Studies on GC/MS Spectroscopic Analysis of some Bioactive Antimicrobial Compounds from Cinnamomum zeylanicum
Background: Infectious diarrhoea is an emergent problem in both developing and developed countries for high rates of mortality in infants. In recent years, drug resistance to microbial pathogens has been commonly reported from all over the world. Medicinal plants represent a rich source of antimicrobial agents. Plants are used medicinally in different countries especially in India and are a sou...
متن کاملMushroom tyrosinase inhibition activity of some chromones.
Currently, aloesin is used in the cosmetic industry as a whitening agent because it inhibits tyrosinase activity. Aloesin is a C-glycosylated chromone compound isolated from aloe, and it is difficult to synthesize because of C-glycosyl moiety in the molecule. The purpose of this study is to search for a new chromone compound which is easy to synthesize and which posesses stronger tyrosinase inh...
متن کاملSpectroscopic Studies on Pyrazaboles
The mass spectra of several pyrazaboles of type 1 where R and'or R' = C2H5 have been studied. The loss of boron-bonded hydrocarbon moieties under electron impact is the predominant feature of all spectra. Some ultraviolet and nuclear magnetic resonance data on compounds of type 1 have been collected; bulky substituents were observed to lead to conformational isomers that can be detected by 13C ...

متن کاملSpectroscopic Studies on the Interaction of Nano-TiO2 with Lysozyme
In the present study, the interaction between nano-TiO2 and lysozyme was investigated by the method of UV-Vis detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-TiO2 over the temperature range (293-373) K in different buffer and pH, using temperature scanning spectrosc...
