Natural occurrence of guanidinooxypropylamine in Wistaria floribunda and the sword bean Canavalia gladiata.
We found a new guanidinooxyamine in Wistaria floribunda seeds and seedlings of the sword bean, Canavalia gladiata. This amine was not only ninhydrin-positive but also gave a positive alkaline nitroprusside-ferricyanide reaction. It was characterized as gamma-guanidinooxypropylamine [H2N (NH=)CNHO (CH2)3NH2] by comparison with the authentic compound on column and thin-layer chromatograms visualized with specific reagents and by reductive cleavage. Evidence for the occurrence of another unusual guanidino amine, homoagmatine in W. floribunda seeds was also presented.
