Alkaloids of Cyphomandra betacea sendt

A new base, solacaproine [NN-bis-(4-dimethylaminobutyl)hexanamide], has been isolated from the roots of Cyphomandra betacea; it is the N-hexanoyl derivative of solamine. Other bases identified include solamine (principal component), tropinone, and cuscohygrine. The presence of hyoscyamine (atropine), tropine, Φ-tropine, tigloidine (1αH,5αH-tropan-3β-yl 2-methylcrotonate), and a homologue of solacaproine is tentatively reported.
