The influence of ultrasound assisted extraction on the isolation of bioactive compounds from nettle leaves

Urtica dioica L., commonly known as nettle, is a perennial plant from the Urticaceae family. Nettle leaves are rich in bioactive compounds, such as the phenolic compounds, which are exceptionally important for the growth and reproduction of the plant and are considered to have a significant effect on human health and are strong antioxidants. For the isolation of the phenolic compounds, various extraction techniques are used, such as conventional methods requiring extended extractability times and a higher amount of solvent. One of the most commonly used non thermal eco-friendly techniques for isolation of bioactive compounds from plants is ultrasound assisted extraction (UAE), whose advantages are shortening the time of extraction, reduced solvent consumption, reduced extraction temperature, and lower energy consumption. Hence, the aim of this study was to determine the optimal conditions for the extraction of phenolic compounds in dried nettle leaves (Urtica dioica L.) using ultrasound assisted extraction (UAE) with GRAS solvent 96% ethanol. Parameters varied during the experiment were: the amplitude of ultrasound (25-100 %) and the extraction time (5-40 min), conducted at ambient temperature. The total polyphenolic content (TPC) of nettle extracts was determined spectrophotometrically using the Folin-Ciocalteu method. The highest yield of the total phenolics extraction was 563, 12 mg GAE/100g, achieved with the following extraction conditions: 20 minutes at an amplitude of 75 %.
