4-O-Caffeoylquinic acid as an antioxidant marker for mulberry leaves rich in phenolic compounds.

Journal of food and drug analysis
Mulberry (Morus alba L.) leaves are widely used as herbal tea to prevent heat stroke. Potential chemical markers of the antioxidant properties and its correlation with harvesting times and leaf location were explored in this study. A 2,2-diphenyl-1-p...

Fast and easy extraction of antidepressants from whole blood using ionic liquids as extraction solvent.

Talanta
This study aims to prove that ionic liquids (ILs) can be used as extraction solvents in a liquid-liquid microextraction, coupled to LC-MS/MS, for the quantification of a large group of antidepressants in whole blood samples. The sample preparation pr...

Simultaneous determination of Vitamin A, 25-hydroxyl vitamin D α-tocopherol in small biological fluids by liquid chromatography-tandem mass spectrometry.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
A sensitive method for the simultaneous analysis of vitamin A (VA), 25-hydroxyl vitamin D (25-OH VD) and α-tocopherol (VE) in children plasma by liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed and validated. Sample prepar...

UPLC-MS/MS method for the simultaneous quantification of sofosbuvir, sofosbuvir metabolite (GS-331007) and daclatasvir in plasma of HIV/HCV co-infected patients.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
Direct-acting antiviral agents (DAAs) represent the major advance in hepatitis C virus (HCV) infection treatment leading to extremely high eradication rates in HCV mono- and HIV/HCV co-infected patients. In this scenery, availability of Therapeutic D...

Rapid and sensitive method for simultaneous determination of first-line anti-tuberculosis drugs in human plasma by HPLC-MS/MS: Application to therapeutic drug monitoring.

Tuberculosis (Edinburgh, Scotland)
First-line anti-tuberculosis drugs are playing vital roles for curbing rapid spread of tuberculosis. Multidrug therapies are commonly applied in clinical to achieve better treatment outcomes. However, drug resistance and adverse reactions come along ...

Determination of ractopamine and salbutamol in pig hair by liquid chromatography tandem mass spectrometry.

Journal of food and drug analysis
A liquid chromatography tandem mass spectrometric method was developed for the determination of two β-agonists (ractopamine and salbutamol) in pig hair samples. An isotope of ractopamine-d5 or salbutamol-d6 as an internal standard was used to carry o...

Hyperspectral Imaging and Support Vector Machine: A Powerful Combination to Differentiate Black Cohosh (Actaea racemosa) from Other Cohosh Species.

Planta medica
(black cohosh) has a history of traditional use in the treatment of general gynecological problems. However, the plant is known to be vulnerable to adulteration with other cohosh species. This study evaluated the use of shortwave infrared hyperspect...

Modified QuEChERS method for 24 plant growth regulators in grapes using LC-MS/MS.

Journal of food and drug analysis
A multiresidue analytical method was developed for grapes for the following 24 plant growth regulators: 1-naphthylacetamide, 2,3,5-triiodobenzoic acid, 2,4,5-T, 2-naphthoxyacetic acid, 3-indolylacetic acid, 4-(3-indolyl)-butyric acid, 4-chlorophenoxy...
