Journal ArticleDOI
Simultaneous determination of illegal drug substances in dietary supplements for gout and osteoporosis using ultra-performance liquid chromatography and liquid chromatography-quadrupole-time-of-flight mass spectrometry
TL;DR: A rapid and accurate method to simultaneously measure 20 anti-gout and anti-osteoporosis drug substances using an ultra-high-performance liquid chromatography (UPLC) system equipped with a photodiode array (PDA) detector was developed and validated to fully meet internationally accepted standards.
Journal ArticleDOI
Development of a specific fragment pattern-based quadrupole-Orbitrap mass spectrometry method to screen adulterated products of phosphodiesterase-5 inhibitors and their analogues
TL;DR: A rapid and accurate method based on quadrupole-Orbitrap mass spectrometry was developed for simultaneously confirming and quantifying 85 PDE-5i and derived analogues present in illicit products for erectile dysfunction (ED).
Journal ArticleDOI
Isolation and characterisation of a novel sildenafil analogue adulterant, desmethylpiperazinyl propoxysildenafil, in a dietary supplement.
TL;DR: A new sildenafil analogue was detected during routine screening of dietary supplements suspected to be adulterated with an erectile dysfunction drug(s) using HPLC-DAD and was named as desmethylpiperazinyl propoxysildanafil.
Journal ArticleDOI
Simultaneous separation and determination of 20 potential adulterant antigout and antiosteoporosis pharmaceutical compounds in herbal food products using LC with electrospray ionization MS/MS and LC with quadrupole‐time‐of‐flight MS
TL;DR: By the proposed method, the presence of dexamethasone was determined in seized herbal food products at concentrations which ranged from 126 to 215 μg/g.
Journal ArticleDOI
Detection of Illegal Abortion-Induced Drugs Using Rapid and Simultaneous Method for the Determination of Abortion-Induced Compounds by LC–MS/MS
TL;DR: In this paper, a rapid and simultaneous liquid chromatography-tandem mass spectrometry method for detecting abortion-inducing drugs in counterfeit medicines was developed, which was used for validating the method using tablet-, powder-and capsule-type matrix-blank samples.
