title: NMR-based metabolic profiling of Anigozanthos floral nectar.
abstract: Nuclear magnetic resonance spectroscopic methods have been used to characterize the chemical composition of floral nectar of Anigozanthos species with a minimum of sample preparation and without derivatization. The nectar of this passerine-pollinated plant is largely dominated by glucose and fructose, while sucrose occurs only at a minor level. Tyrosine, several additional amino acids, and a variety of carboxylic acids were identified and their concentrations estimated. A linear diarylheptanoid was detected as a trace component, marking the first time this type of secondary product in Hemodoraceae has been found.
