The aim of the present study was to obtain comparative data on chemical compositions and nutritive values of four different varieties of rice. The results indicated that moisture, ash, total soluble solid and crude fiber contents of the different varieties of rice were in the ranges of 9.98-10.90%, 9.45-11.12%, 10.06-11.25% and 9.35-10.35% respectively. The ranges in the values of total protein, water soluble protein, dry matter, polysaccharide, total sugar, reducing and non-reducing sugar compositions of rice were 12.45--14.06%, 3.20-4.71%, 89.10-90.02%, 10.95-12.25%, 4.35-4.96%, 1.15-1.45%, and 3.10-3.58% respectively. Vitamin B1 and Vitamin B2 contents of rice were found to be ranged from 2.98-3.81 and 0.61-0.86 mg/100 gm of rice respectively. Twelve amino acids were detected in all of the four varieties of rice in the total form by paper chromatography. Rice contained about 14.95-16.16% oil. Triglyceride, diglyceride, monoglyceride, and non-glyceride were found to be varied from 91.76-93.08%, 1.51-2.30%, 1.45-1.96% and 3.63-5.24% respectively. Rice oils contained mostly unsaturated fatty acid which was varied from 71.06-74.95%. Total lipids were fractionated into lipid classes by silicic acid column chromatography.
