翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tonka bean oil ： ウィキペディア英語版 Tonka bean oil Tonka bean oil is extracted from the seed of the ''Dipteryx odorata''. The oil is composed primarily of coumarin, which is used to flavor tobacco. It is neither a pressed oil, nor an essential oil, but was traditionally obtained by soaking the large, single tonka bean seed in rum or other alcohol for 24 hours, after which crystals of coumarin appear on the outside of the seed, and are collected. The seeds contain up to 46% oil by dry weight. In more recent years, most commercially produced coumarin is synthetic, which has reduced the demand for tonka beans as a crop. Coumarin derivatives are also used medicinally, as anti-coagulants.〔(【引用サイトリンク】title=Dipteryx odorata )〕 == References == 〔 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「Tonka bean oil」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.
