| Description | An oily base obtained from the bark of Cephaelis Ipecacuanha (Brot) A. Rich,
the alkaloid is characterized as the perchlorate which forms crystals of the monohydrate from aqueous EtOH, m.p. 140-2°C or 193-5°C (dry). This salt has
[α]D - 10.9° (c 3.13, EtOH) and gives an ultraviolet spectrum in ethanol with
two absorption maxima at 232 and 283 mJ1. The base contains a formylmethyl
group and yields a crystalline semicarbazone, m.p. 168-9°C. The optically
inactive base has been synthesized and is also a colourless oil, giving a semicarbazone, m.p. 185-6°C. | | Definition | ChEBI: Protoemetine is a member of isoquinolines. | | References | Battersby, Davidson, Harper.,J. Chem. Soc., 1744 (1959)
