Quality of propolis commercialized in the informal market

In VitroEvaluation of the Potential Use of Propolis as a Multitarget Therapeutic Product: Physicochemical Properties, Chemical Composition, and Immunomodulatory, Antibacterial, and Anticancer Properties

“…e moisture of the studied propolis sample was 1.01 ± 0.01%; this value is within the limit established by the Brazilian legislation (not more than 8%) [41]. e pH was somewhat acidic (5.1 ± 0.11), and it was similar to propolis pH found in other studies [43,44].…”

Evaluation of the influence of seasonality and landscape on the physicochemical characteristics of propolis

“…The dry extract values of the Brazilian propolis samples evaluated were higher than that established by the Brazilian legislation (FUNARI; FERRO, 2006;SOUZA et al, 2010;TAGLIACOLLO;ORSI, 2011), in terms of quality. However, for the flood plain propolis, the dry extract content was smaller at 11% (Table 2), which can be attributed to the landscape in the Pantanal of Cáceres, MT.…”

“…The content of flavonoids of the Brazilian propolis exhibited quality in other areas of the States of Rio Grande do Sul (ALVES; KUBOTA, 2013) and São Paulo (COSTA et al, 2008;FUNARI;FERRO, 2006;TAGLIACOLLO;ORSI, 2011).…”

“…However, some researches consider this propolis as having physicochemical quality with values higher than those established by Brazilian legislation, with an oxidation index between 3.0 a 54 according to Sousa et al (2007) and Tagliacollo and Orsi (2011).…”

Phenols, flavonoids and antioxidant activity of aqueous and methanolic extracts of propolis (Apis mellifera L.) from Algarve, South Portugal

“…In Brazil, there is legislation to regulate the quality of ethanol extract of propolis (Tagliacollo & Orsi, 2011); however, in Portugal, only very recently has there been studies concerning the chemical and biological properties of propolis from Portugal (Falcão et al, 2010;Miguel et al, 2010;Cardoso et al, 2011;Valente et al, 2011;Silva et al, 2012).…”
