Flavonoids of 11 samples of Cercis, comprising seven species, were isolated and identified. Only 3-O-monoglycosides of kaempferol, quercetin and myricetin were obtained. Bauhinia (the largest genus in tribe Cercideae) is akin to Cercis because flavones are rarely found in the former. On the other hand, species of Bauhinia often present glycosides of isorhamnetin and a wider diversity of glycosides, and only rarely present myricetin. The frequent occurrence of this flavonol and the simpler flavonoid profile of Cercis may reflect a greater antiquity of Cercis as compared with Bauhinia. With the exception of C. canadensis var. mexicana, Cercis taxa from xerophytic habitats did not yield kaempferol glycosides in detectable amounts, as opposed to taxa from mesophytic habitats. The results obtained are consistent with proposals of merging C. reniformis into synonymy of C. occidentalis, as well as the recognition of two North American species, C. canadensis and C. occidentalis, and the recognition of the Asian C. gigantea.
