Follar Flavonoids Of Keckiella Ternata, Ron Scogin
Follar Flavonoids Of Keckiella Ternata, Ron Scogin
Aliso: A Journal of Systematic and Floristic Botany
The major foliar phenolics of Keckiella ternata are quercetin 3-O-glucoside, kaempferol 3-O-glucoside, and acteoside (= orobanchin). The occurrence of flavonols in K. ternata is anomalous compared with other species of Keckiella and Penstemon, in which leaf flavonoids are based on luteolin and 6-hydroxyluteolin. The occurrence of foliar flavonols in K. ternata is interpreted as an advanced, derived condition.
