The species Annona nutans (R. E. Fries) is a plant found in Bolivia, Paraguay, Argentina and the Brazilian cerrado. Considering the anti-inflammatory and antinociceptive activities of the hydrometanolic fraction (FHMeOH) of A. nutans leaves previously reported, the present study aimed to evaluate in vivo anti-inflammatory and antinociceptive activities of a subfraction obtained from FHMeOH, the butanolic fraction (FBuOHf). Intraperitoneal (i.p.) treatment with FBuOHf (50 and 100 mg · kg-1) inhibited paw edema induced by carrageenan. Moreover, FBuOHf (100 mg · kg-1, i.p.) also suppressed polymorphonuclear (PMN) leukocyte migration in the footpad. Regarding the antinociceptive activity, FBuOHf (50, 100, and 200 mg · kg-1, i.p.) inhibited acetic acid-induced abdominal writhing. In the formalin test, this fraction (200 mg · kg-1, i.p.) reduced licking time only in the inflammatory phase. The FBuOHf contents flavonoids and cinnamic acid derivatives, such as quercetin-3-O-galactoside, quercetin-3-O-glucoside, isorhamnetin-3-O-galactoside, quercetin-3-O-ß-D-apio-furanosyl-(1â2)-galactopyranoside and chlorogenic acid, identified and quantified by LC-MS. The FBuOHf possesses anti-inflammatory and peripheral antinociceptive activities.
