Physicochemical/photophysical characterization and angiogenic properties of Curcuma longa essential oil

This study analyzed the physicochemical and photophysical properties of essential oil of Curcuma longa and its angiogenic potential. The results showed that curcumin is the main fluorescent component present in the oil, although the amount is relatively small. The experimental chorioallantoic membrane model was used to evaluate angiogenic activity, showing a significant increase in the vascular network of Curcuma longa and positive control groups when compared to the neutral and inhibitor controls (P 0.05). Histological analysis showed extensive neovascularization, hyperemia and inflammation in the positive control group and Curcuma longa when compared to other controls (P 0,05). A análise histológica mostrou maior neovascularização, hiperemia e elementos inflamatórios nos grupos controle positivo e Curcuma longa quando comparado aos demais grupos controles (P
