Previous issue date: 2017-03-31 / As ?rvores da esp?cie Copaifera multijuga Hayne crescem abundantemente na regi?o da Amaz?nia, apresentando grande visibilidade por seu ?leo-resina, que apresenta atividade anti-inflamat?ria. A forma??o de complexo de inclus?o (CI) com a ciclodextrina (CD) tem sido aplicada como alternativa para resolver algumas limita??es que os ?leos tem em comum, principalmente a baixa solubilidade em ambientes aquosos. Ent?o, o objetivo deste trabalho foi desenvolver CI?s do ?leo-resina de Copaifera multijuga (OCM) com a ?-ciclodextrina (?CD) e com a hidroxipropil-?-ciclodextrina (HP?CD) e avaliar a atividade anti-inflamat?ria deles. Inicialmente, foram realizados estudos te?ricos computacionais nos quais foram calculadas as energias de intera??o entre a ?CD e o ?-cariofileno (?CF), composto mais abundante do OCM. Em seguida, foram preparados os CI?s com ?CD e HP?CD pelos m?todos da mistura f?sica (MF), malaxagem (MAL) e co-precipita??o (CP). Foi realizada a caracteriza??o f?sico-qu?mica dos CI?s por espectroscopia de absor??o na regi?o do infravermelho com transformada Fourier (FTIR), microscopia eletr?nica de varredura (MEV), difra??o de raios X pelo m?todo do p? (DRX), an?lise termogravim?trica (TG) e calorimetria explorat?ria diferencial (DSC). Por fim, os CI?s de ?CD e HP?CD foram comparadas em rela??o ? suas atividades anti-inflamat?rias com o OCM puro. Os estudos te?ricos computacionais mostraram valores energ?ticos de -20,8 kcal?mol-1 e -17,0 kcal?mol-1 da complexa??o com a face menor e com a face maior do ?CF, respectivamente, entrando pela cavidade maior da ?CD. Pelo FTIR, foi poss?vel observar que ocorreu a intera??o entre a ?CD e o OCM por MAL e CP, e entre a HP?CD e o OCM, pelo CP. Na MEV, na DRX e na TG, foi poss?vel concluir que houve intera??o entre a ?CD e o OCM por MAL e CP. No caso da DSC foi observado que ocorreu intera??o entre a ?CD e o OCM e entre a HP?CD e o OCM pelos dois m?todos. O OCM e os CI?s de ?CD e de HP?CD (preparados por CP) mostraram evidente atividades anti-inflamat?rias pela diminui??o do edema de pata, nos n?veis de nitrito e da atividade da enzima mieloperoxidase, evidenciando que os CI?s do OCM com a ?CD e a HP?CD mantiveram a atividade anti-inflamat?ria do OCM. / Copaifera multijuga Hayne trees grows abundantly in Amazon region, presenting wide visibility for its oleoresin, which shows anti-inflammatory activity. The inclusion complex (IC) formation with cyclodextrin (CD) has been applied as alternative to solve some limitations that oils have in common, principally the poor aqueous solubility. Thus, this work aimed the ICs development of Copaifera multijuga oleoresin (CMO) with ?-cyclodextrin (?CD) and with hydroxypropyl-?-cyclodextrin (HP?CD) and evaluating of its anti-inflammatory activities. Initially, it were realized computational theoretical studies, in which were calculated the interaction energies between ?CD e o ?-caryophyllene (?CP), most abundant compound in CMO. Next, it were prepared ?CD and HP?CD IC?s by physical mixture, kneading method (KND) and slurry method (SL). ICs physical-chemical characterization was realized by Fourier transform infrared absorption region spectroscopy (FTIR), scanning electronic microscopy (SEM), powder X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Finally, ?CD and HP?CD IC?s were compared to pure CMO, in relation to its anti-inflammatory activity. Computational theoretical studies showed energetic values of -20.8 kcal?mol-1 and -17.0 kcal?mol-1 of complexation with ?CP minor and lager face, respectively, entering through the ?CD larger cavity side. In FTIR, it was possible observing that occurred interaction between ?CD and CMO by KND and SL, and between HP?CD and CMO by SL. In SEM, in XRD and in TGA, it was possible conclude that there was interaction between ?CD and CMO by KND and SL. In DSC case, it was observed that occurred interaction between ?CD and CMO and between HP?CD and CMO by KND and SL. CMO and ?CD and HP?CD ICs showed evident anti-inflammatory activity by paw edema, nitrite concentration and myeloperoxidase activity decreasing, evidencing that ICs of CMO with ?CD and HP?CD, which keeping the CMO anti-inflammatory activity.
