Leishmanicidal galloylquinic acids were isolated from the ethyl acetate extract of Byrsonima coccolobifolia. These phenols and gallic acid showed to be a new class of potent noncompetitive inhibitors of arginase ARG (K-i ranging from 0.10 to 0.68 mu mol L-1) from Leishmania amazonensis. Quinic acid did not exhibit significant inhibition of ARG, ind...

Microalgae are considered promising organisms with applications in several areas, among them CO2 fixation, food industry, cosmetics and pharmaceuticals. Industrialization in the production of such organisms will generate algae residues that may be used for production cost reduction. In this research we proposed the use of microalgae as cement mater...

This study evaluated the allelopathic potential of leaf and root extracts of Lafoensia glyptocarpa Koehne on seed germination and the growth of seedlings and sesame (Sesamum indicum L.) metaxylem cells.

Byrsonima coccolobifolia leaf and stem extracts were studied in the search for possible leishmanicidal compounds using arginase (ARG) from Leishmania amazonensis as a molecular target. Flavonoids 1b, 1e-1g, 2a, 2b, and 2d-2f showed significant inhibitory activity, with IC50 values ranging from 0.9 to 4.8 μM. The kinetics of the most active compound...

We surveyed a Cerrado and Riparian Forest vegetation area located at São Carlos Federal University (21°58’ S, 47°51’ W). The objective of the survey was to provide a full inventory of the area’s angiosperm flora. This inventory was conducted in a region in which few remnants of Cerrado and Riparian Forest are left because of the destruction of thes...

Artificial sandbar opening of intermittently open estuaries is a practice utilised worldwide to improve water quality, fishing, and recreational amenities and to prevent the flooding of adjacent properties. Breaching causes the water level to drop drastically, exposing plants to two water level extremes. With some exceptions, estuarine communities...

Beauv (Poaceae), Ipomoea grandifolia (Dammer) O'Donell (Convolvulaceae) and Euphorbia heterophylla L. (Euphorbiaceae)). The experimental design was entirely randomized, with six replicates. The target plant...

The Massaguaçu River estuary is an irregular estuary with sandbar breaching cycles that are irregular and happen several times each year. The species Ludwigia octovalvis is a perennial weed in several places around the world, but it is seasonal in the Massaguaçu River. In this survey we determined the relationship between the rain, estuary water le...

A new species of Pelexia Poit. ex Lindl. (Orchidaceae, Spiranthinae) occurring in central São Paulo, southeastern Brazil, is described and illustrated as P. vinosa A. W. C. Ferreira, M. I. S. Lima & Pansarin. Pelexia vinosa is recognized by its leaves that are present at flowering and its dark purple leaf blades with reddish margins. Inflorescences...

Crop weeds are the main problem in agriculture, causing a worldwide annual loss of about US$95 billion. The principal method for control is the use of synthetic herbicides. The continued use of these products increases crop costs, reduces crop quality, and leaves toxic residues in the environment, which are a threat to human and livestock health. T...

Estuaries are the buffer zones between river and ocean. Because they are under strong tidal influence, their flora must be able to cope with salinity and flooding stress. In the present study we combined results from two surveys we performed in the Massaguaçu River Estuary (23°37’20” S, 54°21’25” W), with the objective of providing a full inventory...

Identification of species with allelopathic potential has been a target of researches aiming to use them to control crop weeds. Ipomoea cairica is considered a weed with allelopathic potential, which has already been reported. The goal of this study was to evaluate the allelopathic properties of leaf extracts from Ipomoea cairica on the germination...

O uso prolongado torna os herbicidas tradicionais cada vez menos eficientes no combate às plantas daninhas. O uso de substâncias naturais extraídas das plantas é uma alternativa eficiente e menos agressiva ao meio ambiente. Os aleloquímicos de muitas espécies são possíveis matérias primas para o desenvolvimento de herbicidas orgânicos. Um dos princ...

Aquatic macrophytes represent one of the most productive communities and through metabolic activity are capable of producing great interference in the environment. Allelopathic interactions are apparently increased under biotic and abiotic stress and may exist in estuaries due to competition, salinity variation and other factors. The aim of this st...

A. glabra is a wetland species, occurring in dense populations. This behavior may indicate strong competition with other species or the existence of an allelopathic process involved in this distribution. In this study, we aim to: a) evaluate the allelopathic potential of extracts produced by A. glabra leaves on germination and seedling growth of ot...

Baptistonia pubes is an epiphyte that grows in Brazilian Atlantic Forest, in Paraguay and northern Argentina. It is considered vulnerable and threatened with extinction. Our aim was to verify seed germination efficiency and growth at two pHs, using two culture mediums: Murashige-Skoog (modified - (MS)) and banana pulp with added NPK 20-20-20 (Plant...

A map of the native vegetation remaining in São Carlos County was built based on aerial images, satellite images, and field observations, and a projection of the probable original vegetation was made by checking it against soil and relief surveys. The existing vegetation is very fragmented and improverished, consisting predominantly of cerrados (sa...

INTRODUÇÃO As zonas de fronteira entre ambientes aquáticos e o meio terrestre são denominadas ecótonos lênticos. As comunidades terrestres desses ecótonos, como mata ciliares, são chamadas de comunidades ripárias. Suas características são moldadas por muitos fatores e, dentre todos, as relações hidrológicas são os mais importantes. Em outras palavr...
