RT Journal Article SR Electronic T1 Flavonoid Distribution in Gleditsia JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 14 OP 18 DO 10.48044/jauf.1977.004 VO 3 IS 1 A1 Frank S. Santamour, Jr. YR 1977 UL http://auf.isa-arbor.com/content/3/1/14.abstract AB The major flavonoids of the leaves of Gleditsia species are flavone C-glycosides, with sufficient interspecific differences in distribution to allow for the identification of certain species. G. triacanthos was readily distinguished from all other species by high concentrations of leucocyanidin and two catechins. The involvement of G. triacanthos in the parentage of G. x texana and the verification of an artificial hybrid of G. triacanthos were determined by chromatographic analyses and identification of the compounds peculiar to G. triacanthos.
