Abstract

LIMA, Ricardo Jorge Cruz et al. Hydrolyzable tannins in Bixa Orellana L.. Quím. Nova [online]. 2006, vol.29, n.3, pp. 507-509. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422006000300019.

The aqueous material found in the fruits of Bixa Orellana L. was collected, dried, and characterized using several experimental techniques, namely phytochemical analysis in order to identify the biologically active constituents, Fourier transform infrared (FT-IR) spectroscopy for vibrational analysis, and X-ray powder diffraction in order to identify the presence of crystalline phases in the sample. The results showed that the aqueous material possesses high concentrations of hydrolyzable tannin. This result justifies the anti-inflammatory activity of this substance reported in other studies.
