| Abstract Detail
Phytochemical Section Pirone, Cary [1], Lee, David [2], Quirke, Martin [3], Kress, John [4]. Two Unique Aril Pigments in the Strelitziaceae (order: Zingiberales). Plant pigments perform important ecological and physiological functions, yet little information is available regarding many of these compounds. Our work focuses on several unidentified pigments found in the arils of three species in the Strelitziacae, Ravenala madagascariensis, Phenakospermum guyanense, and Strelitzia nicolai. Previously, we discovered a novel blue protein pigment complex in R. madagascariensis. Here, our focus is the identification of two unusual pigments, one orange and one yellow, found in P. guyanense and S. nicolai. Chemical structures are identified using mass spectrometry (MS) and nuclear magnetic resonance spectroscopy (NMR). Structures, along with chemical properties and cellular distribution will be discussed in an evolutionary context within the order Zingiberales.
