No que diz respeito aos frutos de H. speciosa, a etnobot?nica indica o uso principalmente para o tratamento de inflama??o e tuberculose, entretanto n?o h? relatos de estudos que comprovem sua poss?vel atividade biol?gica. O estudo tem como objetivo avaliar a atividade antiinflamat?ria do extrato aquoso dos frutos de H. speciosa Gomes. O extrato aquoso foi preparado por decoc??o, posteriormente submetido a um fracionamento por meio de parti??o l?quido-l?quido e os metabolitos secund?rios identificados por Cromatografia l?quida de alta efici?ncia acoplada ao detector de arranjos de diodos (CLAE-DAD) e Cromatografia l?quida acoplada ao detector de arranjo de diodo e ao espectr?metro de massa (CLDAD-EM). As propriedades anti-inflamat?rias do extrato aquoso, fra??es diclorometano (CH2Cl2), acetato de etila (AcOEt) e n-butanol (n-BuOH), bem como a rutina e o ?cido clorog?nico foram investigadas usando modelos in vivo e in vitro. Testes in vivo compreenderam edema de orelha induzido por xilol, onde foi mensurado a forma??o do edema; peritonite induzida por carragenina onde foi avaliado os leuc?citos totais em 4h e bolsa de ar induzida por zimosam que foi mensurado a contagem total de leuc?citos e contagem diferencial em 6, 24 e 48 horas. Os testes in vitro avaliaram os n?veis de citocinas IL-1?, IL-6, IL- 12 e TNF-? usando ELISA a partir do modelo de peritonite induzido por carragenina. Os resultados demonstraram a presen?a de rutina e ?cido clorog?nico no extrato aquoso dos frutos de H. speciosa por CLAE-DAD e CLDAD-EM. O extrato aquoso e fra??es, bem como a rutina e ?cido clorog?nico inibiram significativamente o edema de orelha induzido por xilol e reduziram a migra??o celular em modelos animais, tanto na peritonite induzida por carragenina como na bolsa de ar induzida por zimosam. Al?m disso, foi observada a redu??o dos n?veis de express?o de citocinas IL-1?, IL-6, IL-12 e TNF-?. Este ? o primeiro estudo que demonstra o efeito anti-inflamat?rio do extrato aquoso dos frutos de Hancornia speciosa contra diferentes agentes inflamat?rios em modelos animais, sugerindo que suas mol?culas bioativas, especialmente rutina e ?cido clorog?nico contribuem, em parte, para o efeito anti-inflamat?rio do extrato aquoso. Estes resultados suportam a utiliza??o de H. speciosa na medicina popular e revelam que o extrato aquoso apresenta um potencial terap?utico para o desenvolvimento de uma droga herbal com propriedades anti-inflamat?rias. / Hancornia speciosa Gomes (Apocynaceae), popularly known as ?mangabeira?, has been used in folk medicine to treat inflammatory disorders, hypertension, dermatitis, diabetes, liver diseases and stomach disorders. Regarding the Hancornia speciosa fruits, the ethnobotany indicates its use especially for treating inflammation and tuberculosis. However, no study has been done so far to prove such biological activities. The objective was evaluation anti-inflammatory activity from the fruits of Hancornia speciosa Gomes (mangabeira). Aqueous extract was prepared by decoction, subsequently submitted the liquid-liquid fractionation. The secondary metabolites were identified by high performance liquid chromatography coupled with detector diode array (HPLC-DAD) and liquid chromatography diode array detector coupled with mass spectrometry (LC-DAD-MS). The anti-inflammatory properties of the aqueous extract, dichloromethane (CH2Cl2), ethyl acetate (EtOAc) and n-butanol (n-BuOH) fractions of the fruits from H. speciosa, as well as rutin and chlorogenic acid were investigated using in vitro and in vivo models. In vivo tests comprised the xylene-induced ear edema that was measured the formation of edema, carrageenan-induced peritonitis was evaluated the total leukocytes at 4h and zymosan-induced air pouch was measured the total leukocytes and differential cell count at 6, 24 and 48 hours, whereas in vitro tests were evaluated levels of cytokines IL-1?, IL-6, IL-12 and TNF-? using ELISA obtained of carrageenan-induced peritonitis model. The results showed the presence of rutin and chlorogenic acid were detected in the aqueous extract from H. speciosa fruits by HPLC-DAD and LC-DAD-ME. Furthermore, the aqueous extracts and fractions, as well as rutin and chlorogenic acid significantly inhibited the xilol-induced ear edema and reduced cell migration in the animal models such as carrageenan-induced peritonitis and zymosan-induced air pouch. In addition, reduced levels of cytokines IL-1?, IL-6, IL-12 and TNF-? were observed. This is the first study that demonstrated the anti-inflammatory effect of aqueous extract from Hancornia speciosa fruits against different inflammatory agents in animal models, suggesting that their bioactive molecules, especially rutin and chlorogenic acid contributing, at least in part, to the anti-inflammatory effect of aqueous extract. These findings support the widespread use of Hancornia speciosa in popular medicine and demonstrate that this aqueous extract has therapeutic potential for the development of a herbal drugs with anti-inflammatory properties.
