Gossypetin-7-glucoside, 8-glucoside, cyanidin-3,5-diglucoside and cyaniding-3(2´-glucosyl-rutnoside); delphinidin-3-sambubioside (canabinin), delphinidin-3-glucoside (myrtillin), cyaniding-3-sambubioside and cyanidin-3-glucoside have also been isolated from the plant (Rastogi & Mehrotra, 1990 & 93).
