Abstract | | | | This study investigated the acute toxicity, phytochemical constituents and anti - ulcer properties of methanolic leaf extract of Annona muricata in mice. The anti - ulcer activity was evaluated using absolute ethanol-induced ulcer and aspirin-induced ulcer models in mice. An LD50 of 354.8 ± 8 mg/kg body weight, bw of the extract was obtained on oral administration.
