# Chemical Composition and Antioxidant Activity of _Asteraceae_ Family Plants
## 3 Results
### Comparison: Species \(\times\) Part of Plants Interaction  
#### 3.2.1 Proximate Composition  
Among the analyzed morphological parts of the three studied species, the leaves of common dandelion had the highest dry matter content (93.09%), and the leaves of tansy were the lowest (91.27%) (Table 3). The high content of dry matter in the leaves of common dandelion was accompanied by the accumulation of the largest amount of crude protein (16.91% DM) and crude ash (11.78% DM) compared to other raw materials. Tansy leaves were characterized by the highest carbohydrate content (49.84% DM). The highest content of crude fat was found in the infloresesences of common dandelion (9.15% DM), and the highest content of crude fiber was in the infloresesences of tansy (20.90% DM).
