§ 189. RARER ALKALOIDS. ^ 203 



Conessine or ivriglUine, see Haines' and Stenhouse.^ It is very 

 sparingly soluble in alcohol, ether, and bisulphide of carbon. 



Harmaline and Imrmine, compare Fritsche.^ The former yields 

 yellow salts with acids — the latter colourless. Both are some- 

 what sparingly soluble in alcohol. 



Surinamine is also sparingly soluble in spirit. (Compare Hütten- 

 schmidt and Winkler.*) 



Aribine, see Rieth.^ It is sparingly soluble in ether, as is also 



Atherospermine, compare Zeyer -j^ and Rlwadine, compare Hesse." 

 The latter is colourless, but is converted by dilute acids into 

 deep red rhoeagenine. 



Violine, compare Boullay;^ for heberine, see Maclagan ^ (cf. § 171); 

 for helladonnine, see Hiibschman ;^° for cocaine and hygrine, compare 

 Niemann, Wöhler, and Lossen.^^ Concentrated hydrochloric acid 

 decomjDoses cocaine into benzoic acid, and the alkaloidal ecgonine. 



For chlorogenine and ]Jor])hyrvne see Hesse. ^^ Chlorogenine in 

 acid solution shows a powerful blue fluorescence. 



Corydaline, compare Wackenroder, Müller and Leube, Boedecker 

 and Wicke. 1^ The alkaloid dissolves in cone, sulphuric acid, with 

 dark red colouration. 



Cytisine, compare Husemann and Marme.^*
