In current our study; we report the synthesis of the poly(ethyl methacrylate) coumarin
end grouped having hydroxyl (CEMA) by ATRP method.
A new benzofuran derivative glycoside and a new coumarin
glycoside from roots of Heracleum dissectum Ledeb.
After the execution period, the following variables were analyzed: height of the aerial part (cm), leaf area ([cm.sup.2]), dry mass of leaves and branches (g), total dry mass (g), and coumarin
content of the apical, middle, and basal segments of the plant tissue (mg [g.sup.-1]).
We demonstrate that after oral ingestion, MK-7 is more effective in both catalyzing osteocalcin carboxylation in bone and counteracting coumarin
anticoagulants in the liver.
Calculations of water solubility (LogS) show that coumarin-5 has the lowest LogS value (less water soluble), while chalepin coumarin
has the highest value, in accordance with logP calculations.
The flow rate was 0.6 mL/min, injection volume 50 [micro]L and the wavelength were 270 for gallic acid, 278 nm for coumarin
, 327 nm for chlorogenic acid and caffeic acid, and 365 nm for quercetin, quercitrin, kaempferol and rutin.
and its derivatives have been known for a long time, yet their vital role in plant and animal systems has not been thoroughly analyzed.
Herein, we report a highly sensitive fluorogenic Cys probe (1) by installing the recognition moiety of 2,4-dinitrobenzenesulfonyl ester (DNBS) onto a coumarin
We used two standard fluorophores: Erythrosin B and Coumarin
(2H-1-benzopyran-2-one; 2H-chromen-2-one) derivatives are a large class of important naturally occurring and synthetic oxygen-containing heterocycles.

Derivatives as Dual Action HIV-1 Protease and Reverse Transcriptase Inhibitors.
This results in the formation of a big, essential planar heterocyclic ring system with 4.349[degrees] and 5.217[degrees] dihedral angle between the newly formed ether ring and the two original coumarin
