Abstract
The carotenoids of the flowers of 2 species of Tecoma, T. stans and T. capensis, have been investigated. Both species contain [beta]-carotene and zeaxanthin, while T. capensis contains in addition [gamma] -carotene, lycopene, a rubixanthin-like pigment and a trace of the colorless polyene phytofluene. The concentration of carotenoids in the red flowers of T. capensis and the yellow flowers of T. stans are 28.6 and 12.6 mg./l00 g. fresh weight respectively. The corresponding ratios of epiphasic to hypophasic pigments in the two species are 2.2:1 and 1:6.Keywords
