Structural Elements of Sporopollenin from the Pollen of Torreya californica Torr. (Gymnospermae): Using the ¹H-NMR Technique

Abstract

Abstract Sporopollenin was isolated and purified from pollen of the gymnospermae Torreya californica using an enzymatic treatment followed by extraction with organic solvents. 1 H -NMR (ID and 2D) was used for analysis of this biopolym er and reveals the presence of three phenolic com pounds. Comparison with the analysis of sporopollenin from the angiospermae Typha angustifolia L. shows high similarity between the aromatic compounds
