Abstract
The study of acetone-extractable components from the leaf fibers of the non-wood plant abaca (Musa textilis) resulted in the isolation and identification of series of intact hydroxycinnamate esters consisting of ferulic and p-coumaric acids esterified to long-chain fatty alcohols (C20 to C28) and ω-hydroxyfatty acids (C22 to C28). These series of compounds were characterized by high-temperature gas chromatography/mass spectrometry (GC/MS) using capillary columns (12 m length) with thin films that allowed the analysis of intact (i.e., without prior saponification) hydroxycinnamate esters. Characterization of intact individual compounds was achieved based on the mass spectra obtained by GC/MS of the underivatized compounds and their methyl and/or trimethylsilyl ether derivatives.
