The synergistic effect of higher chromatographic resolution (from GC × GC), spectral deconvolution and acquisition of full spectra (from TOFMS) allows the GC × GC-TOFMS system

The proposed differential pulse voltammetric method was adequate for the determination of sibutramine as indicated by the results achieved in the analysis of

The uncertainties related to transport and storage, investigated by the respectively short-term and long-term studies, were calculated through a spreadsheet that includes

19-21 Despite of its lower sensitivity, the kinetic release using the Bradford assay resulted in similar behavior using the fluoresca- mine method (Figures 3C and 3D).

The lupeol content means obtained for sample powdered plant material, hydroalcoholic extract, and dried extract are shown in the Table 3.. A HPLC method for the

Based on the interest in the above biological activities exhibited by the pyrazoline and pyrimidine compounds, we report here the synthesis of a new series of pyrazoline and

The structural characterization of the compounds isolated was established based on infrared spectroscopy, mass spectrometry, one- and two-dimensional nuclear magnetic resonance,

The structures of the new compounds were elucidated with the help of 1D and 2D nuclear magnetic resonance (NMR) and infrared spectroscopy together with high resolution
