Abstract |
The present work is part of the Agrocos EUFP7 project and aimed at identifying new promising plant species exhibiting agrochemical properties or cosmetic interest. French Guiana being one of the megadiverse area of the globe considering plant biodiversity, 300 plant parts from 64 families were collected for the project. Among the 600 extracts evaluated as antifungals against phytopathogens, insecticides against plant pests and herbicides, 10% revealed an interesting activity. 7 of these extracts, mostly from the Leguminosae family, are currently under investigation for isolation and evaluation of pure compounds. Concerning cosmetic activity, 8 extracts from 5 different families were selected for further study. These results may lead to the development of novel products headed to agrochemical and cosmetic industry. |

Abstract |
Psidium acutangulum Mart. ex DC is used exclusively by the Wayana Amerindians in French Guiana, more particularly for the treatment of malaria. To understand this specific use, we embarked upon evaluating the antimalarial and anti-inflammatory activities of this traditional remedy as prepared by the Amerindian users. The decoction exerted good antiplasmodial activity in vitro (IC50 4 µg/ml on P. falciparum FcB1) and in vivo (39.7% inhibition of P. berghei NK65 in the murine model at 2 × 150 µl/day), as well as a strong anti-inflammatory effect in vitro regarding IL-1β, IL-6 and IL-8. Fractionation of the ethyl acetate extract (IC50 < 1 µg/ml) led to the isolation of six pure compounds, two of them, guaijaverine and the new compound wayanine, being moderately active against P. falciparum FcB1 in vitro (IC50 5 – 7 µg/ml). Along with the absence of cytotoxicity of the decoction and pure compounds, these results support the traditional use of this plant. |
