They added a small amount of the fluorescent dye coumarin to the emitter material tris(8- hydroxy-quinoline) aluminum.
The method was applied to the calculation of the ring bond angles of furan, pyrrole, and coumarin. The calculated results are in good agreement with the experimental data.
Microwave-induced synthesis and antibacterial activity of thiosemicarbazone compounds based on coumarin-skeleton
Researchers have identified six coumarin derivatives that exert antispasmodic and vasodilatory effects.
Interestingly coumarin, the substance which gives newly mown hay its characteristic odor, is employed to impart a vanilla flavor to certain inferior tobacco products, and can be found as an ingredient in certain perfumes(2).
Biotransformation of natural coumarin by marine fungus Mucor and study on volatile composition
Cattle eating alfalfa corruption but had lost hemagglutination and bleeding to death, which may be due to the formation of a plant coumarin dicoumarol caused.
Study on coumarin extraction from Chimonan thus Salicifolius Hu by the surface-active agent
Synthesis of coumarin-3-carboxylic acid through sodium ethoxide catalyzed synthesis of coumarin -3-carboxylic acid ethyl ester, followed by saponification, acidolysis cyclization was studied.
Thus, 3 mol of Ethyl acetoacetate were treated with 2 mol of formaldehyde to yield 80% of I. Addn. of I at 0.01 g to a vanilla flavor compn. enhanced the flavour by making it more natural and imparting a coumarin-like, coconut-like aroma.
Objective To study the antitumor activity of otiose and coumarin in novobiocin.
Aglycone bacteriostasis of ash bark was superior to glycoside, fraxetin and aesculetin bacteriostasis were most powerful in 5 kinds of coumarin monomer.
preparation and evaluation of brain delivery property of lactoferrin conjugated self-assembled Polymer vesicles loaded 6-coumarin in vitro
