“…Particularly, FT-Raman methodology is based on the scattering of light from near infrared radiation due to the vibrational energy of the molecules in the sample. FT-Raman has been used in food analysis, namely: quantitative analysis of vitamin A [7]; sugars in honey [8]; determination of erucic acid content in canola oil [9]; detection of vitamins B 2 and B 12 in cereals [10]; classification of different vegetable oils and identifying adulteration on virgin olive [11]; assessment of the quality of Southern Italian honey Types [12]; qualitative analysis of food fraud [10]; controlling protected designation of origin of wine [13].…”

A B S T R A C TThis study aimed to evaluate the potential of FT-Raman spectroscopy in the prediction of the chemical composition of Lavandula spp. monofloral honey. Partial Least Squares (PLS) regression models were performed for the quantitative estimation and the results were correlated with those obtained using reference methods.Good calibration models were obtained for electrical conductivity, ash, total acidity, pH, reducing sugars, hydroxymethylfurfural (HMF), proline, diastase index, apparent sucrose, total flavonoids content and total phenol content. On the other hand, the model was less accurate for pH determination. The calibration models had high r 2 (ranging between 92.8% and 99.9%), high residual prediction deviation -RPD (ranging between 4.2 and 26.8) and low root mean square errors. These results confirm the hypothesis that FT-Raman is a useful technique for the quality control and chemical properties' evaluation of Lavandula spp honey. Its application may allow improving the efficiency, speed and cost of the current laboratory analysis.

“…The normal range of vitamin B12 in plasma of healthy subject is 200-900 pg/mL. Vitamin B12 in plasma, serum and urine can be measured by radioimmunoassay, enzyme-linked immunosorbent assay, microbiological assay (using Lactobacillus leichmannii; Girdwood, 1954), HPLC (Stefova et al, 1997), capillary electrophoresis, mass spectroscopy, Raman spectroscopy (Mayer et al, 1973), Fourier transform Raman spectroscopy (Hancewicz and Petty, 1995), chemiluminescence (Song and Hou, 2003) and fluorescence quenching.…”

High performance liquid chromatography was used to develop and validate the detection of vitamin B12 in blood plasma sample. The mobile phase consists of a mixture of 0.025% trifluroacetic acid in deionized water and 30% methanol. The mixture used was adjusted to pH 2.9 and the flow rate was adjusted to 0.5 mL/min. The separation was achieved using C18 column maintained at 30ºC temperature and detection of vitamin B12 was conducted at maximum wavelength 230 nm.

“…Until now, only a few papers have appeared describing Raman spectroscopy as a means for quantitative analysis of vitamin A. 32 M ost of the time, authors calibrate Raman intensities using a band in their solvent of choice: CCl 4 , hexane, or octanol. [33][34][35][36] Currently, we have added a speci c probe (benzene) to evidence retinol damages during irradiation but also to compare different experiments.…”

Vitamin A is known to support cell growth promotion, maintenance, and differentiation of epithelial tissues. Retinol is currently used in cosmetic formulations and products to deliver these and other benefits to the skin. However, retinol is known to be unstable and, therefore, remains of great concern to the cosmetic industry. The decomposition pathways of the retinoids in general have been previously postulated and investigated mostly by high-performance liquid chromatography (HPLC) with UV/Vis spectroscopy. In our studies, we examined specific conditions at which retinol degrades and subsequently identified and quantified the products of retinol decomposition by Raman spectroscopy. We reveal which experimental settings and computational tools allow monitoring of in situ evolution of an all-trans retinol solution when submitted to UV light in the presence of oxygen.
