“…Red propolis is a resin collected by bees Apis mellifera from various parts of the plant Dalbergia ecastophyllum, its name derives from the Greek, and means in defense of the hive, because it is used by the bees as much of structural form as for Defense front of insects and micro-organisms (Cabral et al, 2009). The composition of propolis is complex, there are more than 180 identified compounds, deserving highlight the flavonoids, which are used as index of propolis samples qualification and possess antioxidant and antimicrobial (De-Melo et al, 2014). The chemical composition of substances present in propolis varies depending on the location and collection period.…”

The study aimed to evaluate the antimicrobial activity, antioxidant, toxicity and phytochemical screening of the Red Propolis Alagoas. Antimicrobial activity was evaluated by disk diffusion method. Determination of antioxidant activity was performed using the DPPH assay (1.1-diphenyl-2-picrylhydrazyl), FTC (ferric thiocyanate) and determination of phenolic compounds by Follin method. Toxicity was performed by the method of Artemia salina and cytotoxicity by MTT method. The phytochemical screening for the detection of allelochemicals was performed. The ethanol extract of propolis of Alagoas showed significant results for antimicrobial activity, and inhibitory activity for Staphylococcus aureus and Candida krusei. The antioxidant activity of the FTC method was 80% to 108.3% hydrogen peroxide kidnapping, the DPPH method showed an EC50 3.97 mg/mL, the content of total phenolic compounds was determined by calibration curve gallic acid, resulting from 0.0005 mg/100 g of gallic acid equivalent. The extract was non-toxic by A. salina method. The propolis extract showed high activity with a higher percentage than 75% inhibition of tumor cells OVCAR-8, SF-295 and HCT116. Chemical constituents were observed as flavonones, xanthones, flavonols, and Chalcones Auronas, Catechins and leucoanthocyanidins. It is concluded that the extract can be tested is considered a potential source of bioactive metabolites.

The aim of this work was to investigate the organic proprieties in different kinds of ethanolic extracts directly from the market and prepared from raw propolis. The raw propolis was obtained by scraping it from the hives (type 1) and by using a collector to obtain it in strips (type 2). The analysis of phenolic and flavonoid contents was performed, and the oxidative index was obtained. The raw propolis obtained in cities of Southeastern Brazil presented a balsamic aroma, a dark green brownish color was predominant and the consistency was hard or malleable; its origin is from wild flora. Our study pointed out the high variation with on the organic value of propolis, which is a barrier to define a pattern from different types. Type 1 propolis, the easiest to collect, needs some care in good practices, and the commercial extracts need quality control.

“…As sementes são utilizadas na forma de decocto e infuso como contra espasmos musculares (anti-espasmódicas), como emenagogas e para o tratamento de doenças reumáticas (Almeida et al, 2010). A casca do caule mais utilizada é basicamente constituída de cumarina, responsável pelo seu odor peculiar, dos flavonoides isocampferídio, campferol e afrormosina, pelos glicosídios fenólicos amburosídios A e B, dos ácidos fenólicos, ácido vanílico e ácido protocatecuico, além de quantidades abundantes de sacarose (Melo et al, 2014). As cumarinas presente no caule da planta são provavelmente responsáveis, juntamente com outras substâncias, pela ação benéfica das infusões das cascas e pela atividade broncodilatadora determinada experimentalmente, validando cientificamente o uso popular e o tratamento caseiro, especialmente em crianças e idosos (ROQUE &ROCHA, 2010).…”
