Comparative study of proximate composition and total antioxidant activity in leaves and seeds of Oryza sativa and Myriostachya wightiana.

The world largest and most prominent cereal crop with agricultural and economic importance as a staple food for more than 50% population worldwide is Rice. Myriostachya wightiana, belongs to the family Poaceae, is a perennial grass grows in inter‐tidal mangrove swamps. The current investigation was undertaken to evaluate and compare the Chlorophyll, Proximate composition and total Antioxidant potential of leaves and seeds of Oryza sativa and Myriostachya wightiana. Specific extraction and estimation methods were used to quantify the proximate composition. The results analysed with Student?s f-test for paired data and ?p? value less than 0.05 was considered as significant difference. Maximum chlorophyll content was observed in leaves of Oryza sativa (23.87 mg/gm). Superior amounts of starch, reducing and non reducing were found in seeds of Oryza sativa. While the better protein content was found in the leaves and seeds of Myriostachya wightiana. When compared with Oryza sativa, low quantity of lipid was found in seeds of Myriostachya. Elevated free proline was found in the leaves and seeds of Oryza and Myriostachya. The total antioxidant potential was found high in leaves and seeds of Myriostachya. The nutritive value of rice and Myriostachya seeds were quantified as 313.6 and 282.5 K.Cal/100gm correspondingly.
