ABSTRACT
The aim of this study was to evaluate possible effects of pods from bordão-de-velho (Samanea tubulosa benth) extract on the reproduction of female rats.The extract was prepared by maceration wtith ethanol of dried and crushed pods, then it was concentrated in rotary evaporator. The pregnant Wistar rats were treated with a dose of 75 mg.100 g-1of body weight of Samanea tubulosa extract, by gavage , whereas the control group received 1ml.100g-1of saline by the same route for 19 days. After the euthanasia of the animals at day 20th,the following variables were analyzed: fetal body weight, weight of fetuses and placentas, number of corpora lutea, resorption points, live and dead fetuses and number of embryonic implantations. The extract from S. tubulosa pods, at the dose studied, showed toxicity causing fetal abnormalities, fetal resorption and pronounced decrease in the weight of offspring at birth. On the other hand, , the treatment with extract of S. tubulosa pods had no influence over corpora lutea and implantation numbers.
