A study of the flavonoids of the Potentilla pensylvanica complex in North America

Abstract

The major flavonoid complement of leaves of the polyploid series Potentilla finitima Kohli & Packer (2n = 14), P. pensylvanica L. (2n = 28), and P. bipinnatifida Hook. (2n = 56) has been determined. Eleven flavonoid glycosides have been identified and their distribution within the polyploid series plotted and discussed. Evidence is presented for the occurrence of a 'recombinant' flavonoid in the species P. pensylvanica L.

Studies on Argemone. II. Impact of polyploidy and hybridity on some plant metabolites.

“…3, 16 and 32 characterise the profiles of the hybrid taxon. These results are similar to those obtained by Alston and Turner (1962) in Baptisia, Iiyama and Grant (1972) in Avena, Murray and Williams (1973) in Briza media, and Kohli and Denford (1977) in Potentilla. Origin of new compounds through hybridity can be explained on the basis of new gene combinations leading to novel expression.…”

Flavonoid studies in four species of the Oxytropis campestris complex (Fabaceae–Galegeae)

“…In some previous studies of polyploid complexes (Kohli and Denford 1977;Wolf et al 1979) the component taxa were very similar in their flavonoid composition. Only 0 .…”
