Abstract

Six anthocyanin pigment were isolated from Malvaviscous-arborea L. and five from Althea rosea cav. (Family: Malvaceae). The identification of these pigments was achieved by paper chromatography, acid and enzymatic hydrolysis and spectralanalysis. The study revealed the presence of cyanidin-3B-D-glycoxy-loside-5B-D-glucoside, cyanidin-3,5-B-D-diglucoside, Malvidin-3,5B-D-diglucoside, Malvidin-3-B-D-diglucoside, Delphinidin-3-B-D-glucoside and Pelargonidin-3-B-D-glactoside in the petals of Malvaviscous-arborea L. andcyanidin-3,7-B-D-diglucoside, cyaniding-3-B-D-glucoxyloside,Delphinidin-3-B-D-galactoside, petunidin-3-B-L-rhamnoside andpelargonidin-7-B-D-glucoside in the petals of Althea rosea cav.
