title: An amide of L-threo-gamma-hydroxyglutamic acid from Justicia ghiesbreghtiana.
abstract: A new amide of threo-gamma-hydroxyglutamic acid, justiciamide, was isolated from Justicia ghiesbreghtiana and shown to be (-)-N-(2-hydroxy-4,5-dimethoxyphenyl)-(2 S,4 S)-gamma-hydroxyglutamic acid. Justiciamide is the first amide of an uncommon amino acid found in this genus.
