Xanthoria parietina Archives

Normalized bands areas of parietin (FT-IR reflectance) during UV irradiation under N2 flux showed as color gradient, where dark yellow is band's area before irradiation (100 %), orange is 50 % of beginning band's area, red is 0 % of beginning band's area and yellow is 150 % of beginning band's area. Numeric values are referred to Tab. S1. -- Science Direct

UV Photo-degradation of the Secondary Lichen Substance Parietin: A Multi-spectroscopic Analysis in Astrobiology Perspective

by Keith CowingMay 27, 2024May 27, 2024

The cortical anthraquinone yellow-orange pigment parietin is a secondary lichen substance providing UV-shielding properties that is produced by several lichen species. In our work, the secondary metabolite has been extracted […]
