EVALUATION OF THE SUNSCREEN LICHEN SUBSTANCES USNIC ACID AND ATRANORIN -

[摘要] ABSTRACT: Usnic acid and atranorin are known as both sunscreen substances in natural lichen population and cytotoxic substances on human cell lines. Both substances were isolated from the acetone extracts of Cladonia foliacea and Pseudevernia furfuracea, respectively. Their photoprotective activities on irradiated human keratinocyte (HaCaT) cells and destructive effects on non-irradiated HaCaT cells were compared by a modified method in order to assess the effects on mitochondrial metabolic acti.
