Swainsonine Detoxification of Muscle Tissue Derived from Locoweeds Poisoning Naturally in Goat

疯草是我国西部草原的主要毒害草,其毒性成分为苦马豆素。本实验以内蒙古阿拉善的一只变异黄芪自然中毒山羊为对象,采集其肌肉组织,运用不同处理方法对其进行处理后,气相色谱仪检测组织中苦马豆素的含量。结果显示,室温水浸泡、室温水浸泡+超声、水蒸煮和水蒸煮+超声,4种不同处理方法对疯草自然中毒羊肌肉组织中苦马豆素的清除明显不同,分别为81.7%、94.7%、100%和100%。结果表明,采用水蒸煮的方法即可完全清除中毒羊肌肉组织中的苦马豆素。
