Acylated anthocyanins in the Commelinaceae were distinguished from other substances by high-performance liquid chromatography (HPLC) with concurrent three-dimensional photodiodearray detection (250-700nm), and four new acylated anthocyanins were isolated by preparative HPLC. According to the fast atom bombardment mass spectral (FABMS) analysis, alkalinehydrolysis and the absorbance ratio between λmax of around 320 nm and that around 500 nm, the new pigments were characterized as follows: zebrinin [MW (as flavylium ion) 1553, caffeic acid × 4] from Zebrina pendula, monodecaffeylzebrinin [MW 1391, caffeic acid × 3] from Zebrina pendula; rhoeonin [MW 1433, ferulic acid × 3] from Rhoeo spathacea; and setcreasin [MW 1609, ferulic acid × 4] from Setcreasea purpurea.
