Streszczenie:

The present article describes the potential utility of derivative ultraviolet (UV) spectrophotometric technique in the discrimination of different kinds of ignitable liquids in their neat states. Derivative UV spectrophotometry is capable of differentiating these ignitable liquids as derivative spectra have more number of points for comparison than their corresponding normal zero order spectrum. Derivative spectra are relatively simple. The technique is rapid, simple, cost-effective and can be used for the screening purpose at the initial stage of investigation. Taking into account the results

The Bima Brebes, variety of shallots, was in high demand, which led to mixing with other varieties. Derivative spectrophotometric fingerprinting combined with chemometrics was used to distinguish between authentic and adulterated shallot varieties. The objective of this study was to identify the original spectra and their derivative spectrophotometric fingerprinting, as well as classify and differentiate between shallot varieties using chemometrics. UV-Visible (UV-Vis) spectrophotometry was used to test essential oil samples from three shallot varieties and their mixtures, followed by spectral

Comparison of classic and derivative UV spectrophotometric methods for determination of dextromethorphani hydrobromidumA method for the fast determination of dextromethorphani hydrobromidum in pharmaceutical preparations by classic spectrophotometry - zero and first-, second- and third-order derivative spectrophotometry, using "peak - peak" (P - P) and "peak - zero" (P - O) measurements has been performed. The calibration curves are linear within the concentration range of 1.0 - 25.0 μg ml-1 for dextromethorphani hydrobromidum. The procedure is simple, rapid and the results are reliable.

Abstract Four new selective, precise, and accurate methods are described for the determination of nizatidine (NIZ) in the presence of its sulfoxide derivative in both the raw material and pharmaceutical preparations. Method A is based on zero-order (0D), first-derivative (1D), and second-derivative (2D) spectrophotometric measurement of NIZ in aqueous solution at the zero-crossing point of its sulfoxide derivative (at 314, 295334, and 318348 nm, respectively).

Abstract Four simple, rapid, sensitive, and accurate spectrophotometric methods were developed for the simultaneous determination of Allura Red (AR) and Ponceau 4R (P) without previous chemical separation. The first method, derivative spectrophotometry, depends on first derivative spectrophotometry with zero-crossing and peak-to-base measurement. The second method, derivative ratio spectrophotometry, uses the first derivative of the ratio spectra. The ratio spectra are obtained by dividing the absorption spectra of a binary mixture by that of one of the components. The third method, differenti

Abstract A derivative spectrophotometric method was developed to determine NO3– –N in plant tissues. The method is based on measurement of the first-derivative spectrum of nitrosalicylic acid in basic solution. The nitrosalicylic acid was obtained by reaction of samples with salicylic acid in concentrated sulfuric acid and was used by Cataldo et al. in nonderivative spectrophotometry. The main strength of this technique is the lack of matrix background interference, typical of plant extracts in traditional spectrophotometric methods. This method is fast, inexpensive, easy-to-apply, and highly

A consequence of this increased exposure is the 88 to 875-fold amplification of the peroxidase activity in 1-65H over horse heart cytochrome c_. The binding of exogenous ligands to 1-65H inhibited the peroxidase activity thus demonstrating that a

A mode of action involving ring opening of the oxazolidine ring to form an iminium ion which can then alkylate the N2 of guanine has been reinforced by the current computer modeling study. The absolute configuration for quinocarcin should be reversed based on the fact that the optical isomer of the structure arbitrarily assigned in the literature forms a much better binding complex to DNA.

Streszczenie:

Two proteins, hemocyanin from the mollusk A. fulica and BSA, were used to show how the fourth derivatives of UV absorption spectra make it possible to reveal individual proteins characteristics associated with the presence of aromatic amino acids in their composition. To implement the method, the script was developed in the R programming language. This approach can be helpful in solving a variety of problems.

In animal and human organisms, there are many enzymes, members of the family of heme- containing proteins, cytochromes P450 (CYPs), included in the biosynthesis and metabolism of many biomolecules, as cholesterol, bile acids, sex, and corticosteroid hormones, as well as in metabolism of drugs and xenobiotics. It is also well-known that different imidazole and triazole derivatives are efficient inhibitors of CYPs activity. In this study, we present in vitro screening of binding of novel androstane derivatives with tetrazole- containing substituents in position 17 to human recombinant steroid-co

A set of “host” compounds, highly suluble in water, were prepared by the reaction of β-cyclodextrin with propylene oxide in NaOH solution. The reactant ratio was varied in order to examine the difference in the substitution degree of the obtained derivatives. The structure was determined by the 1H-NMR spectra. The average degree of substitution was determined by integration of the corresponding NMR signals of the methyl group, which is part of the hydroxypropyl group and the signal from the proton attached to anomeric carbon of the β-cyclodextrin. The solubility of four different pesticides, v

Increasing resistance of microorganisms to conventional drugs has required scientists to discover new sources of biocides with a broad spectrum of action. Since ancient times, plants and plant derivatives such as essential oils have been used in traditional medicine. In the present study, the ethanolic extracts of the aerial parts (leaves and stem) of Thymus pulegioides were evaluated for their antimicrobial activity against some pathogenic bacteria, Gram+ bacteria: Staphylococcus aureus and Streptococcus pyogenes, respectively Gram- bacteria Escherichia coli. The antibacterial potential was t
