The methanol crude extracts of the plant parts of Mimosa pudica (Mimosaceae) was screened was screened in vitro for antioxidant activity using the 1, 1-diphenyl-2-picrylhydrazyl-hydrate (DPPH) free radical scavenging assay. On the other hand, the methanol crude extract of the aerial part showed moderate antioxidant activity (IC50 20.512 μg/ml) compared to ascorbic acid (IC50 1.143 μg/ml). The overall experimental results suggest the biologically active constituents present in the methanolic extract of Mimosa pudica and justify its use in folkloric remedies.Keywords

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 nonglyceride 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.Keywords
