✦ Synopsis

Four new pyranoanthocyanins, namely pyranocyanin A and B and pyranodelphinin A and B, with the pyrano[4,3,2-de]-1-benzopyrylium core structure were isolated together with known cyanidin 3-rutinoside and delphinidin 3-glucoside from black currant seed and their chemical structures were elucidated by means of 2D NMR and ES-MS.
