CARDOSO, Cláudia Andréa Lima; HONDA, Neli Kika  and  DIAS, Edna Scremin. Evaluation of the chromatographic profile of species of Polygonum and samples of the "erva-de-bicho". Rev. bras. farmacogn. [online]. 2006, vol.16, n.2, pp.236-245. ISSN 0102-695X.

The species Polygonum punctatum, Polygonum hydropiperoides, Polygonum ferrugineum, Polygonum acuminatum were analyzed and compared with commercialized samples of "erva-de-bicho". This analysis was performed using high performance liquid chromatography. It was verified that the analyzed samples show a distinct. The chromatographic profile of the samples commercialized as "erva-de-bicho" was similar to the Polygonum acuminatum or Polygonum ferrugineum profiles, or did not present peaks in the chromatograms. The chromatographic profiles were monitored in the 254 nm and 362 nm.

Keywords : Polygonum acuminatum; Polygonum ferrugineum; Polygonum hydropiperoides; Polygonum punctatum; high performance liquid chromatography.
