Previously Undescribed Esters and an Alkaloid From Trollius chinensis With Anti-Inflammatory and Cytotoxic Activities. [PDF]
Chem BiodiversTen new compounds (9 esters, 1 alkaloid) were isolated from the flowers of Trollius chinensis Bunge, and all isolated compounds were evaluated in vitro for cytotoxicity against HeLa, HepG2, HCT 116 cells, and NO inhibition in RAW 264.7 macrophages, enriching structural diversity and providing a chemical basis for further study. . ABSTRACT In this study,

Determination of chlorinated solvents in industrial water and wastewater by DAI–GC–ECD [PDF]
Analytical and Bioanalytical Chemistry, 2011 A very simple and quick analytical method, based on direct aqueous injection, for determination of halogenated solvents in refinery water and wastewater, is described. There is a need to determine halogenated solvents in refinery water streams, because they may originate from several processes. There is also a need to develop methods enabling VOX to be
