摘要 梅州山区常有误食大茶药类植物煲汤引起食物中毒的事件发生,因此必须建立一种快速、简便的钩吻生物碱检测方法,以便为抢救中毒者提供实验室依据。取引起食物中毒的汤料植物,用0.3molL醋酸溶液浸泡后,浸泡液调至碱性,用乙醚提取,挥干乙醚后,残渣用“重铬酸钾-硫酸反应”和“钒硫酸反应”进行定性检测,同时用已知可食用的植物(马蓝等)做阴性对照。在几起此类食物中毒事件中,汤料植物均检出钩吻生物碱。本法操作简便,试剂易得,结果易于辨别,不需使用贵重仪器,适合在基层疾病预防控制中心检验室推广使用。 Some people drank boiled soup of plants like gelsemine mistake, which made them poisoned. These cases happened from time to time in Meizhou. Therefore, should be found a method to test Gelsemium elegans Benth easily, quickly, so that provide laboratory basis to save the lives of the poisoners. The soup plants should be taken from the poisonous soup and then immersed in the liquid of acetic acid(0.3 mol/l),which should be adjusted to alkalinity. After the plants are extracted by means of aether and aether is volatilized, the dregs should have a qualitative test using “Potassium dichromate-Sulphuric acid reaction' and “Vanadium Sulphuric acid reaction'. Meanwhile, they should have a negative comparison with the known, eatable plants(Baphicacanthus cusia(Nees) Brem. et al). In several cases of food poisoning, Gelsemium elegans Benth is obtained from the soup plants after a test. This method can be used widely in the labs of Center for Disease Prevention and control in grass-roots Units, because it can be operated easily and reagent can be obtained easily. Besides it's easy to distinguish the results without using any expensive equipment.
