Quality Control of Valerianae Radix by Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) Spectroscopy.
(Acetoxy-)valerenic acid and total essential oil content are important quality attributes of pharmacy grade valerian root (Valerianae radix). Traditional analysis of these quantities is time-consuming and necessitates (harmful) solvents. Here we investigated an application of attenuated total reflection Fourier transform infrared spectroscopy for extractionless analysis of these quality attribu...
متن کاملDocosahexaenoic Acid Ester Degradation Measured by FTIR-ATR with Correlation Spectroscopy
Highly unsaturated fatty acids such as docosahexaenoic acid and linolenic acid are prone to oxidation with a resulting loss of bioactivity and generation of malodorous degradation compounds. Degradation proceeds by formation of the corresponding hydroperoxyl free radical with subsequent oxidative cleavage at the double bond site. FTIR-ATR was used to detect degradation through spectral changes ...
متن کاملThe infrared spectra of matrix isolated uranium oxide species
The infrared spectra of matrix isolated uranium oxides have been studied by several investigators [1-6].1 Although the spectra were similar, these workers differed in their interpretation and assignm.ent of the observed bands. In particular, AbramoWItz et a1. [1, 2]; and Leary et a1. [3]; assigned two absorption bands at 873 and 776 cml to UOz and UO while Carstens et al. [4], and Gabelnick et ...
متن کاملEvaluating the Role of antioxidants in the stabilization of hydroxypropyl cellulose by ATR-FTIR Spectroscopy
This study is aimed at evaluating the performance of tetrakismethylene-3-3,5-di-tert-butyl-4-hydroxyphenyl propionate methane S1010, tris2,4-di-tert-butylphenyl phosphite S1680 and ascorbic acid AA antioxidants in stabilization of hydroxypropyl cellulose HPC. For this purpose, a number of films with weight percent ratios of 0.4 w/w were prepared in a 1 isopropanol solution w/v. Then, the films ...
متن کاملAtr-ftir Spectrometry Characterisation of Polymeric Materials
The qualitative study on the efficiency of anti-caking and antioxidant additives as long-term thermal stabilizers for polypropylene (PP) using ATR-FTIR spectrometry is reported. Different kinds of additives are used in polymeric materials both for processing, for long-term stabilization and to prevent deterioration of the plastics performance. ATR-FTIR technique is one of the most important spe...
