AbstractCalluna vulgaris (L.) Hull (heather) is the only species within the genus Calluna (Ericaceae). It is a dominant species of heather communities and can be found in most parts of Europe and Northern America from lowland up to alpine regions. Common heather is traditionally used to treat urinary tract disturbances and inflammatory related disorders. This review covers the current knowledge on phytochemical investigations of C. vulgaris which revealed a complex pattern of flavonoid glycosides including acetylated compounds as well as other classes of phenolics (chromones, procyanidins and simple phenols). Recently, an acetophenone (rodiolinozide) was identified. C. vulgaris occurs in habitats comprising several altitudinal zones which makes it an attractive species to study the variation of its metabolic profiles in wild populations growing under different climatic Calluna vulgaris (L.) Hull (heather) is the only species within the genus Calluna (Ericaceae).

Common heather is traditionally used to treat urinary tract disturbances and inflammatory related disorders. This review covers the current knowledge on phytochemical investigations of C. vulgaris which revealed a complex pattern of flavonoid glycosides including acetylated compounds as well as other classes of phenolics (chromones, procyanidins and simple phenols). Recently, an acetophenone (rodiolinozide) was identified. C. vulgaris occurs in habitats comprising several altitudinal zones which makes it an attractive species to study the variation of its metabolic profiles in wild populations growing under different climatic conditions. Within phenolic compounds, flavonols showed significant differences in samples collected at different altitudes with increased levels of quercetin glycosides at higher altitudes whereas no significant correlation could be found for caffeoyl quinic acids and the dihydroflavonol glycoside callunin. Expanding such investigations to different species and different geographical areas should give a more accurate picture of suitable marker compounds within the group of phenolics in order to detect adaptive processes in high altitude plants. Furthermore, investigations on the specific patterns of phenolics at cellular and subcellular level and their variation due to factors like enhanced solar radiation and low temperature should be expanded
