“…These results point that the extract have antioxidant activity, justified by the presence of phenolic compounds and flavonoids, known by their capacity to redeem free radicals and inhibit possible oxidant damages. The same antioxidant activity of hidro ethanolic extract of Bysonima crassifolia leaves was previously described by (Pompeu et al, 2012) and for others species of the same genre by (Rolim et al, 2013).…”

“…Studying barks of B. crassifolia, Silva and Rogez (2013), found similar value to the one observed in this paper (208.1 ± 9.7 mg g-1) and superior to the one found by Pompeu et al (2012) that was 58.1 mg g -1 of total phenols for the hydroethanol crude extract of dried leaves of B. crassifolia collected at the region of Belem, PA, Brazil. For the crude extract of aerial parts of B. gardneriana, the values were superiors (425.105 ± 8.523 mg EAG g-1) (Rolim et al, 2013), which suggests that Byrsonima species have high levels of total phenols in their composition. Still, differences found in several studies with B. crassifolia, may be associated to the solvent and the extraction method used (Simões et al, 2010), just like geographic localization and environmental factors form the region where plants are collected may influence the presence and intensity of secondary metabolites (Gobbo-Neto and Lopes, 2007).…”

The use of chemical defensives to control fungal diseases has by consequence to impact negatively over the environment and human health, this way, the use of plant extracts with antifungal properties along with proper cultural management makes viable an alternative plant production control, specially for familiar and organic cultures. The objective of this study was to perform phytochemical and antioxidant analysis of Byrsonima crassifolia (canjiqueira) barks and evaluate its antifungal potential over Fusarium solani and Sclerotinia sclerotiorum mycelial growth. The ethanol extract from plants collected in Pantanal, Mato Grosso do Sul, Brazil was submitted to phytochemical prospection, total phenol and flavonoids quantification and antioxidant activiy determination (DPPH). To evaluate antifungal activity concentrations of 800, 1200, 1600, 2000 and 2400 µg 100 mL -1 of ethanol extract were used. Which concentration was separately incorporated in agar (PDA) and shed in Petri dishes, followed by the fungi mycelial disc where the colonies diameter was measured daily. Negatives control with agar without extract and agar with an ethanol solution were used. The B. crassifolia ethanol extract presented inhibitory activity over the fungi studied where concentrations of 800 and 1600 µg 100 mL -1 , inhibited 38% of the mycelial growth of F. solani; to S. sclerotiorum the best concentration was 2400 µg 100 mL 1 , reducing 37.5%. The antifungal bark extract potential of this specie is attributed to phenolic compounds and to triterpenes derivatives.

The genus Byrsonima belongs to the family Malpighiaceae and is made up of more than 150 species of trees, shrubs, and subshrubs, with broad distribution from Mexico to South America [1]. Approximately 90 species occur in Brazil, 35 of which are found in different areas of the northeastern region of the country, including the state of Pernambuco [2].The use of plants of this genus in northeastern Brazil is common in folk medicine for the treatment of fever, gastrointestinal problems (diarrhea and gastric ulcer), asthma, skin infections, and snake bites [3,4]. Byrsonima sericea DC., known locally as "murici," stands out among the species that occur in the state of Pernambuco with broad distribution in fragments of the Atlantic Rainforest [5].An ethanolic extract from the leaves of B. sericea collected in the state of Ceara (also in northeastern Brazil) has demonstrated gastroprotective properties, and the phytochemical analysis identified triterpenes, tannins, and flavonoids as the main classes of compounds [6]. However, the phytochemical analysis of the leaf essential oil has not yet been investigated. The present study offers the first description of the chemical composition of the essential oil from leaves of B. sericea.The essential oil obtained through conventional hydrodistillation of the fresh leaves of B. sericea exhibited a light green color, and its yield on a fresh weight basis was 0.46 r 0.10%. Forty-two compounds were identified in the essential oil, accounting for 98.58% of the total oil. The oil is basically constituted by monoterpenes (12.69%), sesquiterpenes (29.57%), and phenylpropanoids (56.24%), with apiol (56.11 r 0.71%) and eugenol (0.13 r 0.00%) the only representatives. Other constituents identified in significant amounts were E-caryophyllene (7.32 r 0.20%), trans-E-guaine (4.54 r 0.05%), and D-humulene (3.01 r 0.31%).Fresh leaves from Byrsonima sericea were collected from Cruzinha Woods in the city of Igarassu, state of Pernambuco, in March 2011 in the morning from an adult specimen (10 m in height) without flowers and fruits. The geographical coordinates of the collection site are 07q 49c25, 5cc S and 034q 58c46.6cc W. The plant was identified by botanist Henrique Costa Hermenegildo da Silva from the Federal University of Alagoas (Brazil). A voucher sample was mounted and deposited in the Vasconcelos Sobrinho Herbarium of the Rural Federal University of Pernambuco (Brazil) under number 49312. The extraction of the essential oil through conventional hydrodistillation of the fresh leaves was performed as described previously by Neves and da Camara [7].

Neste trabalho, o estudo fitoquímico e atividade biológica da espécie Banisteriopsis campestris, que é endêmica no Brasil com distribuição geográfica nos Biomas da Caatinga e do Cerrado, foi realizado. O presente trabalho avaliou as atividades antimicrobiana, antifúngica, antioxidante, antileishmania, citotóxica e inibitória contra α-amilase e α-glicosidase, e glicação dos óleos essenciais, extratos e partições de partes da planta, além de caracterizar e/ou determinar a estrutura dos constituintes químicos presentes nas partições e óleos essenciais. Para desenvolvimento do trabalho, extratos etanólicos das folhas, caules e raízes, foram preparados e particionados com solventes de polaridade crescente, gerando as partições de hexano, diclorometano, acetato de etila, n-butanol e a partição residual chamada de metanol/água. Todos os extratos e partições foram submetidos à prospecção fitoquímica, determinação de teores de fenóis totais, proantocianidinas, flavonoides, atividade antioxidante pelos métodos DPPH e ORAC, ensaio de inibição da α-amilase, αglicosidase e glicação, avaliação das atividades antimicrobiana e antifúngica, além das análises dos constituintes presentes nas partições mais ativas por CLAE/EM. Os óleos essenciais das flores, folhas, caules e raízes foram extraídos por hidrodestilação, identificados por CG/EM e realizadas análises de atividade antimicrobiana, antifúngica, antileishmania, antioxidante e citotóxica. Foram identificados por prospecção fitoquímica, terpenos, flavonóides e compostos fenólicos, presentes nos extratos e partições. As partições acetato de etila e n-butanol foram as que exibiram melhores resultados para atividade antioxidante, inibitória para α-amilase e α-glicosidase.A partição acetato de etila das folhas, caule e raiz foram analisadas por CLAE/EM e foram identificadas em suas composições, ácidos orgânicos, flavonoides e procianidinas do tipo B1, B2 e C3. A partição hexano do caule teve excelentes valores de concentração inibitória mínima (CIM) para as bactérias aeróbias e anaeróbias, com valores de CIM abaixo de 50 µ mL -1 contra as bactérias Porphyromonas gingivalis, Fusobacterium nucleatum e Actinomyces naeslundii. Nos óleos essenciais os principais compostos identificados na raiz e caule foram ácidos graxos; nas folhas foram identificadas além destes ácidos graxos, como compostos principais, o alfa terpineol, fitol e esqualeno. O óleo essencial da flor apresentou aproximadamente 9% de monoterpenos, 14,5% de sesquiterpenos destacando-se, alfa-terpineol e (E)-nerolidol.Os óleos essenciais apresentaram atividade antiprotozoária contra Leishmania amazonensis e os óleos do caule e raízes apresentaram baixa citotoxidade contra as linhagens de células Vero. Os óleos também inibiram o crescimento de todas as bactérias orais testadas, com destaque para o óleo das raízes com potente atividade antibacteriana com inibição para todas as espécies de bactérias com valores de CIM variando de 12,5 a 100 μg mL -1 . Os óleos do caule e raízes foram os que exibiram melhores resultados de at...
