Mit der Eberesche vom Heimatlied zur Frühstücksmagarine

The mountain ash (rowan tree) belongs to the adaptable trees of pioneer vegetation. Its fruits are edible and can be used for dishes and beverages. Appropriate knowledge is, however, required to avoid dissapointments. Their use in folk medicine is also known. In the German Ore Mountain region there is a special folk song as a song of praise for the tree. Typical chemical ingredients are the constituents parasorboside ( 1 ), a glucoside, parasorbinic acid ( 2 ), a lactone, and sorbinic acid ( 3 ), an unsaturated carboxylic acid. It is chemically accessible from 2 and used as a preservative. In more than 100 years, the structures were determined by renowned chemists. The access to 1 , 2 , and 3 based on the mountain‐ash rowan berries is described. All analytical spectra were recorded and are reproduced and interpreted either in the main part or in the supporting information.
