Abstract: The classical toxic effect produced by this Ipomoea fistulosa is due to the                  accumulation of oligosacharides in various tissues cell cytoplasm, mainly                   nervous, liver and lymphatic tissues, that leads to the cell vacuolitation.                  These effects are attributed to the presence of substances called                   swansonina and calisteginas in the vegetables, which produce inhibition                  of enzymes liposomales responsible for the metabolic carbohydrates.                   In natural conditions, the plant is not consumed by the animals. Its                  consumption occurs alone in determined times of year, for lack of                  sufficient pasture, and it is more frequent in young animals.                  Since standard literature does not register any data on the chemical                  analysis of the kind Ipomoea, we report here the results on the extraction,                  isolation and spectroscopic identification of the present alkaloids in this                  plant.     Keywords: Alkaloids – Ipomoea fistulosa – IR spectrum
