Punica granatum is from the family Punicacea. It
grows in all warm countries of the world and was
originally a native of Persia (Goodarzian and
Ekrami,2010). The rind of pomegranate contains a
considerable amount of tannin, about 19% with
pelletierine (Adeel et al., 2009; Tiwari et al.,2010).
The main coloring agent in the pomegranate peel is
granatonine which is present in the alkaloid form Nmethyl
granatonine (Goodarzian and Ekrami, 2010).
This compound gives colour to the dye. Its study will
enable us to understand the structural chemistry of
the coloring compound.
