“…The determination of total phenolic content and antioxidant capacity in coloured and white rice varieties from Thailand using Fourier transform infrared (FTMIR) spectroscopy was reported [ 29 ]. Dark glutinous rice had the highest level of antioxidant capacity and phytochemicals followed by red rice, brown rice, and white rice as indicated by the levels of phenolic content in rice samples [ 29 ]. Hierarchical cluster analysis based on selected principal components from a principal component analysis (PCA) discriminated rice varieties according to their color [ 29 ].…”

Spectroscopic methods provide with very useful qualitative and quantitative information about the biochemistry and chemistry of antioxidants. Near infrared (NIR) and mid infrared (MIR) spectroscopy are considered as powerful, fast, accurate and non-destructive analytical tools that can be considered as a replacement of traditional chemical analysis. In recent years, several reports can be found in the literature demonstrating the usefulness of these methods in the analysis of antioxidants in different organic matrices. This article reviews recent applications of infrared (NIR and MIR) spectroscopy in the analysis of antioxidant compounds in a wide range of samples such as agricultural products, foods and plants.

The present study explores an alternative method for antioxidants determination in buckwheat (Fagopyrum) samples. Buckwheat contains different amounts of the antioxidants rutin, quercetin and quercitrin in different plant parts. Buckwheat seeds are most commonly used as food; however, preparations from the herb can also be used as a rich source of rutin. Infrared spectroscopy was used for individual and sum quantification of rutin, quercetin and quercitrin in whole and ground flowers and leaves of seven different buckwheat species. Correlation coefficients R of calibration and independent validation set for rutin, quercetin and quercitrin were 1.00 and 0.98, 0.94 and 0.99, 0.99 and 0.95, respectively. Some of the developed models had accuracy comparable to the reference HPLC method. Additionally many different parameters that give an important insight into the FTIR technique are discussed (different plant parts, whole and ground untreated samples, 3 different resolutions, 7 spectra pre-treatments, using individual or averaged spectra, reducing spectral data input, considering additional non-spectral data). The implemented technique used no sample preparation, is non-destructive and uses very little amounts of sample. Result show that infrared spectroscopy can be a fast and environmentally friendly alternative technique for routine analysis of main flavonoids in aerial parts of buckwheat.

Hairy root cultures (HRCs) are characterized by fast and unlimited root growth, and they have greater genetic stability than other cultivation methods. HRCs are known to accumulate phytochemical levels comparable to those of intact plant. In this study, HRCs of Polygonum multiflorum were established from leaf explants infected with Agrobacterium rhizogenes strain KCCM 11879. Over 60% of the explants showed hairy root induction after 21 days of cultivation on hormone-free MS (Murashige and Skoog Physiol Plant 15:473-479, 1962) medium; induced roots were confirmed by PCR using a rolC-specific primer. Of the six lines of HRCs selected for further analysis, line HR-01 performed best, producing a root biomass (105.2 g L of FW, 9.7 g L of DW), which is 10-fold higher than that of non-transgenic roots. The HR-01 line also showed a significant increase in its total phenolic content (26.64 mg g DW), while non-transgenic roots accumulated 8.36 mg g DW of total phenolic. The levels of phenolic compounds in the HRCs increased more than 2.5-fold following exposure to 50 μM methyl jasmonate for 5 days. Fourier transform infrared (FT-IR) spectroscopic analysis of bioactive accumulation in P. multiflorum enabled discrimination between hairy root and adventitious root cultures. Thus, it is evident from this study that HRCs could be an attractive proposition for large-scale production of root biomass and secondary metabolites of P. multiflorum in bioreactors.
