Plants of the <i>Asteraceae</i> family have been used in traditional medicine for thousands of years. Now, forgotten for some time, they are gaining popularity again. The aim of this study was to determine and compare the proximate composition and antioxidant activity of inflorescences and leaves of <i>Taraxacum officinale</i> F.H. Wigg. (common dandelion), <i>Tanacetum vulgare</i> L. (tansy) and <i>Solidago virgaurea</i> L. (European goldenrod). The content of dry matter, crude protein, crude ash and crude fat was determined according to the Association of Official Analytical Chemists (AOAC). The content of total polyphenols was determined using methanol extracts. Antioxidant activity was determined by three methods. The protein content was the highest in <i>Taraxacum officinale</i>. The fat and ash content increased in the sequence of <i>Solidago virgaurea</i> < <i>Tanacetum vulgare</i> < <i>Taraxacum officinale</i>. The total content of polyphenols in the material and its antioxidant activity (AA) were different between species. Changes were also observed in the morphological parts of the plants. The results of the research encourage the use of not only those parts of plants known but also inflorescences or leaves, which can be excellent ingredients for drugs and other preparations used in medicine or cosmetology and also in the food industry.
