“…The minimum requirements according to the Regulation of Identify and Quality of Propolis are 5% (w/w) for phenolic compounds and 0.5% (w/w) for flavonoids (Brazil, 2001). The contents for total phenolics and flavonoids for propolis G6 are lower than those required by Brazilian regulations and are also lower than those reported in the literature for propolis from temperate climates (Ahn et al, 2004;. Despite the low concentrations of these chemi- The correlation between the phenolic composition and biological activities of two varieties of Brazilian propolis (G6 and G12) 561 cal compounds, propolis G6 showed biological activity, which suggests that chemicals other than phenolics and flavonoids in the propolis possess similar biological activities.…”

Biological assays that have been performed on different types of Brazilian propolis have shown that type 6 propolis (G6) has a strong antimicrobial activity and a low flavonoid content. This study aimed to evaluate the correlation between the phenolic composition and the biological activities displayed by propolis G6 from the state of Bahia and green propolis, also known as type 12 (G12). The values of the flavonoids and the total phenolics in propolis G6 were different than those in propolis G12. Although the G12 variety presented greater antioxidant activity, propolis G6 proved to have greater antimicrobial and cytotoxic activities. The results showed that the phenolic compounds may not be the only compounds responsible for the biological activity. More detailed studies of the chemical composition and an assessment of the biological activity are required to establish the quality of propolis.Uniterms: Brazilian própolis/evaluation.

Este trabalho teve como objetivo avaliar a correlação entre a composição fenólica e atividades biológicas apresentadas pela própolis G6, do Estado da Bahia, e a própolis verde, do tipo 12 (G12). Os teores de flavonóides e fenólicos totais na própolis G6 foram diferentes dos teores da própolis G12. Apesar da G12 apresentar maior atividade antioxidante, a própolis G6 apresenta maior atividade antimicrobiana e citotóxica. Os resultados mostraram que os compostos fenólicos não são os únicos compostos responsáveis pela atividade biológica da própolis. Estudos mais específicos da composição química, em adição à avaliação das atividades biológicas, são requeridos para determinar a qualidade da própolis.Unitermos: Própolis brasileira/avaliação.

“…However, in the present study, even larger amounts of phenolic compounds were found (745.69 mg/g). Brazilian propolis samples analyzed in this study also contained more total phenolic content than samples from other countries, such as China (302 ± 4.3 mg/g, Ahn et al, 2007, and 299 ± 0.5 mg/g, Kumazawa et al, 2004), Korea (212.7 ± 7.4 mg/g, Choi et al, 2006), Argentina (187 mg/g, Bankova et al, 2000), India (159.10 ± 0.26 mg/g, Laskar et al, 2010), Portugal (151 ± 0.01 mg/g, Moreira et al, 2008) andThailand (31.2 ± 0.7, Kumazawa et al, 2004).…”

The aim of this study was to analyze the physicochemical properties and antifungal activities of the red propolis samples from Sergipe, Brazil, and also evaluate their variability throughout the year. The characterization of the hydroalcoholic extract (HPE) of the red propolis samples was performed monthly from Dctober 2009 to September 2010. The concentrations of the bioactive compounds varied during the year, but their chromatographic profiles were similar. Four compounds were identified by comparison with authentic standards. Formononetin was one of the predominant compounds in all propolis extracts. In our study, it was observed that all the propolis samples inhibited the growth of Candida species. Multivariate analysis confirmed the variations in chemical composition and color of the HPEs throughout the year. The biological activities of the HPEs were statistically significant (p<0.05), and all samples exhibited antifungal properties.

“…One of the methods widely used is the DPPH scavenging ability (Ahn et al, 2007). The high antioxidant potential for sweet chestnut honeys was cited by other authors, for honeys from Turkey (Küçük et al, 2007;Kolayli et al, 2008;Sarikaya et al, 2009), Italy (Pichichero, Canuti, & Canini, 2009;Giorgi et al, 2011;Perna et al, 2013), and Slovenia (Bertoncelj et al, 2007).…”

A b s t r a c t In recent years, authentic foodstuffs have became a major requirement for consumers and producers worldwide. Honey has increased in popularity since it is associated with a natural diet, and because of honey's authentic origin. The present study investigated the palynological characteristics, physicochemical parameters, total phenol content, flavonoid content, and radical scavenging activity of 41 sweet chestnut (Castanea sativa) honeys from the northwestern part of Spain. These honeys were characterised by high values of electrical conductivity, pH, diastase content, and colour. All the samples showed a pollen combination of Castanea sativa-Rubus-Cytisus type-Erica. Fructose and glucose were 37.2% and 25.9%, while other sugars were less than 5%. Regarding the mineral content K, was the main with a mean value of 260.2 mg/100g. Other elements as Mg with a mean value of 17.1 mg/100g, Ca (mean value of 15.8 mg/100g) and P (mean value of 12.8 mg/100g) were well represented in this honey type. The phenol and flavonoid content were high (mean values of 129.8 mg/100g and 9.0 mg/100g, respectively). Multivariate statistical techniques showed the close relationship of colour, Mg, P, phenols, melezitose, and flavonoids, and the radical scavenging activity.
