Última Pequi leaves incorporated into the soil reduce the initial growth of cultivated, invasive and native species Anais da ABC (AABC) ALLEM,LAÍSA N.; GOMES,ANABELE S.; BORGHETTI,FABIAN. Studies have identified the phytotoxicity of many native species of the Cerrado; however, most of them were conducted either in inert substrates, or using exaggerate proportions of plant material. We investigated the phytotoxicity of pequi leaves added to substrate soil in quantities compatible with the litter produced by this species. Pequi leaves were triturated and added to red latosol in concentrations of 0.75%, 1.5% and 3%; the control was constituted of leafless soil. These mixtures were added to pots and irrigated daily to keep them moist. Germinated seeds of the cultivated sorghum and sesame, of the invasive brachiaria and of the native purple ipê, were disposed in the pots to grow for five to seven days at 30°C within a photoperiod of 12 h....

(Lamiales, Bignoniaceae) extract in Wistar rats Genet. Mol. Biol. Lemos,Odilon A.; Sanches,Júlio C.M.; Silva,Ícaro E.F.; Silva,Márcio L.A.; Vinhólis,Adriana H.C.; Felix,Mireille A.P.; Santos,Raquel A.; Cecchi,Andréa O.. Tabebuia sp. is native to tropical rain forests throughout Central and South America. Although the biological and pharmacological effects of bark extracts have been intensely studied, little is known on the extract obtained from the flower. Herein, the genotoxic potential of a flower extract from T. impetiginosa ("ipê roxo") on the blood and liver cells of Wistar rats was evaluated. Experimental procedures involved only male animals. Graduated concentrations of the extract, viz., 100, 300 and 500 mg kg-1 of body weight, were gavage-administered and 24 h latter cells were collected and processed for analysis. With the exception of the 100 mg kg-1 dose, a significant increase in DNA damage was noted, when compared with a negative control group. Although the...
