The alkaloid, dehydroevodiamine, m. p. 189-190°, obtained from the leaves of Evodia rutaecarpa HOOKER FIL. ET THOMSON, was assined the structure of an anhydronium base by the following reasons.
1) Crystals have a beautiful red color which is common to anhydronium bases.
2) Basicity is stronger than evodiamine and bathochromic shift in spectrum is observed in dilute alkali solution.
3) There is no absorption of indole NH in its infrared spectrum.
4) Application of methyl iodide results in formation of an indole N-methyl derivative and this was derived to 13-methylrutaecarpine and 13-methylevodiamine.
