Quantitative variations of phenolic compounds related to thallus age in Umbilicaria antarctica in Antarctica
Listed in NASA Earthdata CMR
Densitometric analysis (HPTLC) was used to determine the concentrations of phenolic metabolites in thalli of different ages in Umbilicaria antarctica Frey et Lamb.
Description
Usnic acid and atranorin concentrations are highest in individuals of the youngest age class and decrease towards the oldest age classes, whereas gyrophoric acids is more abundant in intermediate age clases. Usnic acid and atranorin are present in isolated rhizines.
The importance of the spatial distribution of atranorin and usnic acid in this species is discussed.
