Fig. 1From: A preliminary evaluation of cytotoxicity, antihyperglycemic and antinociceptive activity of Polygonum hydropiper L. ethanolic leaf extractDetermination of lethal concentration 50 (LC50) of P. hydropipper L. A straight line obtained by plotting percentage of mortality of brine shrimps nauplii against the logarithm of the concentration of leaf extract (from Table 1). From the graph, log LC50 was obtained at 50 % mortality. LC50 value obtained for P. hydropipper L. extract was 16.22 μg/mlBack to article page
