This study describes the in vitro anthelmintic activity of aqueous extracts (AE), ethyl acetate extracts (EE), flavonoid fractions (FF) and saponin fractions (SF) obtained from sisal waste (Agave sisalana) against gastrointestinal nematodes of goats. The activity of these extracts was evaluated by performing inhibition of egg hatch (EHA) and larval(More)
BACKGROUND The effect of the extraction time (min) and temperature (°C) on the yield of betulinic acid (BA) from Zizyphus joazeiro barks using focused microwave-assisted extraction was investigated. MATERIALS AND METHODS The ethyl acetate was used as extractor solvent because it was shown to provide a betulinic acid-clean extract. A full two-level(More)
