LC-ESI-MS/MS Alkaloidal Profiling and Biological Investigation of Cleistocactus winteri Stems
Cleistocactus winteri is a succulent plant of the Cactaceae family, commonly known as the golden rat tail. Many members of the Cactaceae family are the focus of chemical and biological studies as they contain bioactive compounds, well known for their health-related properties. We aimed to investigate Cleistocactus winteri stems both phytochemically and biologicallyfor the firs...

متن کاملHigh-Sensitivity Micro LC-MS/MS Assay for Serum Estradiol without Derivatization
Background: There are considerable demands to accurately measure estradiol (E2) at low concentrations (<20 pg/mL) in postmenopausal women, men, pediatric patients, and patients receiving breast cancer treatment. Most current high-sensitivity LC-MS/MS E2 methods require large sample volumes and involve complex sample preparations with dansyl chloride derivatization. Our study aims to develop a h...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Complementary Use of LC-ICP-MS and LC-ESI-Q-TOF-MS for Selenium Speciation.
We demonstrated the complementary use of inductively coupled plasma-mass spectrometry (ICP-MS) and electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-Q-TOF-MS) for the analysis of Se-containing compounds, such as selenate, selenomethionine (SeMet), and trimethylselenonium ion (TMSe), found in biological samples. The sensitivity of ESI-Q-TOF-MS for Se-containing compounds w...
