| Abstract | ||
| Three preparations of dried oleander leaves were prepared. The first one was by extraction with hexane; the second by extraction with 70% ethanol while the third was suspended as a whole ground leaves in distilled water. Different concentration of each form was prepared and the range of lethal dose in mice had estimated by pilot studies. The acute toxicity study was carried out by determine the median lethal dose (LD50) after administration of each preparation using 5 subgroups (10 mice) each receive dose range from 60-64 mg/kg, 504-536 mg/kg and 1100-1300 mg/kg for the hexane extract , ethanol extract and leave suspension respectively. The lethal dose calculated by employing probit method and found to be; 62.6 mg/kg for hexane extract, 521.0 mg/kg for ethanol extract and 1164.8 for leave suspension. This result indicates that the toxic constituents of the leaves are mostly non-polar, also that the potency of toxicity is far less than that mention in some literature. | ||
