Abstract

Two novel 6-hydroxydelphinidin glycosides were isolated from the red-purple flowers of Alstroemeria ‘Westland’ along with ten known anthocyanins. These novel pigments were determined to be 6-hydroxydelphinidin 3-O-β-D-glucoside and 6-hydroxydelphinidin 3-O-[6-O-(malonyl)-β-D-glucoside] by spectral and chemical methods. The ten known pigments were also identified as cyanidin 3-glucoside, delphinidin 3-glucoside, 6-hydroxycyanidin 3-glucoside, cyanidin 3-rutinoside, delphinidin 3-rutinoside, 6-hydroxycyanidin 3-rutinoside, 6-hydroxydelphinidin 3-rutinoside, cyanidin 3-malonylglucoside, delphinidin 3-malonylglucoside, and 6-hydroxycyanidin 3-malonylglucoside, respectively.
