“…Silva (2009) found that the essential oil of the leaves of Hydrocotyle bonariensis, which is rich in monoterpenes (58.1%), such as (+)-limonene, exerts allelopathic effects on the germination and growth of lettuce and onion. Some ethanol extracts and semipurified fractions obtained from species of the cerrado also exhibit herbicidal effects (Peres et al 2009;Candido et al 2010). Phytotoxic and antioxidant activity of seven native fruits of Brazil Among the species cited in the present study, those that presented the greatest antioxidant potential were Acrocomia aculeata (peel), Tamarindus indica (peel), Byrsonima intermedia (whole fruit) and Psidium firmum (whole fruit).…”

We investigated antioxidant capacity, phenolic content and phytotoxic effects in seven species of fruit native to Brazil: Acrocomia aculeata, Hymenaea stigonocarpa, Tamarindus indica, Byrsonima intermedia, Psidium firmum, Myrciaria cauliflora and Ficus obtusifolia. Phytotoxic effects were assessed from crude ethanol extracts and semipurified fractions. In four of the seven fruits, total phenolic content, as determined by Folin-Ciocalteu assay, was higher in the peel than in the pulp. We found that total phenolic content correlated significantly with antioxidant capacity. High-performance liquid chromatography with diode array detection revealed the presence of the flavonoids quercetin and rutin in some fruits. We also evaluated the allelopathic effects of the crude ethanol extract and semipurified fractions. In most of the essays, the ethyl acetate fractions showed the highest level of activity.

“…The presence of phenolics in extracts of Dicksonia sellowiana may contribute directly to its antioxidant properties (Duh et al, 1999;Bora et al, 2005). Ethanolic and ethyl acetate extracts showed good antioxidant action based on the DPPH radical scavenging assay in Microgramma vacciniifolia (Peres et al, 2009). According to Hort et al (2008), the antioxidant activity and hepatoprotective potential of crude extracts are based on organic solvents of increasing polarity.…”

Abstract:The aim of this review was to explore the pharmacological activity of early tracheophytes (pteridophytes) as an alternative medicine for treating human ailments. As the first vascular plants, pteridophytes (aka, ferns and fern allies) are an ancient lineage, and human beings have been exploring and using taxa from this lineage for over 2000 years because of their beneficial properties. We have documented the medicinal uses of pteridophytes belonging to thirty different families. The lycophyte Selaginella sp. was shown in earlier studies to have multiple pharmacological activity, such as antioxidant, anti-inflammatory, anti-cancer, antidiabetic, antiviral, antimicrobial, and anti-Alzheimer properties. Among all the pteridophytes examined, taxa from the Pteridaceae, Polypodiaceae, and Adiantaceae exhibited significant medicinal activity. Based on our review, many pteridophytes have properties that could be used in alternative medicine for treatment of various human illnesses. Biotechnological tools can be used to preserve and even improve their bioactive molecules for the preparation of medicines against illness. Even though several studies have reported medicinal uses of ferns, the possible bioactive compounds of several pteridophytes have not been identified. Furthermore, their optimal dosage level and treatment strategies still need to be determined. Finally, the future direction of pteridophyte research is discussed.

“…For example, species of the genus Microgramma present a long-crawling rhizome that allows the occupation of extensive areas in the forophytes (Waechter 1998;Kersten and Silva, 2001). Specifically, M. vaccinifolia could have taken the highest IVs due to its aleopathic potential (Peres et al 2009) and this species is cyanogenic, what can be reducing the predation (Santos et al, 2005) and increase its population. Microgramma squamulosa has a high sclerophylly index (Rocha et al, 2013), stomatal density and higher thickness of hypoderm in more polluted environments , and these adaptations are important under water stress (Fahn and Cutler, 1992).…”

Riparian forests are heterogeneous environments, in which epiphytes find ideal conditions to develop. These plants absorb the necessary nutrients for survival from the atmosphere, and their occurrence and distribution can be influenced by the quality and quantity of precipitation. The objective of this research was to perform an integrated analysis of botanical, meteorological and chemical precipitation parameters so as to compare them in fragments of the riparian forest in the lower (São Leopoldo-SL) and upper (Caraá-CA) stretches of the Rio dos Sinos Hydrographic Basin (RSHB), RS, Brazil. Rainwater was chemically analyzed, the community structure of epiphytic ferns was surveyed and the ecological characterization was evaluated through the Rapid Habitat Assessment Protocol (RHAP). The results showed that the chemical composition of rainwater is influenced by the environment of each area. In the upper stretch (CA), for instance, the main contribution is that of marine ions, while in the lower stretch (SL), the most impacting aspects are urbanization and industrialization. Similarly, the results depict a reduction of richness and a simplification of the community structure of epiphytic ferns and their environmental quality according to the RHAP categories, towards the base level of the RSHB. The integrated analysis, in which different methods were applied, proved to be an efficient tool to evaluate environmental quality. This analysis considers that a greater number of biotic and abiotic variables may be applied in different scenarios. botânicos, meteorológicos e químicos da precipitação, a fim de compará-los em fragmentos de mata ciliar, nos trechos inferior (São Leopoldo-SL) e superior (Caraá-CA) da Bacia Hidrográfica do Rio dos Sinos (BHRS), RS Brasil. Para tal, foram realizadas análises químicas da água de chuva, analisada a estrutura comunitária das samambaias epifíticas e, avaliada a caracterização ecológica, através do Protocolo de Avaliação Rápida de Hábitats (PARH). Os resultados demonstraram que a composição química da água de chuva é influenciada pelo entorno de cada local estudado, sendo que do terço superior (CA), a maior contribuição é de íons de origem marinha, enquanto que, no trecho inferior (SL), a mesma é oriunda da urbanização e industrialização. Da mesma forma, ficou evidenciada a redução da riqueza e simplificação da estrutura comunitária de samambaias epifíticas e de sua qualidade ambiental de acordo com as categorias do PARH, em direção à foz da BHRS. A análise integrada aplicando diferentes métodos foi uma ferramenta eficiente para avaliar a sua qualidade ambiental, pois permite integrar um maior número de variáveis bióticas e abióticas, podendo ser aplicada em diferentes cenários.Palavras-chave: água de chuva, análise ambiental, caracterização ecológica, samambaias epifíticas.
