High-sensitivity direct analysis of aflatoxins in peanuts and cereal matrices by ultra-performance liquid chromatography with fluorescence detection involving a large volume flow cell.
Journal of environmental science and health. Part. B, Pesticides, food contaminants, and agricultural wastes
Dec 26, 2017
This paper reports a sensitive and cost effective method of analysis for aflatoxins B1, B2, G1 and G2. The sample preparation method was primarily optimised in peanuts, followed by its validation in a range of peanut-processed products and cereal (ri...
Simultaneous quantitative determination of bioactive terpene indole alkaloids in ethanolic extracts of Catharanthus roseus (L.) G. Don by ultra high performance liquid chromatography-tandem mass spectrometry.
Journal of pharmaceutical and biomedical analysis
Dec 25, 2017
A rapid, sensitive and reproducible method using ultra-high-performance liquid chromatography coupled with electrospray ionization hybrid triple quadrupole-linear ion trap mass spectrometry (UHPLC-ESI-QqQ-MS/MS) in multiple reaction monitoring (MRM) ...
Determination of soyasaponins in Fagioli di Sarconi beans (Phaseolus vulgaris L.) by LC-ESI-FTICR-MS and evaluation of their hypoglycemic activity.
Analytical and bioanalytical chemistry
Dec 21, 2017
Soyasaponins are oleanene-type triterpenoid saponins, naturally occurring in many edible plants that have attracted a great deal of attention for their role in preventing chronic diseases. The aim of this study was to establish the distribution and t...
Extraction optimization, purification and characterization of polysaccharides from the seed coat of black soybean.
PloS one
Dec 21, 2017
In this study, the extraction of water-soluble polysaccharides from the seed coat of black soybean (BSCP) was investigated and optimized. A response surface methodology based on a Box-Behnken design (BBD) was used to optimize the extraction condition...
Quantitative Determination of Δ9-THC, CBG, CBD, Their Acid Precursors and Five Other Neutral Cannabinoids by UHPLC-UV-MS.
Planta medica
Dec 20, 2017
Cannabinoids are a group of terpenophenolic compounds in the medicinal plant (Cannabaceae family). Cannabigerolic acid, Δ-tetrahydrocannabinolic acid A, cannabidiolic acid, Δ-tetrahydrocannabinol, cannabigerol, cannabidiol, cannabichromene, and tetr...
Identification and characterization of the structure-activity relationships involved in UGT1A1 inhibition by anthraquinone and dianthrone constituents of Polygonum multiflorum.
Scientific reports
Dec 20, 2017
The adverse effects of Polygonum (P.) multiflorum, including abnormal bilirubin metabolism, are a serious public health issue. As uridine diphosphate (UDP)-glucuronosyltransferase 1A1 (UGT1A1) is the only enzyme responsible for bilirubin metabolism, ...
4-O-Caffeoylquinic acid as an antioxidant marker for mulberry leaves rich in phenolic compounds.
Journal of food and drug analysis
Dec 19, 2017
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
Dec 16, 2017
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
Dec 15, 2017
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...
