“…Finger et al (2014) studied the concentrations of 11 representative metals in some regions of the Paraná state in South Brazil, and they demonstrated that the concentrations of aluminum (Al), Ca, and Mg differed in some regions, which could be used to identify not only the geographical origin of propolis, and to identification of specific zones with environmental contamination. Similar studies have been undertaken in other countries such as those by Cantarelli et al (2011) in Argentina, Gong et al (2012) in China, and Bonvehí and Bermejo (2013) in Spain.…”

The effects of seasonal variations and the methods of collection of propolis produced by Africanized honey bees Apis mellifera Linnaeus, 1758, on the composition of constituent minerals such as magnesium (Mg), zinc (Zn), iron (Fe), sodium (Na), calcium (Ca), copper (Cu), and potassium (K) were evaluated. Propolis was harvested from 25 beehives by scraping or by means of propolis collectors (screen, "intelligent" collector propolis [ICP], lateral opening of the super [LOS], and underlay method). During the one-year study, the propolis produced was harvested each month, ground, homogenized, and stored in a freezer at -10 ºC. Seasonal analyses of the mineral composition were carried out by atomic absorption spectrophotometry and the results were evaluated by analysis of variance (ANOVA), followed by Tukey-Kramer's test to compare the mean values (p<0.05). The results showed that seasonal variations influence the contents of 5 minerals (Mg, Fe, Na, Ca, and Cu), and the propolis harvesting method affects the contents of 4 minerals (Mg, Zn, Fe, and Ca).Keywords: seasonality, macro-and micro-mineral, propolis collectors, spectrophotometry, quality. Efeitos de variações sazonais e métodos de coleta sobre a composição mineral de própolis de colmeias de Apis mellifera Linnaeus ResumoA influência da sazonalidade e de métodos de produção de própolis por abelhas africanizadas Apis mellifera Linnaeus, 1758, sobre a concentração de magnésio (Mg), zinco (Zn), ferro (Fe), sódio (Na), cálcio (Ca), cobre (Cu) e potássio (K) foram avaliados. 25 colmeias foram utilizadas, e a colheita de propolis ocorreu por raspagem ou a partir de coletores (tela, coletor de própolis "inteligente" -CPI, abertura lateral da melgueira -ALM e calço). Durante um ano a própolis foi colhida mensalmente, homogeneizada e armazenada em freezer a -10 ºC. A análise sazonal de minerais foi realizada por espectrofotometria de absorção atômica e os resultados avaliados por análise de variância (ANOVA) seguida do teste de Tukey-Kramer para comparação de médias (p<0,05). Os resultados demostraram que a sazonalidade afetou o conteúdo de cinco minerais (Mg, Fe, Na, Ca e Cu) e os métodos de coleta afetaram o conteúdo de quatro minerais (Mg, Zn, Fe e Ca).Palavras-chave: sazonalidade, macro e micro-minerais, coletores de própolis, espectrofotometria, qualidade.

“…Zinc is the second most abundant transition metal usually found in raw propolis, in concentrations ranging from 10 to 200 mg/kg and being surpassed only by iron, which is found in at least 10‐fold higher concentration than that of zinc. Samples of raw propolis containing unusually high Zn concentrations of 1364 or 9325 mg/kg have been reported . Whereas zinc plays multiple roles in cell biology and is an essential element for a wide variety of living beings, including humans and microorganisms, there has been a great deal of efforts lately to develop Zn‐based complexes as antimicrobial agents and cancer experimental therapeutics.…”

“…Also, mineral composition was determined in Croatian propolis samples by AAS . Neutron Activation Analysis (NAA) in order to characterize raw propolis from Argentina, prior mineralization of the sample was performed . Although these methodologies provided solid data on Zn content in raw propolis, they require expensive instrumentation.…”

A porphyrin‐based fluorescence method for zinc determination in commercial propolis extracts without sample pretreatment

The quantification of zinc in over-the-counter drugs as commercial propolis extracts by molecular fluorescence technique using meso-tetrakis(4-carboxyphenyl)porphyrin (H TCPP ) was developed for the first time. The calibration curve is linear from 6.60 to 100 nmol L of Zn . The detection and quantification limits were 6.22 nmol L and 19.0 nmol L , respectively. The reproducibility and repeatability calculated as the percentage variation of slopes of seven calibration curves were 6.75% and 4.61%, respectively. Commercial propolis extract samples from four Brazilian states were analyzed and the results (0.329-0.797 mg/100 mL) obtained with this method are in good agreement with that obtained with the Atomic Absorption Spectroscopy (AAS) technique. The method is simple, fast, of low cost and allows the analysis of the samples without pretreatment. Moreover the major advantage is that Zn-porphyrin complex presents fluorescent characteristic promoting the selectivity and sensitivity of the method.
