One possible explana- tion for this is the relatively high amount of application solvent dichloromethane (100 mL/kg soil) that was used in this experiment. Dichloromethane has a measured log Koa of 2.27 and has been reported to reduce enzymatic activity in soil at concentrations as low as ...
Chlorinated aliphatic hydrocarbons (CAH) such as dichloromethane, tetrachloroethene, tri-chloroethane, tricholoroethene, etc. have been widely used as degreasers and solvents in various industries for more than 50 years. CAHs in general are harmful to human and ecological health. They can cause, ...
Once it had reacted, the reaction medium was concentrated then taken up in dichloromethane. The organic phase, in accordance with the nature of the groups R1, R3, R4, R5 and R6, was washed with a 1M HCl aqueous solution, a 1M NaHCO3 aqueous solution and with water. After drying on ...
4.1. Antioxidant Activity It is well known that an endogenous stimuli, like cellular metabolism, and exogenous agents like UV, toxins, and drugs, among others, generate reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), the superoxide anion (), and hydroxyl ion (HO−), as w...
Preliminary analysis of solvent subfractions of graviola powder reveals that the anti-cancer activities are concentrated mainly in the acetogenin- and alkaloid-rich dichloromethane (DCM) fraction. 2. Results 2.1. GLSE Inhibits Cell Proliferation, Viability and Clonogenicity of UW-BCC1 and A431 ...
