Biological activity of Herissantia crispa (L.) Brizicky
Lima,Igara Oliveira; Costa,Vivian Bruna Machado; Matias,Wemerson Neves; Costa,Danielly Albuquerque da; Antas e Silva,Davi; Agra,Maria de FátimaThe crude methanol extract (EMeOH) of the aerial parts of Herissantia crispa (L.) Brizicky, plant riches in flavonoids and without pharmacological studies, was tested to value its activity under the behaviour parameters and to determine the lethal dose (LD50) in mice; antimicrobial and antiulcerogenic activities. The EMeOH (5,000 mg/kg, v.o. or 2,000 mg/kg i.p.) did not alter the behaviour parameters and there ...
