Abstract

Three anthocyanins, the 3-galactoside of delphinidin (1) (8.5 %), petunidin (2) (9.2 %) and malvidin (3) (73.8 %) were isolated from the deep red-purple flowers of Abrus canescensby a combination of chromatographic techniques. Their structures were elucidated by on-line diode array detection chromatography and homo- and hetero-nuclear magnetic resonance (NMR) techniques.

 

Key words: Abrus canescens, Fabaceae, anthocyanin, malvidin 3-galactoside, petunidin 3-galactoside, delphinidin 3-galactoside, taxonomy.
