有毒植物广泛分布的印花布世界。这些植物毒性的诊断非常困难。我们选择五有毒植物Al - Hassa在沙特阿拉伯东部地区,Anagallus薄荷,旋花植物薄荷,大戟属植物helioscopia, Sisymbrium irio Withania somnifera。LD50这些植物是10.718,500.0,1211.7,4.133,522.27毫克/公斤。分别bwt ip的老鼠。老鼠中毒a .薄荷遭受fromanorexia、不安、腹泻、口渴(动物用于饮用水),呼吸困难,震动和一些个人的昏迷和死亡结束。老鼠中毒c .薄荷显示轻微的毒性,它会导致腹泻、利尿、通便。老鼠中毒大肠helioscopia包括增加活动和易怒,唾液分泌,发痒的鼻子和嘴笼地板,和腹泻。动物们试图使隧道在床底下,他们不愿站在笼子的角落。动物们关闭了它的眼睛,变得平静。动物中毒s irio显示关闭眼睛,扩展头部和颈部,往往睡在胸骨,经常震动,会跳,痉挛和尾巴升高,增加呼吸,呼吸困难、黄萎病的嘴和腿,很明显黄萎病与运行时间喘气和昏迷之后,死亡的外观光泽的眼睛角膜。 Poisoning of W. somnifera increased heart and respiratory rates, unconsciousness, closed eyes, stupor and paralysis of the hind legs, after which the animals became drowsy and finally died. On the other hand, various signs appeared such as shaking of the head, licking of the legs, petecheal hemorrhages from the eye canthus, lying on the sternum, creeping on the abdomen. Diarrhea occurring on the 2nd day and lastly irregular gasping fits ending by coma and death. In the present study, the aqueous extracts of the Withania somnifera, Convolvulus arvensis and Sisymbrium irio inhibited superoxide radical generation. The aqueous plant extracts exhibited different degradation effect on both DNA and bovine serum albumin. There are diverse antibacterial effects of the aqueous extracts on both GramsÂ’ positive and negative bacterial strains.
