Evolution of flavonoids in the phaseolinae
Twenty South American Phaseolinae species were screened for flavonoids including eight species of Vigna: V. luteola, V. adenantha, V. candida, V. longifolia, V. lasiocarpa, V. caracalla, V. hookeri and V. peduncularis; three Phaseolus species: P. vulgaris var. aborigineus, P. lunatus and P. augustii...

| Sumario: | Twenty South American Phaseolinae species were screened for flavonoids including eight species of Vigna: V. luteola, V. adenantha, V. candida, V. longifolia, V. lasiocarpa, V. caracalla, V. hookeri and V. peduncularis; three Phaseolus species: P. vulgaris var. aborigineus, P. lunatus and P. augustii; eight Macroptilium species: M. fraternum, M. psammodes, M. prostratum, M. panduratum, M. longepedunculatum, M. bracteatum, M. erythroloma and M. lathyroides and Dolichopsis paraguariensis were examined. The majority of the isolated compounds (70%) were flavonol O-glycosides, mainly of quercetin (40%) and kaempferol (24%). Only one myricetin glycoside was detected with the more primitive trihydroxylated B-ring. The chemical profiles of these Phaseolinae species correspond to an intermediate evolutionary level according to the parameters of Harborne and appear to be relatively advanced in relation to the other members of the subfamily Papilionoideae. © 1994. |
