In this work we investigated the chemical constituents of water extract of the leaves of Cyclocarya paliurus. Two new megastigmane glycosides (3 and 8), three aliphatic alcohol glycosides (9-11), and two aromatic glycosides (12 and 13), along with fourteen known compounds were isolated, and their in vitro inhibitory activity against α-glucosidase was evaluated. Compounds 13 and 15-18 displayed inhibitory activity with IC values varying from 27.05 to 96.58 μM, and the structure-activity relationship among isolated compounds was discussed.

The high salinity and organic content in oil and gas wastewaters can cause ion suppression during liquid chromatography mass spectrometry (LC/MS) analysis, diminishing the sensitivity and accuracy of measurements in available methods. This suppression is severe for low molecular weight organic compounds such as ethanolamines (, monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), -methyldiethanolamine (MDEA), and ,-ethyldiethanolamine (EDEA)). Here, we deployed solid phase extraction (SPE), mixed-mode LC, triple quadrupole MS with positive electrospray ionization (ESI), and a suite of stable isotope standards (, one per target compound) to correct for ion suppression by salts and organic matter, SPE losses, and instrument variability.

Background: Salinity stress is a significant challenge in agriculture, particularly in regions where soil salinity is increasing due to factors such as irrigation practices and climate change. This stress adversely affects plant growth, development, and yield, posing a threat to the cultivation of economically important plants like . This study aims to evaluate the effectiveness by proactively applying indole-3-butyric acid (IBA) to cuttings as a practical and efficient method for mitigating the adverse effects of salinity stress.

Using high-level quantum chemical calculations, we predicted a strong O-H⋯C interaction between the apical carbon atoms of pyramidane and its derivatives and water molecules. Analysis of calculated electrostatic potential maps showed that there are areas of strong negative potential above apical carbon atoms in all studied structures. The results of quantum chemical calculations showed that the O-H⋯C interaction between the hydrogen atom of water and the apical carbon atom of pyramidane derivatives with four -CH substituents is unexpectedly strong, Δ = -7.
