Abstract
The aim of the research is to determine the effectiveness of ultrasonic extraction of nettle seeds (Urtica dioica) whose products can be used as potential metal corrosion inhibitors. Different solvents were used (water, methanol, ethanol, acetone) in terms of total phenol content (TPC), flavonoids (TFC) and antioxidant activity (DPPH and FRAP). The results show that the aqueous extracts have the highest TPC and antioxidant capacity in both tests. The high correlation between TPC and antioxidant activity (R ≈ 0.98) confirms that phenolic compounds are key contributors to antioxidant capacity. These findings suggest that nettle seeds can be examined as a potential metal corrosion inhibitor.
