我国的萱草属植物种类很多,分布广泛,为了证实萱草属不同种植物根的毒性,本研究通过动物(山羊、家兔、小白鼠)中毒试验和萱草根素的分离鉴定,对六种萱草根进行了比较研究。试验结果:从野黄花菜根和北黄花菜根中分离得到有毒成分——萱草根素。野黄花菜根粉、北黄花菜根粉和萱草根素均能使动物发生瞳孔散大、失明、瘫痪、尿闭和死亡。而黄花菜根、萱草根、千叶萱草根和长苞萱草根则无上述毒害。这些结果表明,萱草属不同种根的毒性确有显著差异,这种差异取决于各种萱草根中是否含有萱草根素。另外,讨论了羊、牛萱草根中毒发生的地区性与萱草属某些种的分布关系以及本病的早期诊断等问题。
There are many species of Valeriana plants in China and they are widely distributed. In order to confirm the toxicity of different plant species of Valeriana, this study was conducted through the animal (goat, rabbit, mouse) poisoning test and the isolation and identification of barnyard grass roots to six kinds of barnyard grass roots. A comparative study was conducted. Test results: Weedy root element was isolated from the root of wild beetroot and the root of northern lily. Wild lily flower root powder, northern lily flower root powder and barnyard grass root root can all cause mydriasis, blindness, convulsions, urine closure and death in animals. The lily root, valerian root, Chiba grass root and valerian root were not poisoned. These results indicate that there is a significant difference in the toxicity of different roots of Valeriana, and this difference depends on the presence or absence of Valerianin in various Valerian roots. In addition, the relationship between the regional distribution of some poisonous occurrences of sheep and burdock grass roots and some species of Valeriana and the early diagnosis of this disease were discussed.
