rice hulls...
Two accurate and sensitive methods were developed and validated for the simultaneous determination of amlodipine (AML), valsartan (VAL), and hydrochlorothiazide (HCT) in their ternary mixture. The first method is a novel simple algorithm capable of e...
Niuhuang Jiangya (NHJY) pill is one of the well-known Chinese patent medicines in China used in the treatment of high blood pressure. The primary purpose of this study was to establish and validate a method using HPLC with tandem MS for the quality e...
Accurate and precise TLC-densitometric and HPLC-diode-array detector (DAD) methods have been developed and validated to resolve two binary mixtures containing pyridoxine hydrochloride (PYH) with either cyclizine hydrochloride (CYH) or meclizine hydro...
A new, simple, efficient, and environmentally friendly ionic liquid dispersive liquid–liquid microextractionmethod was developed for the determination of irinotecan, an anticancer drug, in water and urine samples using UV-Vis spectrophotom...
Stability-indicating LC methods using a UV detector and a charged aerosol detector (CAD) simultaneously were validated for the assessment of alogliptin (ALG) in tablets. The analysis was performed on a C8 column (250 × 4.6 mm, 5 μm) at a flow of 0.8 ...
Sensitive detection of heavy metal ions in water is of great importance considering the effects that heavy metals have on public health. A developed fluidized bed enrichment technique was used to concentrate and detect low concentrations of Cu2+, Co2...
