説明
This alkaloid occurs with Evodiamine (q.v.) in the Chinese drug 'Wou-chou-yu'
which is the dried fruit of Evodia rutaecarpa Benth. It crystallizes from boiling
EtOH as colourless, or pale yellow, needles and is optically inactive. The acetyl
derivative has m.p. 184-6°C and the benzoyl compound, m.p. 194°C. The
alkaloid gives a yellow colour with concentrated H2S04 and is decomposed by
KOH in boiling amyl alcohol yielding anthranilic acid and 3-{3-aminoethylindole-
2-O!carboxylic acid, CllH120 2N2, silky crystals, m.p. 257°C.
Pharmacologically, the alkaloid causes increased arterial pressure on injection.
