Resumen

[EN] Two new 3-deoxyanthocyanidins, 6,7,3 ,4 -tetrahydroxy-5-methoxyflavylium and 6,7,4 -trihydroxy-5- methoxyflavylium, and the pigment carajurin, which has been previously identified, were isolated from dried leaves of Arrabidaea chica, a creeper native to the American tropics. The structures of the components were elucidated by 1H- and 13C-NMR spectroscopy and HPLC-MS, including X-ray crystallographic analysis for carajurin.
