Diversidade da microbiota de fungos da própolis in natura
Costa, Rodrigo Arthur Fonseca; Bispo, Aline Simões da Rocha; Choupina, Altino; Evangelista-Barreto, Norma Suely; Carvalho, Carlos Alfredo Lopes deO presente estudo teve por objetivo realizar a identificação dos fungos encontrados na própolis produzido por Apis mellifera L. da Baía do Iguape, Brasil. Para tanto, foram utilizadas técnicas morfológicas, bioquímicas e moleculares, sendo averiguado o perfil de restrição gerado por espaçador interno transcrito (ITS1 e ITS4). O tamanho dos produtos de PCR foi analisado quanto ao perfil de restrição obtidos com ...
Antioxidants activity and physicochemical properties of honey from social bees ...
Silva, Irana Paim; Caldas, Maiara Janine Machado; Machado, Cerilene Santiago; Nascimento, Andreia Santos do; Lordêlo, Maurício SantanaThis study compared the nutraceutical potential of Apis mellifera and Melipona quadrifasciata anthidioides honeys from the semiarid region of Bahia, Brazil, using microbiological, melissopalynological, and physicochemical techniques. Total phenols and flavonoids and the antioxidant activity were also determined. All samples had good microbiological quality and safety with an absence of coliforms, Escherichia co...
Use of the electronic tongue as a tool for the characterization of Melipona scu...
Nascimento, Andreia Santos do; Silva, Fabiane de Lima; Machado, Cerilene Santiago; Silva, Samira Maria Peixoto Cavalcante; Estevinho, Leticia M.This study aimed to characterize honey of Melipona scutellaris regarding its physicochemical parameters using the electronic tongue (e-tongue) technique combined with the multivariate statistical analysis for honey differentiation. Physicochemical parameters were evaluated following official methods of chemical analyses. A potentiometric electronic tongue with 16 cross-sensitivity sensors was used for the analy...
Detection of biogenic amines in mead of social bee
Silva, Irana Paim; Dias, L.G.; Silva, Macela Oliveira da; Machado, Cerilene Santiago; Paula, Vanessa B.; Evangelista-Barreto, Norma SuelyMead is an alcoholic beverage, resulting from the fermentation of honey and water, although it is an old drink, some fermentation products are still unknown. Biogenic amines have driven research on food and beverages due to their toxicity and capacity to cause damage to the human health. This study aimed to evaluate the presence of biogenic amines in mead from honey of two species of social bees, using differen...
Storage methods, phenolic composition, and bioactive properties of Apis mellife...
Santa Bárbara, Marivalda F.; Moreira, Manuela M.; Machado, Cerilene Santiago; Chambó, Emerson Dechechi; Pascoal, AnaniasThe aim of this study was to evaluate the influence of lyophilization and drying in stove on phenolic compounds content and the biological activity of Apis mellifera and Trigona spinipes pollens produced in Brazil. In general, the bee pollen produced by T. spinipes presented highest antioxidant activity in dried and fresh samples assessed either by test of plasma ferric reduction capacity (FRAP) and free radica...
Phytochemical study and antioxidant activity of Dalbergia ecastaphyllum
Lucas, Cátia Ionara Santos; Ferreira, Adailton Freitas; Costa, Maria Angélica Carvalho; Silva, Fabiane de Lima; Estevinho, Leticia M.The chemical profile of Dalbergia ecastaphyllum has been indicated as the botanical origin of Brazilian red propolis, an apicultural product with proven therapeutic properties. However, few studies have investigated this plant species. This study evaluated and compared microbiological quality, chemical composition, and antioxidant activity of stem and leaf samples of D. ecastaphyllum. The samples were collected...
Botanical origin, microbiological quality and physicochemical composition of th...
Oliveira, Daiane de Jesus; Santos, Daiane Rodrigues dos; Andrade, Brunelle Ramos; Nascimento, Andreia Santos do; Silva, Macela Oliveira daMelipona scutellaris Latreille, 1811 is of economic importance for local beekeepers, besides its relevance in the pollination of native plant species of the Brazilian Atlantic forest. Currently, data on the use of floral resources by Meliponini colonies are scarce, particularly in urban environments. We evaluated the botanical origin, the microbiological and physicochemical characteristics of pollen stored by M...
Pollen spectrum of honey of Apis mellifera L. and stingless bees (Hymenoptera: ...
Santos, Polyana Carneiro dos; Nascimento, Andreia Santos do; Sodré, Geni da Silva; Carvalho, Carlos Alfredo Lopes de; Alves, Rogério Marcos de OliveiraPollen in honey reflects its botanical origin and melissopalynology is used to identify origin, type, and quantities of pollen grains of the botanical species visited by bees. This study aimed to identify the pollen spectrum of honeys from Apis mellifera and stingless bees produced in the semi-arid region of Bahia, Brazil. We analysed 78 honey samples, which were submitted to the acetolysis process for identifi...
Leaf geometric morphometrics among populations of Dalbergia ecastaphyllum (L.) ...
Morais, Daniel Vieira de; Nunes, Lorena Andrade; Mata, Vandira Pereira da; Costa, Maria Angélica Pereira de Carvalho; Sodré, Geni da SilvaLeaves are plant structures that express important traits of the environment where they live. Leaf description has allowed identification of plant species as well as investigation of abiotic factors effects on their development, such as gases, light, temperature, and herbivory. This study described populations of Dalbergia ecastaphyllum through leaf geometric morphometrics in Brazil. We evaluated 200 leaves fro...
Dalbergia ecastaphyllum leaf extracts: in vitro inhibitory potential against en...
Morais, Daniel Vieira de; Moreira, Manuela Maria; Silva, Fabiane de Lima; Costa, Maria Angélica Pereira de Carvalho; Delerue-Mato, CristinaFor the first time, the anti-hemolytic activity and the enzyme inhibitory activities of Dalbergia ecastaphyllum leaves extracts were tested against α-amylase, α-glucosidase, lipase, acetylcholinesterase, butyrylcholinesterase, tyrosinase and hyaluronidase. The phenolic profile of the obtained extracts was also investigated by high-performance liquid chromatography with photodiode array detection (HPLC-PAD). The...
