摘要: The composition of three samples essential oil (EO) extracted from the leaves and flowers Hyptis fruticosa (Lamiaceae) were investigated by GC/MS GC-FID. variability constituents biological activity evaluated in samples. Acetic acid-induced abdominal constrictions formalin-induced pain tests mice used for screening antinociceptive activity. possible antagonism oils or morphine (MOR) effects pretreatment with naloxone, showed no influence on action acetic writhing test. All examined presented sample obtained collected during vegetative growth stage, near Sao Cristovao at Sitio Tujubeba exhibited highest effect. same had a main percentage 1,8-cineole (18.70%). Nevertheless, location, significant difference (p < 0.05) response intensity first phase paw licking (100 mg/kg) possibly due to higher contents α-pinene (20.51%) β-pinene (13.64%). results provide evidence use H. traditional medicine practitioners management pain.
