“…Such statement is supported by the research of Koolen et al (2013), which hypothesised a relationship between the absence of antimicrobial activity in buriti phenolic extracts and the concomitant absence (or short concentration) of low polarity compounds, such as unsaturated fatty acids, proven to possess antimicrobial activity (Nazif, 2002). The nature of phenolic compounds present in the extract depends on its polarity; polarity of the extracts is strongly dependent on the conditions prevailing during their preparations, especially the polarity of the solvent selected.…”

a b s t r a c tEight tropical fruit pulps from Brazil were simultaneously characterised in terms of their antioxidant and antimicrobial properties. Antioxidant activity was screened by DPPH radical scavenging activity (126-3987 mg TE/100 g DW) and ferric reduction activity power (368-20819 mg AAE/100 g DW), and complemented with total phenolic content (329-12466 mg GAE/100 g DW) and total flavonoid content measurements (46-672 mg EE /100 g DW), whereas antimicrobial activity was tested against the most frequently found food pathogens.Acerola and açaí presented the highest values for the antioxidant-related measurements. Direct correlations between these measurements could be observed for some of the fruits. Tamarind exhibited the broadest antimicrobial potential, having revealed growth inhibition of Pseudomonas aeruginosa. Escherichia coli, Listeria monocytogenes, Salmonella sp. and Staphylococcus aureus.Açaí and tamarind extracts presented an inverse relationship between antibacterial and antioxidant activities, and therefore, the antibacterial activity cannot be attributed (only) to phenolic compounds.

“…No entanto, os extratos avaliados neste estudo mostraram-se ativos contra cepas Gram positivas e Gram negativas. Os ácidos graxos presentes, principalmente, nos extratos lipofílicos podem ser os responsáveis pela atividade antimicrobiana encontrada nas plantas desse estudo (Hashem;Saleh, 1999;Nazif, 2002). Foram identifi cados oito ácidos graxos diferentes nos extratos de S. oleracea e M. vinifera, como pode ser visto na Tabela 3.…”

RESUMO:As espécies pertencentes à família Palmae são muito interessantes do ponto de vista químico e farmacológico. Neste trabalho, foram estudados os frutos de duas espécies da família Palmae, Syagrus oleracea e Mauritia vinifera. Essas palmeiras foram escolhidas por serem espécies brasileiras, abundantes em nosso país, utilizadas popularmente no tratamento de algumas doenças e ainda pouco estudadas. Foram realizados ensaios farmacológicos para avaliação da atividade antimicrobiana dos extratos dos frutos das duas espécies em estudo. ABSTRACT: "Antimicrobial activity of Syagrus oleracea and Mauritia vinifera fruits". Palmae species are very interesting by the chemical and pharmacological points of view. Two species belonging to this family were chosen to initiate the chemical and pharmacological approach of their fruits: Syagrus oleracea (Martius) Beccari and Mauritia vinifera Martius, known in Brazil as Guariroba and Buriti, respectively. Those palm species can be found in several regions of Brazil, especially at the northeast and southeast of the country. They have been used in folk medicine to treat some diseases, however no toxicological and pharmacological studies have been done so far. For the two studied fruits, the antimicrobial activity tests were carried out by broth microdilution methodology. The objective of this work was to contribute for the pharmacological study of palm species, evaluating the antimicrobial activity of the extracts obtained from the fruits of S. oleracea and M. vinifera. The assays evaluated ethanol extracts of the epicarp/mesocarp of S. oleracea and epicarp/mesocarp of M. vinifera; hexane extract of the endosperm of S. oleracea; hexane and ethyl acetate fractions of the epicarp/mesocarp of S. oleracea, epicarp/mesocarp of M. vinifera and mesocarp/endocarp of M. vinifera. The lipophilic extracts of S. oleracea obtained the best results for the species. For M. vinifera, the lipophilic partitions have shown a high inhibitory percentage for S. aureus. Keywords:Syagrus oleracea, Mauritia vinifera, Palmae, antimicrobial activity. INTRODUÇÃOAs espécies pertencentes à família Palmae, comumente chamadas de palmeiras, são muito interessantes do ponto de vista químico e farmacológico. As palmeiras estão amplamente distribuídas nas zonas temperadas de todo o mundo, principalmente em regiões onde o índice pluviométrico é alto (Cruz, 1965;Zofemler, 1994). Do ponto de vista químico, as plantas dessa família são geralmente não cianogênicas. Os alcalóides (ocasionalmente pirimidínicos) e proantocianidinas podem estar presentes ou não. Os fl avonóides são raros, mas quando presentes são derivados do kaempferol, quercetina, tricina e luteolina. Saponinas e sapogeninas estão ocasionalmente presentes. Éteres metílicos de triterpenos já foram isolados dos frutos de algumas

“…Stigmasterol (7), sitosterol (Stigmast-5-en-3-ol, (8) and betulin (9) were found in three extracts (chloroform, ethyl acetate and butanol extracts). Stigmasterol (7) was present in ethyl acetate extract (15.98%) in large quantities as compared to butanol extract (4.26%) and chloroform extract (0.65%).…”

“…Fruits are used to promote the healing of fresh wounds, and treat dysentery, bronchitis, coughs and tuberculosis [6]. It is also used to relief digestive disorders, obesity, urinary troubles and microbial infections [7,8]. Some pharmacological screening studies indicated that the aqueous extract of Ziziphus spinachristi (L.) root bark has an antinociceptive activity in mice and rats [9] and a central depressant effect in mice [10].…”

Zizyphus spina-christi (L.) (Rhamnaceae family) is a subtropical plant known as 'Nabq' or 'Sidr' which is used for various medicinal purposes. It has used in folk medicine in pain related ailments throughout these regions. Aim of our work is to phytochemically investigate the plant's bark in our laboratory with Chromatographic approach. The crude ethanol extract of dried bark of Z. spina-christi (L.) was fractionated by diethyl ether, chloroform, ethyl acetate and finally with n-butanol. Finally the fractions were investigated for the chemical constituents by using gas chromatography-mass spectrometry. Thirty six compounds from the four fractions of the stem bark of Z. spina-christi (L.) have been identified and recognized, especially betulin, quercetin, stigmasterol, sitosterol, ethyl oleate and phytol by means of GC-MS analyses.
