Abstract

RABELO, D.S.; PAULA, J.R.  and  BARA, M.T.F.. Quantification of total phenols present in the bark of Trichilia catigua A. Juss (Meliaceae). Rev. bras. plantas med. [online]. 2013, vol.15, n.2, pp.230-236. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722013000200010.

Trichilia catigua A. Juss. is a medicinal plant used especially as a stimulant, possibly due to the presence of phenols. Among the methods used for the determination of polyphenols in raw plant materials is analysis through spectrophotometric assays since they have good sensitivity, are simple and more affordable. This study aimed to validate the analytical methodology for the determination of polyphenols in the bark of powder "catuaba". The method of Hagerman & Butler was employed in the quantification of total polyphenols, yielding 7.96%. The validated method has proven to be simple, rapid, selective, linear, accurate, precise and robust to be performed in the routine of a laboratory of quality control, constituting a possibility for the analysis of this medicinal plant.

Keywords : Trichillia catigua; medicinal plant; quality control; validation.
