The qualitative and quantitative composition of the essential oil from aerial parts of Eupatorium buniifolium Hooker et Arnott (Asteraceae) has been investigated for the first time. The essential oils were obtained by steam distillation of leaves and analysed by GC-MS; 44 components were identified. Monoterpene and sesquiterpene hydrocarbons, especially α-pinene (14.7%), β-elemene (12.2%), germacrene D (11.5%), trans-β-guaiene (6.5%) and (E)-caryophyllene (4.3%), were the major constituents found in the oils. The characterisation of E. buniifolium by enantioselective GC was performed by evaluation of the enantiomeric ratios of α-pinene, sabinene, β-pinene, limonene, terpinen-4-ol and germacrene D.

ABSTRACT.
Swainsonine-containing plants comprise a group of important poisonous plants in Brazil. This research aimed to characterize both the behavioral changes related to reproduction and appearance of lesions in the reproductive system of bucks poisoned by Ipomoea brasiliana. I. brasiliana plants were collected and administered at a dose of 4g/kg (800?g swainsonine/kg) to two groups of bucks for 45 days. Goats from Group I were euthanized on the 46th day of the experiment, and goats from Group II were euthanized on the 120th day. Group III was composed of goats that did not receive I. brasiliana and were euthanized on the 120th day of the experiment. Reproductive behavioral changes were observed starting on day 20 and were characterized by an absence of courtship behavior, and Flehmen reflex, decrease or loss of libido and inability to perform mating. After 120 days, Group II goats showed no regression of the changes in their reproductive behavior or improvement of their seminal parameters. The main defects observed in the sperm of goats that consumed I. brasiliana were cytoplasmatic droplets, bent tails and detached tails. The main histopathological findings were reported in tests, with cytoplasmic vacuolization of germline and Sertoli cells, generalized impairment of spermatogonia maturation with exfoliation of degenerative cells, cell fragments, rare abnormal spermatocytes in the seminiferous lumen and disappearance of Leydig cells. Results of this study confirmed the hypothesis that I. brasiliana causes testicular degeneration in male goats.

RESUMO.
Este trabalho teve como objetivo caracterizar as mudanças comportamentais relacionadas a reprodução e lesões no sistema reprodutor de caprinos intoxicados por Ipomoea brasiliana. A planta foi coletada e administrada na dose de 4g/kg (800?g swainsonina/kg) para dois grupos de caprinos durante 45 dias. Os caprinos do Grupo I foram eutanasiados no 46º dia do experimento e os caprinos do Grupo II no 120º dia. O Grupo III foi constituído por caprinos que não receberam I. brasiliana e foram eutanasiados no 120º dia de experimento. Alterações comportamentais reprodutivas foram observadas a partir de 20 dias de experimento e consistiram em ausência do comportamento de corte, ausência de reflexo de Flehmen, diminuição ou perda de libido e incapacidade de realizar a monta natural. Após 120 dias, os caprinos do Grupo II não apresentaram regressão de alterações reprodutivas. Os principais defeitos observados no sêmen dos caprinos que consumiam I. brasiliana foram gotas citoplasmáticas, caudas dobradas e caudas destacadas. Os principais achados histopatológicos consistiram em vacuolização citoplasmática das células da linhagem germinativa e células de Sertoli; comprometimento generalizado da maturação das espermatogônias com esfoliação de células degeneradas; presença de fragmentos celulares e raros espermatócitos anormais no lúmen dos túbulos seminíferos e ausência de células de Leydig. Os resultados confirmam a hipótese de que o consumo de I. brasiliana causa degeneração testicular em caprinos. MenosABSTRACT.
