Survey of vegetative flavonoids of Sedum section Gormania (Crassulaceae)

Abstract
The flavonoids in the leaves and stems of the 12 taxa of Sedum section Gormania were determined. Two of the three compounds occur in all 12 taxa. These two are 3,7-disubstituted kaempferol and laricytrin. The third compound, a highly methylated flavone, shows variation in its occurrence, and its presence or absence serves to substantiate two evolutionary groups of taxa in section Gormania.
