Description

The empirical formula for this alkaloid from Croton linearis Jacq. was originally given as C 1 7H 1903N, representing it as a dihydrocrotonosine. This was later altered to that given above when it was shown that a methylimino group is present. The structure has now been confirmed as dihydro-N-methylcrotonosine. When crystallized from EtOH it forms anisotropic columns. The ultraviolet spectrum shows three absorption maxima at 228, 282 and 288 ffi/J. and the specific rotation in [o:Jf>8 + 116° (c 0.83, MeOH). The hydrochloride also forms colourless columnar crystals which decompose, without melting, above 300°C. One phenolic hydroxyl group is present and on methylation, the alkaloid yields Amuronine (q.v.).
