Annona tomentosa R.E.Fr is a species not endemic to Brazil that belongs to the phytogeographic areas of the Amazon, Cerrado and Pantanal. Popularly known as “araticum rasteiro” or “araticum de moita”, A. tomentosa is edible and tea made from the leaves has been used as an anti-inflammatory by native communities. There is no scientific evidence for these uses of A. tomentosa, especially those related to the control of pain and inflammation. For this reason, in the present study we evaluated the antinociceptive and anti-inflammatory activities of partitions from the methanolic extract of A. tomentosa leaves (A. tomentosa leaf methanolic extract (ATFM) in hexane partition: ATFM-H; ATFM in dichloromethane partition: ATFM-D; ATFM in ethyl acetate partition: ATFM-Ac; ATFM in butanol partition: ATFM-B) in mice.

The antinociceptive effects of leaf extracts from A. tomentosa were evaluated by …
