翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク On a New Organic Base in the Coca Leaves ： ウィキペディア英語版 On a New Organic Base in the Coca Leaves ''On a New Organic Base in the Coca Leaves'' is an 1860 dissertation written by Dr. Albert Niemann. Its title in German is ''Über eine neue organische Base in den Cocablättern''. The piece describes, in detail, how Niemann isolated cocaine, a crystalline alkaloid. It also earned Niemann his Ph.D. and is now in the British Library. He wrote of the alkaloid's "colourless transparent prisms" and said that, "Its solutions have an alkaline reaction, a bitter taste, promote the flow of saliva and leave a peculiar numbness, followed by a sense of cold when applied to the tongue." Niemann named the alkaloid "cocaine" — as with other alkaloids its name carried the "-ine" suffix. ==External links== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「On a New Organic Base in the Coca Leaves」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
