Potencial alelopático de catequinas de Tachigali myrmecophyla (leguminosae) Allelopathic potential of catechins of the Tachigali myrmecophyla (Leguminosae)

Abstract

Two compounds, (+)-catechin and epicatechin, were isolated from leaves of T. myrmecophyla, using chromatographic techniques. The structural identification was carried out on the basis of ¹H and 13C NMR spectral data and comparison with literature data. The compounds (+)-catechin and epicatechin were submitted to germination inhibition and radicle and hypocotyl growth assays. Results showed some significant activities confirming the initial hypothesis about allelopathic properties of that plant.
