PHENOLIC ACIDS AND LIGNINS IN THE LYCOPODIALES,
Abstract
Twenty-one species and varieties of Lycopodium have been examined for phenolic acids and for phenolic aldehydes, ketones and acids obtained on ethanolysis or alkaline oxidation of their extracted wood-meals. p-Hydroxybenzoic, vanillic, p-coumaric and ferulic acids were identified in phenolic acid fractions and p-hydroxybenzaldehyde, vanillin, acetovanillone, vanilloyl methyl ketone, alpha-hydroxy- and alpha-ethoxypropiovanillone were identified among the products of lignin degradation. Those species which are included in the genera Lycopodium and Diphasium, as proposed by Rothmaler, were found to yield syringic acid in the ethanol-soluble fraction and on degradation of lignin whereas species included in the genera Huperzia and Lepidotis did not. Syringaldehyde was not obtained on alkaline oxidation of the lignin of any species thus indicating that Lycopodium s. lat. has essentially a gymnospermous type of lignin. Sucrose was identified as the major carbohydrate in ethanolic extracts. (Author)
