“…XRF has been successfully applied in studies on the elemental composition of plants (Chuparina and Gunicheva, 2003;Marguí et al, 2009), soil contamination (Orescanin et al, 2003;Aslan et al, 2004;Marguí et al, 2005;Necemer et al, 2008) and agriculture (Noda et al, 2006;Oliveira et al, 2006;Gratão et al, 2008;Maity et al, 2010), which most of them applied pressed powder pellet to perform EDXRF analysis.…”

Nutrient analysis is used to estimate nutrient content of crop plants to manage fertilizer application for sustained crop production. Direct solid analysis of agricultural and environmental samples by energy dispersive X-ray fluorescence spectrometry (EDXRF) was chosen as alternative technique to evaluate the simultaneous multielemental quantification of the most important essential elements in coffee (Coffea arabica L.) plants. Inductively coupled plasma atomic emission spectrometry and certified reference materials made from leaves were used to calibrate and check the trueness of EDXRF method for the determination of the concentration of several nutrients in coffee leaves and branches. Fluorescence spectrometry proved to be advantageous and presented low cost as loose powder samples could be used. Samples collected from a field experiment where coffee plants were treated with excess of Ni and Zn were used to verify the practical application of the method. Good relationships were achieved between certified values and data obtained by EDXRF, with recoveries ranging from 82 to 117 %.

“…Pellets made from 0.5 g to 1.0 g of powdered sample material were analysed using an EDXRF spectrometer composed of a Si (Li) detector, a spectroscopy amplifier, an analog to digital converter and a PC-based multichannel analyser (Canberra). The analysis of complex X-ray spectra was performed using the AXIL (Nečemer et al, 2008) spectral analysis program. Quantification was performed using the in-house developed QAES (Quantitative Analysis of Environmental Samples) software (Nečemer et al, 2011).…”

Common buckwheat (Fagopyrum esculentum Moench) and tartary buckwheat (Fagopyrum tataricum Gaerth.) are underutilized pseudo-cereals and both considered nutritional food. Eight common and eleven tartary buckwheat accessions acquired from Slovenian plant gene bank were grown at the experimental fields of the Agricultural Institute of Slovenia in 2014. Dried grains were homogenised and analysed for several nutrient parameters: moisture content (11-14% dry weight, DW), total proteins (11-16 % DW), dietary fibre (15-19 % DW), ash (2-6 % DW) and total fats (1.8-2.6 % DW). The fatty acids (C14:0, C16:0, C18:0, C18:1n9, C18:2n6, C18:3n3, C20:0) were determined using gas chromatography, free amino acids (Gly, Glu, Arg, Lys, Asp, Ser, Phe, Ala, Val, Thr, Pro, Ile, Met, His, Cys, Leu, Tyr) by the highperformance liquid chromatography and multi-mineral analysis (K, P, Si, S, Ca, Fe, Cl, Ti, Zn) using X-ray fluorescence spectroscopy. The results show significant differences between two buckwheat species, and their gene bank accessions for investigated nutritional parameters.

“…The complex X-ray spectra were examined by the analysis of x-ray spectra by iterative least square fitting (AXIL) (33) program. The evaluated uncertainty of this procedure included the statistical uncertainty of the measured intensities and the uncertainty of the mathematical fitting procedure.…”

“…The overall uncertainty of the spectral measurement and analysis was in most cases less than 1 %. Quantification was then performed using the Quantitative Analysis of Environmental Samples (QAES) software developed by Nečemer et al (33,34). The estimated uncertainty of the analysis was around 5 to 10 %.…”

SummaryThis study characterises the genetic variability of local pomegranate (Punica granatum L.) germplasm from the Slovenian and Croatian areas of Istria. The bioactive components and antioxidant and antimicrobial properties of ethanol and water extracts of different parts of pomegranate fruit were also determined, along with their preliminary nutritional characterisation. Twenty-six different genotypes identified with microsatellite analysis indicate the great diversity of pomegranate in Istria. The pomegranate fruit ethanol extracts represent rich sources of phenolic compounds (mean value of the mass fraction in exocarp and mesocarp expressed as gallic acid is 23 and 16 mg/g, respectively). The ethanol extracts of pomegranate exocarp and mesocarp showed the greatest antimicrobial activity against Candida albicans, Candida parapsilosis, Rhodotorula mucilaginosa, Exophiala dermatitidis and Staphylococcus aureus, and the same water extracts against S. aureus and Escherichia coli. To the best of our knowledge, this study represents the first report of the characterisation of pomegranate genetic resources from Istria at different levels, including the molecular, chemical, antimicrobial and nutritional properties.
