“…The less efficient ananai concentration was 0.15 g/ml, which presumed that lower concentration did not induce abortifacient effects: LASZLO & HENSHAW (1954) cited the presence of a substance in un ripe Ananas comosus and Ananas sativus juices, that oMnking fresh or tak-(PATON, 1968; EARNS WORTH et al, ing raw, would interfere on the implan-1975). Those substances could have estation or in development of the pregnancy trogenic activity (FEURT & FOX, 1955) and/or stimulate uterine tissue either in vitro or in vivo, through the amine, 5-hydroxytryptamine (FARNSWORTH et al, 1975) and/or having an ecbolic ac tivity through the bromelain, proteolytic enzyme from the pineapple plant (NAKAMSHI & AOYAMA, 1980).…”

-The tea made from the infrutescense (corresponding to the edible part plus its cover) of ananai (Ananas ananassoides BAK.) was administered to pregnant rats, during the period of embryos implantation (5th -6th day through pregnancy). The animals were slaughtered on the 14th -15th day through the pregnancy and average rates of implantation and resorption were stimated.The results showed that this plant has an effective abortifacient effect, showing a strong inhibitory action on the implantation and/or post-implantation as well as a teratogenic effect, being more efficient in the concentration of 0,60 g/ml (P< 0.001).Key words: abortifacient, reproduction control, ananai, rats. Efeitos abortivos de Ananas ananassoides BAK. (Ananai) em ratos. RESUMO -O chá da infrutescência (frutículo mais a casca) do ananai (Ananas ananassoides)foi administrado em ratas grávidas, no período de implantação dos embriões (5 o -6 o dia de gestação). Os animais foram sacrificados no 14° -15° dia de gestação e a média de implantes e reabsorções foi avaliada. Verificou-se que esta planta tem efeito abortivo, produzindo importante efeito inibitòrio na implantação e/ou pós-implantação e efeito teratogênico, principalmente a partir da concentração 0,60 g/ml (P< 0.001).
