白曼陀罗叶(チョゥセソアサガォ) 原植物Datura metel L.花期的叶。科名Solanaceae(茄科) 理化反应1.粉末1克加乙醚10毫升及NH_4OH试液0.5毫升,温浸30分钟后过滤,滤液盛入磁皿或蒸发皿内,在水浴锅上蒸发乙醚之后,其残渣加发烟硝酸5滴,再在水浴锅上蒸干之后冷却,残渣加二甲基甲酰胺1毫升溶解,再加氢氧化四乙铵溶液(2克+水→5毫升)5滴时,溶液成红紫色(天仙子胺,阿托品,东莨菪碱。另外,可用薄层层析法鉴别阿托品和东莨菪碱)。2.粉末3克,加CHCl_3 10毫升,仔细振摇混合过滤,滤液5毫升加NH_4OH试液5毫升,振摇混
White Mandala Leaves (Pteris) Original plant Datura metel L. Leaves of the flowering period. The scientific name Solanaceae (Solid Solanaceae) Physicochemical reaction 1. Powder 1 gram plus diethyl ether 10 ml and NH 4 OH test solution 0.5 ml, warm immersed for 30 minutes, filtered, the filtrate was placed in a magnetic dish or evaporating dish, after evaporating the ether in a water bath, The residue is added with 5 drops of fuming nitric acid, and then evaporated in a water bath and then cooled. The residue is dissolved in 1 ml of dimethylformamide and 5 drops of tetraethylammonium hydroxide solution (2 g + water → 5 ml) is added. The solution turns red-violet (cystine amine, atropine, scopolamine. In addition, atropine and scopolamine can be identified by thin layer chromatography). 2. 3 g of powder, add 10 ml of CHCl 3 , carefully shake and filter. Add 5 ml of NH 4OH solution to the filtrate and shake
