Abstract

Objective: To study total phenolic content and antioxidant properties of 80% methanol extracts of ten high yielding rice varieties, five each from two different seasons namely aman and boro of Bangladesh. Methods: Total phenolic content was measured by Folin-Ciocalteau method while 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, hydroxyl ion scavenging, ferric reducing antioxidant power (Ferric reducing antioxidant power), and total antioxidant capacity (TAC) by ammonium molybdate, were used to analyze their Antioxidant properties. Results: Rice variaty BR5 of aman and BRRI dhan28 of boro season comparatively showed higher TPC and Antioxidant properties than the other rice varieties. BR22 of aman season showed the highest hydroxyl ion scavenging activity although it displayed the lowest TPC. Except for hydroxyl ion scavenging activity, aman rice varieties displayed comparatively higher total phenolic content and antioxidant property than the boro rice varieties. Conclusions: The results of the present study implies that the selected rice varieties possess moderate antioxidant capacity and therefore, can be considered as health supplements and nutraceuticals foods as rice is the staple food of Bangladesh.
