Abstract

SANTOS, MÁRCIA DÉBORA DOS  and  BLATT, CECÍLIA TERUMI TERADAIRA. Teor de flavonóides e fenóis totais em folhas de Pyrostegia venusta Miers. de mata e de cerrado. Rev. bras. Bot. [online]. 1998, vol.21, n.2, pp. 135-140. ISSN 1806-9959.  http://dx.doi.org/10.1590/S0100-84041998000200004.

A quantitative analysis of the foliar flavonoids, total phenolics, and tannins of Pyrostegia venusta originating from the forest and cerrado were carried out to check the influence of these biocores in the production of these elements. The results for both flavonoids and phenolics revealed no significant differences between forest and cerrado, plants, this thus implying that the species does not present phenotipic plasticity based upon these characters, when considering soil differences of both places. Tannins were absent in the leaves of this plant.

Keywords : Flavonoids; total phenolics; tannins; Pyrostegia venusta.
