Isolation and characterization of starch from an unconventional source like turmeric rhizome indicate a potential application as a functional ingredient in foods and pharmaceutical industries including agglomerated products.

The isolated compounds namely 4-epicyclomusalenone, cycloeucalenol acetate and chlorogenic acid have demonstrated their antioxidant properties in different in vitro assay models. The present study indicated that the vast quantity of banana rhizome which was incinerated could be a potential source of natural antioxidant compounds. This can also be used in the food, nutraceutical and pharmaceutical industries.
