|Section2= |Section3= }} Cinobufagin is a cardiotoxic bufanolide steroid secreted by the Asiatic toad ''Bufo gargarizans''. It has similar effects to digitalis and is used in traditional Chinese medicine. ==Isolation & Purification== Cinobufagin, as well as other bufadienolides, can be isolated from the traditional Chinese medicine called ChanSu. ChanSu is made from a multitude of chemicals present in Bufo gargarizans secretions. Resibufogenin can be eluted out with silica gel column chromatography, using a 5:1 ratio of cyclohexane to acetone for the solvent in the mobile phase. Subsequently, cinobufagin and bufalin can be separated and purified using an HPLC column with a 72:28 methanol to water solvent. Yang et al. confirmed this method of isolation for cinobufagin with Proton NMR. 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「Cinobufagin」の詳細全文を読む スポンサード リンク
