Cytotoxic activities of Rosa brunonii,Calligonum polygonoides,Pegnum harmala and Sueda fruticosa extract using brine shrimp

The present study was carried out to record and evaluate the effect of rosa brunonii,calligonum polygonoides,sueda fruticosa and pegnum harmala l.,extracts on brine shrimp collected during march-june 2013 from different regions of district bannu. these four plants were medicinal xerophytes and widely distributed throughout pakistan. rosa brunonii is commonly used as a hedge plant for gardening. calligonum polygonoides and sueda fruticosa are locally used as a fuel,while pegnum harmala (l.) is the most important multipurpose medicinal xeric plant,which is used for various purposes. all these selected medicinal xerophytes have inhibitory effect on bacterial growth. in this study the effect of different concentration (10-70 μg/ml) were tested on brine shrimp. the results showed that maximum cytotoxic activities were observed in rosa brunonii (100.0±0.4),calligonum polygonoides (100.0±0.2) and pegnum harmala (l.) (90.0±5.2) while sueda fruticosa (50.0±7.1) has less cytotoxic property. these activities are may be due to the presence of bioactive constituents.
