“…In the same manner, the inhibiting capacity of linoleic acid/β-carotene is greater inChile (54.7-88.1% inhibition), in this case followed by Galicia (72.7-83.3% inhibition),and the lowest value occurs in Castilla y León (21.6-82.2% inhibition).The values found for flavones and flavonolswere in generalhigher than those found in Chinese samples [19],by authors who used quercetin as a reference, while the values of this study are lower than those found in propolis from Mexicowhen using rutin as a reference [13]. For the contents of flavanones and dihydroflavonolsresults found in Spanishpropolissamples are higher than those found in propolis from Mexico [13], Portugal [15], and Argentina [25].As far as antioxidant activity is concerned, the closest ABTS values to those found in this study were found in Turkish propolis [20].Finally, the results of the antioxidant capacitydetermined by thelinoleic acid/β-carotene method of this study are in line with those found in various locations inChina [19], and similar to those found byKumazawain countries such as Argentina [23], Australia, Chile, China, and Hungary, which are higher than propolis values fromBrazil [26] andKorea [27], (Table 1).…”

“…The determination offlavanones anddihydroflavonolsin propolis by means of spectrophotometric methods [14]is based on the reaction of these compounds to 3.4-dinitrophenylhydrazine (DNP) to obtain coloured yellowphenylhydrazone usingpinocembrin as a reference [12,15].As for the individualised quantification of these compounds, it is carried out by chromatography [12,[16][17][18].The antioxidant capacity of raw propolis can be determined by various methods. In numerous studies therefore the inhibiting activity of the ABTS radical is measured usingTroloxas a reference [19][20][21][22].In the same manner the determination of the antioxidant capacity, measured as an inhibiting activity of the linoleic acid/β-carotene radical using Trolox as a method of reference, has been applied to determination in propolis by the authors [19,[23][24][25][26][27].NIR spectrometry could hence be an effective and rapid method for the quality determination of propolis. However, there are few studies evaluating the potential of near infrared spectroscopy (NIR) for quantitative analysis of propolis.…”

Propolis is a bee product widely used as a dietary supplement and included in sweets or baby foods due to its well-known antioxidant and nutritional properties that are directly correlated with its phenolic composition. For this reason, this study analysed the total contents of flavones and flavonols, flavanones and dihydroflavonols, and the antioxidant capacity by using the methods of ABTS and linoleic acid/β-carotene in 99 samples of propolis from Spain and Chile. A rapid method was developed for quantifying these parameters in raw propolis using near infrared (NIR) spectroscopy with an optical fibre probe of remote reflectance applied directly to the ground up sample. The models developed allow the determination of the total of flavones and flavonols (0-183 mg rutin/ g propolis), of the total of flavanones and dihydroflavonols (9-109 mg pinocembrin/ g propolis extract), and the antioxidant capacity by the ABTS method (0-3212 nmolesTrolox/ mg of propolis) and of linoleic acid/β-carotene (22-86% inhibition). The NIR spectroscopy models were applied in external validation to different samples of the calibration group, which led to the conclusion that the methods developed provide significantly identical data to the initial chemical data of reference.

Propolis Extract in Postharvest Conservation Banana ' Prata'

et al. 2016

-In the present work were evaluated the effects of propolis coatings of various botanical sources on quality traits of bananas cv. Prata (Musa sapientum L.) stored at room temperature. ´Prata´ bananas were selected and submitted to five postharvest treatments: four coatings applied by immersion in propolis extracts at a concentration of 2.5% (w/v) and a control (without coating). Propolis extracts were applied as 1) a wild type aqueous propolis extract, 2) a wild type hydroalcoholic propolis extract, 3) a rosemary green type hydroalcoholic propolis extract and 4) a red type hydroalcoholic propolis extract. The bananas were evaluated at three-day intervals along 12 days for fresh weight losses, flesh firmness, soluble solids (SS), titratable acidity (TA), the ratio SS/TA and pH. Sensory analyses were performed after three and six days of storage by 55 not trained panelists designed for acceptability. At the end of the twelve-day storage period, bananas coated either with the rosemary green hydroalcoholic extract or with the aqueous extract presented lower fresh weight losses in comparison to the bananas of the control treatment. No differences were determined in relation to flesh firmness and along the storage period TA values decreased and pH values increased in bananas of all treatments. SS contents increased towards the end of the storage period that, consequently, contributed to increases in the SS/TA ratio. The most significant increase in SS/TA ratio was determined in bananas coated with the red type hydroalcoholic extract. Taste panelists did not detect significant differences amongst coated and not coated cv. Prata bananas up to six days of storage. Index terms: Musa sp., hydroalcoholic extract, taste panel, fruit acceptability, storage. EXTRATO DE PRÓPOLIS NA CONSERVAÇÃO PÓS-COLHEITA DE BANANA 'PRATA'RESUMO -Este trabalho foi realizado com o objetivo de avaliar os efeitos do revestimento com extrato de própolis de diferentes fontes botânicas sobre as características físico-químicas de banana 'Prata' (Musa sapientum L.), armazenada à temperatura ambiente. Bananas 'Prata' foram selecionadas e submetidas à cinco tratamentos pós-colheita, sendo quatro formas de revestimento por imersão em extrato de própolis de diferentes fontes botânicas com concentração de 2,5% (m/v) ("extrato aquoso de própolis do tipo silvestre", "extrato hidroalcoólico de própolis do tipo silvestre", "extrato hidroalcoólico de própolis do tipo verde alecrim e "extrato hidroalcoólico de própolis do tipo vermelho ") e um controle (sem revestimento). As variáveis avaliadas foram perda de massa, firmeza da polpa, sólidos solúveis (SS), acidez titulável (AT), relação entre sólidos solúveis e acidez titulável (SS/AT) e potencial hidrogeniônico (pH), realizadas em intervalos de 3 dias por 12 dias de armazenamento. Realizou-se a análise sensorial das bananas aos 3 e 6 dias de armazenamento, avaliadas por 55 provadores não treinados através do teste de aceitação. Ao final de 12 dias de armazenamento, os revestimentos de extrato de própo...

“…Sua composição química é bastante variável e complexa, estando relacionado com a fitogeografia da região (Castro et al, 2007;Sousa et al, 2007;Buriol et al, 2009;Cabral et al, 2009). Estudos realizados em distintas espécies evidenciaram que a própolis possui diversas propriedades biológicas, como antifúngica, anti-tumoral, antibacteriana (Araújo et al, 2012;Mannani et al, 2012;Kuropatnicki et al, 2013), antiinflamatória (Moura et al, 2009), cicatrizante (Souza et al, 2009), antiulcerogênica (Barros et al, 2008), antiparasitária (Pontin et al, 2008) e antioxidante (Oldoni et al, 2011), imunoestimulatória (Sforcin et al, 2005, Missima & Sforcin, 2008.…”
