The same population of the polytrichaceous moss Polytrichum formosum was
studied over four different periods of the year, analysing its carbohydrate and
polyphenolic content and dynamics related to environmental seasonal changes. A
total of 18 different types of sugars (including mono-, di-, tri- and tetra-saccha rides) and four sugar alcohols were determined. Chlorogenic acid was the most
represented among the 10 detected phenolic compounds. As inferred by the sugar
content, sucrose, fructose and glucose were the most dominant sugars, but it is
worth mentioning the abundance of trehalose and turanose at least during one of
the observed seasons. The presence of four trisaccharides and one tetrasaccharide
within P. formosum should be highlighted, as well as the first reports of turanose,
isomaltotriose, panose and rhamnose within this species. The quantitative changes
over the year clearly demonstrate carbohydrate dynamics in relation to seasonal
climatic variation. Sugars are shown to be significant constitutive molecules within
P. formosum, but also physiologically active compounds, i.e. signalling and energy
storage and supplier molecules. We assume that phenolics have moss-supportive
effects during oxidative stress and biotic interaction.
