Phytochemical Profile Of Hydrostachys Insignis (Hydrostachyaceae), Ron Scogin
Phytochemical Profile Of Hydrostachys Insignis (Hydrostachyaceae), Ron Scogin
Aliso: A Journal of Systematic and Floristic Botany
Foliar material of Hydrostachys insignis contains kaempferol 3-glucoside and kaempferol 3-sophoroside. Iridoids, proanthocyanidins, acteoside, alkaloids, hydrolyzable tannins (ellagic acid), cyanogenic glycosides, and saponins could not be detected. This chemical profile does not support proposed relationships between Hydrostachyaceae and either Podostemaceae or members of the Scrophulariales. It is proposed that the chemical profile of Hydrostachyaceae reflects phylogeny, not convergence to an aquatic habitat; but the profile does not suggest any accurate systematic alignment of Hydrostachyaceae.
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.
Foliar Flavonoids Of Camellia Chrysantha (Theaceae), Rob Scogin
Foliar Flavonoids Of Camellia Chrysantha (Theaceae), Rob Scogin
Aliso: A Journal of Systematic and Floristic Botany
Foliar flavonoids of Camellia chrysantha consist of two flavone C-glycosides which have chromatographic and spectroscopic properties very similar to corymboside and isocorymboside. The lack of detectable foliar flavonol glycosides contrasts with their presence in flowers of this species and may be anomalous within the genus Camellia.
Floral Pigments Of The Yellow Camellia, Camellia Chrysantha (Theaceae), Ron Scogin
Floral Pigments Of The Yellow Camellia, Camellia Chrysantha (Theaceae), Ron Scogin
Aliso: A Journal of Systematic and Floristic Botany
Floral pigments of Camellia chrysantha consist of three flavonoids (quercimeritrin, rutin, and isoquercitrin) and two xanthophylls (neoxanthin and an unidentified xanthophyll). The transfer of yellow petal coloration from C. chrysantha to other Camellia species may be hampered by interspecific genetic incompatibilities and by the complexities of genetic regulation of biosynthesis of the pigments involved.
