        This study was conducted to investigate the biomedicinal worth of different parts of Geranium sibiricum Antioxidant, anti-inflammatoty and anticancer activities of methanolic extracts of root and shoot of Geranium sibiricum were determined. Methanolic extracts of root and shoot parts of Geranium sibiricum had antioxidant activity in the range of 40-50 jlg mL·1, and shoot extract was best in this regard. Likewise, anti-inflammatory activities of extracts was in the range of 60-100 jlg mL-1 and root extract of Geranium sibiricum seemed more useful with 87.38% higher anti-inflammatory activity than shoot with 63.63% activity. Regarding cytotoxicty test against two cancer cell line i.e. SK-Hep1 (liver) and HeLa (uterus), the methanolic extracts of shoot and root of Geranium sibiricum showed the highest toxicity with IC50 values of 10-30 jlg mL-1 and root extract proved more beneficial in this regard. In conclusion, methanolic extract of shoot of Geranium sibiricum had higher antioxidant while root extract had higher anti-inflammatoty and anticancer activities.

        Significant variations occur in pigmented rice germplasm with respect to their antioxidant potential. Therefore this study was designed to evaluate the antioxidant potential of exotic rice germplasm collected from different parts of the globe. Grain samples of exotic rice germ plasm (21 0 accessions) were collected from different countries of Asia, America and Europe and their ground grain samples were extracted with 80% methanol at 30 oc using sonicater for 30 minutes to estimate their total polyphenol and flavonoids contents and antioxidant activity. Rice germplasm had tremendous variations with respect to total polyphenols (0.0800.71 mg g- 1) and falvonoid contents (0.091 00.413 mg g" 1 ) and antioxidant activity (18096%). Rice cultivars with red and black seed coat had higher antioxidant activity owing to significantly higher polyphenols and falvonoid contents in their grains. Therefore rice cultivars with red and black seed coat color should be included in breeding rice genotypes with higher nutritional value.
