“…This is the same area as the stretching vibration region for carbon and aromatic C-H groups [23]. Therefore, carboxylic acids are characterized by an irregular character of absorption in 3300-2500 cm -1 with a wide range of the O-H stretching vibration band for C-H [12]. Strong hydrogen bonds present in dimeric carboxylic acids are the reason for the significant extension of the band stretching vibration of the OH group [24].…”

“…Typically, the characteristic differences in the FTIR spectral analysis for natural honeys were observed. It was probably related to the content of carboxylic acids in different types of honey resulting from the floral origin, geographic location and possible environmental pollution [2,[12][13][14][15][16][17]. Similarly as for alcohols, the O-H stretching vibration band in carboxylic acids is very broad and occurs in the field of 3300-2500 cm -1 [18][19][20][21][22] with the maximum at 3000 cm -1 .…”

Abstract. Every kind of honey is a very precious natural product which is made by Mellifera bees species. The chemical composition of honey depends on its origin or mode of production. Honey consists essentially of different sugars, predominantly fructose and glucose. There are also nonsugar ingredients like proteins and amino acids, as well as some kind of enzymes, such as: invertase, amylase, glucose oxidase, catalase and phosphatase. The fact that honey is one of the oldest medicine known worldwide is remarkable. Scientists all over the world have been trying to improve analytical methods as well as to implement new ones in order to reaffirm the high quality of honey the benefits of which may be distracted or disturbed. There are many methods and popular analytical techniques, including as follows: mass spectroscopy and molecular spectroscopy (especially FTIR spectroscopy). The infrared spectroscopy technique is one of the most common analytical methods which are used to analyse honey nowadays. The main aim of the task was to use ATR-FTIR infrared spectroscopy to compare selected honey samples as well as typical sequences coming out from certain functional groups in the analysed samples.

“…The small bands at 1342 and 1411 cm -1 were due to O-H bending of the C-OH group and combination of O-H bending of the C-OH group and C-H bending of the alkenes (Anjos et al, 2015). Further information on band assignment of infrared vibrations of honey can be found elsewhere (Gok et al, 2015). In Figure1b, the major bands highlighted at 1910 nm was attributed to O-H stretch and bend vibrations and the band at 2074 nm was attributed to O-H deformation and C-O stretch vibrations (Osborne et al, 1993).…”

The objective of this study was to develop a rapid infrared technique to determine 10 key quality parameters (sucrose, glucose, fructose, reducing sugar, 5-HMF, °Brix, moisture content, water activity, pH and free acidity) in honey by using new generation portable and handheld devices. The composition of honey samples (n=59) collected from different parts of Turkey was analyzed by using established reference methods, giving wide range of concentrations for each parameter. The levels of sucrose and 5-HMF in some samples were above the established regulatory limits (Codex Alimentarius and European Union standards), indicating possible adulteration or process and storage abuse. Spectra were collected by using portable Fourier-Transformed infrared (FTIR) and handheld NIR (Near Infrared) spectrometers. Partial least squares regression (PLSR) approach was used to correlate the spectral features with compositional reference values, giving strong linear correlation coefficients and standard errors of prediction. Although both systems performed similarly, portable FTIR system was superior in predictions of sucrose, 5-HMF and free acidity while portable NIR system performed noticeably better for °Brix and moisture content. The data indicates that all of the 10 parameters can be measured within the minutes using both systems, providing reliable screening capabilities, flexibility and the potential for in-field applications.

“…22 In order to interpret the huge databases of results obtained for determining elements in medicinal herbs or in other materials of natural origin, such as tea samples or honeys, multivariate statistical methods are very often required. [23][24][25][26][27] Based on the experimental results obtained by high performance liquid chromatography (HPLC) technique with various detection systems, it was found that after the application of principal component analysis (PCA) and cluster analysis (CA), samples of medicinal plants representing three botanical species, Equisetum, Polygonum and Viola, were always grouped together. This observation indicates a similar chemical composition.…”

Essential and toxic metals were determined in eighteen samples of medicinal herbs from Poland, Lithuania and Serbia by means of laser-induced breakdown spectroscopy (LIBS) and inductively coupled plasma optical emission spectrometry (ICP OES). Calcium, K and Mg concentrations were obtained in % (m/m) and other metals (Na, Co, Cu, Fe, Mn, Ni, Zn, Cd, Cr and Pb) in mg kg -1. The fact that the herb samples analyzed belonged to specific plant species and represented different morphological plant parts explained the characteristic distribution in two-dimensional scores plots obtained by principal component analysis (PCA). A strong correlation of LIBS results was achieved in comparison to those obtained by ICP OES for Ca, K and Mg. Differences in the types of infusions were observed, in that leaves are related to Zn and Ni concentrations, leaves and flowers to Co, Ca and Mn concentrations and flowers to K, Na, Mg and Fe content.
