“…For this reason, plant sources affect the elemental composition of propolis to a great extent (Lovaković et al 2018). As a result, the elemental content of propolis is used to develop distinctive features and reliable traceability methods of the geographical areas where it was produced as an indicator of environmental pollution (Golubkina et al 2016). In the present study, when the elemental composition of the propolis samples were examined, it was observed that although there were quantitative differences, they had qualitatively similar content.…”

“…Mineral diversity is reflected in the composition of propolis through the transfer of the mineral composition of the soil to the plants from which the propolis is obtained. For this reason, plant sources affect the elemental composition of propolis to a great extent (Lovaković et al 2018). As a result, the elemental content of propolis is used to develop distinctive features and reliable traceability methods of the geographical areas where it was produced as an indicator of environmental pollution (Golubkina et al 2016).…”

The aim of this study was to assess the quality of five propolis samples obtained from Turkey (TP), China (CP), Brazil (BP1, BP2), and Ethiopia (EP). The phenolic compounds of the propolis were identified and quantified using the liquid chromatography-tandem mass spectrometry technique (LC-MS/MS). In addition, quality parameters such as total flavonoid content, total phenolic content, freeradical scavenging activity and element contents were investigated. As a result of LC-MS/MS analysis, the extracts were sorted as TP> BP1> BP2> CP> EP in terms of the total concentration of individual phenolic compounds. Chlorogenic acid was determined as the dominant compound in BP1 and EP, pcoumaric acid as the dominant compound in the BP2 and trans-ferulic acid as the dominant compound in the samples from CP and TP. The concentration of DPPH was higher in TP whereas the ABTS concentration was almost similar to other propolis extracts. The contents of potassium (K), calcium (Ca), iron (Fe), magnesium (Mg) and sodium (Na) in the propolis samples were in the range of 2416.75-14416.02 mg/kg, 8.52-613.25 mg/kg, 102.66-1425.82 mg/kg, 523.84-7336.74 mg/kg and 57.65-191.15 mg/kg, respectively. Consequently, it is again supported that chemical characteristics and activity of propolis varies according to its geographical origin with this study.

With the Legislative Decree n.179 of 21 May 2004 on the unifloral honey's characteristics and with the CEE regulation 2081/92 of DOP denomination (from protect origin), scientific investigations in the agri-food sector started to occupy a prominent position with increasing importance. This area of investigation has been considerably deepened, becoming fundamental in order to consider this term valid, as it is also fundamental for investigation on production chain and denomination, made on various types of products. The morpho-genetic characterization analysis of pollen from honeys, made in the present work, lands itself well to this purpose; with the aim of ascertaining the validity of the wording of "unifloral" applied to some products from the beekeeping industry. Since the implications to which the investigations in the agri-food sector lead to cover not only the purely scientific-agronomic, but also the legal field, it follows the importance of an increasingly scientifically accurate methodology that also allows a faster processing of the sample. The protocol commonly used for pollen characterization of honeys is based on the visual recognition of the pollen present in the sample, their count and statistical analysis of the data obtained. Our method, using Real Time PCR technology, allows a qualitative and quantitative analysis of the pollen species inherent in the sample, thus allowing a fast and accurate analysis of the data that lends itself well to assist the classical research based on visual recognition of pollen.

“…RSA was determined by a method proposed by Tariba Lovaković et al 11 One hundred µL of honey diluted with ultrapure water (1:10) was mixed with 1.9 mL of methanol. Then, 1.5 mL of DPPH methanolic solution (0.18 mM) was added and vortexed vigorously.…”

“…The limited production and respected biological properties make this honey particularly appreciated. 11 Although honeys of different botanical origin, namely polyfloral, 12 lime, 13 sage, 14 acacia, sunflower, linden, basil, buckwheat, oilseed rape and goldenrod 15 have previously been characterized on the basis of their phenolic fraction, to the best of the authors' knowledge no previous studies regarding the detailed polyphenolic profile of strawberry tree honey has been published.…”

Despite of the many beneficial health effects of strawberry tree (Arbutus unedo L.) honey, due to its strong antioxidant activity derived mostly from polyphenols, a detailed phenolic profile has not been previously studied. The aims of this study were to identify the phenolic compounds, determine the total phenolic content (TPC) and evaluate the radical scavenging activity (RSA) of strawberry tree honey from south Croatia. Fifty-two polyphenolics (twenty-seven phenolic acids and twenty-five flavonoids) were identified using ultra-high-performance liquid chromatograph coupled to a hybrid mass spectrometer (LTQ Orbitrap MS). Our overall results point to the higher TPC (1038 mg gallic acid equivalents per kg of honey) and the stronger RSA (3.32 mmol Trolox equivalents per kg of honey) compared to the other monofloral honeys. Due to the presence of large quantities of polyphenolic compounds, strawberry tree honey may have great potential as a health promoting food.
