本文报道了对犬弓蛔虫Toxocara canis二期幼虫具杀线虫活性的植物挥发性部分(精油)的系统研究。杀线虫活性的药理指标为幼虫在被试物溶液中于37℃孵化24h后的相对移动值(RM_(24))和致幼虫死亡的被试液最低浓度(MIC)。RM_(24)、MLC值越小则活性越高。用lmg/ml、0.1mg/ml的精油及某些植物的提取部分为样品进行筛选,发现70％的精油在1mg/ml时均有强活性(RM_(24)=0),而0.1mg/ml浓度下仍有强活性的只有五个样品:即肉
In this paper, a systematic study of the nematicidal activity of nematode on the second instar larvae of Toxocara canis has been reported. The pharmacological index of nematicidal activity is the relative movement value (RM 24) of the larvae incubated in the test substance solution at 37 ° C. for 24 hours and the minimum test solution concentration (MIC) of the larvae killed. RM_ (24), the smaller the MLC value, the higher the activity. The extracts of lmg / ml, 0.1mg / ml and the extracts of some plants were screened and found that 70% of the essential oils were highly active at 1mg / ml (RM_ (24) = 0) There are only five samples that are still active at a concentration of ml: meat
