Abstract A new Schiff's base, named isocraugsodine, was isolated from the fruits of Crinumasiaticum . Its N -(3- methoxy-4-hydroxybenzylidene)- 4′-hydroxyphenethylamine structure was assigned on the basis of chemical trans- formation and comprehensive spectroscopic evidence. The temperature-gradient distribution of the three isomeric forms ( 1a ⇌ 1b ⇌ 1c ) of the Schiff's base was determined by high
