Abstract

Epicuticular waxes play a role in plant biology in water loss regulation as the cuticle acts as a barrier to water vapor, influencing cuticular transpiration and as a protective barrier against environmental humidity fluctuations. Chemical composition of leaf epicuticular wax was studied in Polygonum glabrum Willd. The leaf epicuticular wax was obtained by cold extraction in n-hexane and then analyzed by Gas Chromatography / Mass spectrometry (GC/MS). The principal components of the wax were alcohols, fatty acids and n-alkanes. The most abundant compounds were 6,6-dimethyl-1,3-heptadien-5-ol (11%), oleic acid (10.59%), 9-octadecenamide, (Z)- (9.85%), 1,2,3-propanetriol diacetate (9.35%) and Octacosane (6.25%). These results provide the first report of the n-hexane–soluble epicuticular wax composition of P. glabrum, contributing to our understanding of its ecological adaptations and potential bioactive properties.
