Ethnopharmacological Relevance: Bougainvillea xbuttiana is widely distributed in Mexico and it is used as an analgesic in folk medicine.
Aim Of The Study: In the present study the in vivo antinociceptive and anti-inflammatory effects of the Bougainvillea xbuttiana ethanolic extract have been studied in mice.
Materials And Methods: The phytochemical analysis was performed. Antinociceptive activity was evaluated through writhing and formalin test in mice. The anti-inflammatory activity was determined with the carrageenan-induced mice paw oedema model. IL-6, IL-10 and IFN-γ levels were determined by enzyme-like immunosorbent assay, whereas TNF and nitrite levels were detected by standard assay with L929 cells and colorimetric Griess reactive, respectively.
Results: The results showed that the ethanolic extract of the Bougainvillea xbuttiana has significant anti-inflammatory and antinociceptive activities, by inhibition of nociception induced by acetic acid and paw oedema. This extract also induced a decrease in TNF levels and an increase of IL-6, IFN-γ and NO levels that we observed up to 2h. The highest levels of IL-10 were observed up to 4h. The ratios of pro-/anti-inflammatory cytokines in sera from mice injected with the ethanolic extract, may be manifesting an anti-inflammatory status.
Conclusions: The present study provides convincing evidences that Bougainvillea xbuttiana extract possesses significant anti-nociceptive and anti-inflammatory effects.

Background: Different pharmacological properties, such as antioxidant, antiproliferative, and anti-inflammatory properties, have been described among natural products. We previously described that the (Variety Orange) ethanolic extract (BxbO) has an anti-inflammatory effect; however, this action is not fully understood. In this study, the action of the BxbO extract on the secretion of inflammatory mediators in two experimental models, and , after LPS challenge was evaluated.

Activation of macrophages may be one of the possible approaches in modulating inflammation. We previously reported that extract showed an immunomodulatory activity. Here we compare the activation of macrophages exposed to extract and compare it with the other treatments such as LPS, IL-4, and IL-10.

A full-length cDNA encoding ribosome-inactivating/antiviral protein from the leaves of Bougainvillea xbuttiana was recently isolated. The coding region of cDNA was cloned and expressed in Escherichia coli, and the protein product was designated as BBAP1 (Bougainvillea xbuttiana antiviral protein 1). BBAP1 showed ribonuclease activity against Torula yeast RNA.
