“…Moutabea (mainly M. guianensis Aubl.) and other genera of Polygalaceae are an important source of xanthones (Ripardo Filho, et al, 2005;2014). These organic compounds are widely used as an insecticide, ovicide, and larvicide, as well as in the preparation of xanthydrol, which is used to determine urea levels in the blood (Williams, et al, 2000).…”

Se describe e ilustra la especie Moutabea chartacea, de los bosques húmedos de tierras bajas de Brasil (estado Amazonas), Venezuela (estados Amazonas, Bolívar y Delta Amacuro) y Colombia (departamentos de Caquetá, Meta y Vaupés), y se discuten sus relaciones morfológicas con su especie afín. Esta nueva especie es similar a M. gentryi, sin embargo, difiere por poseer los pecíolos, hojas, lóbulos de cáliz, frutos y semillas más pequeños, así como brácteas triangulares, pétalos con los ápices no reflexos y semillas densamente cubiertas por tricomas estrellados. Se incluye una clave actualizada de las especies de Moutabea. © 2018. Acad. Colomb. Cienc. Ex. Fis. Nat.

“…Moutabea guianensis is an Amazonian species that belongs to the family Polygalaceae, commonly known as cipó gogó de guariba [5]. Xanthones [6], coumarins [7], triterpenoids [8,9] steroids [10], flavonoids [11], pyrones [12,13] and xanthones [14,15] have been isolated from the species of the family Polygalaceae. In this study, from the roots of M. guianensis were isolated two compounds, the phenylpropanoid derivative methyl caffeate (1) and the coumarin scopoletin (2).…”

This study aimed establish the variations in the phytotoxic activity of hexane, ethyl acetate and methanol extracts of Moutabea guianensis, and methyl caffeate and scopoletin isolated from the ethyl acetate extract, variyng the concentration and the receptor species. Phytotoxic activity bioassays of germination (at 25 °C and 12 hours of photoperiod) and development of radicle and hypocotyl (25 °C and 24 hours of photoperiod) were developed. The seed germination of Mimosa pudica was sensitive to the roots hexane, ethyl acetate and methanol extracts at 1% (w/v), with inhibition potentials in 92%, 100% and 100%, respectively. Comparative analysis on the phytotoxic activity of the tested compounds revealed that scopoletin showed a higher inhibition potential on the seed germination bioassay against Mimosa pudica. Senna obtusifolia was not sensitive to the tested compounds. Methyl caffeate showed the highest potential to inhibit the development of radicle and hypocotyls, and the intensity of the allelopathic effects varied with the concentrations.
