Green Methods for Extraction of Inulin and Antioxidants from Carlina acanthifolia L. Roots – A Comparative Study

Green extraction methods present a perspective approach for the isolation of bioactive molecules. Together with an ecofriendly to extraction, there are many undervalued plants - rich source prebiotics and phenolic compounds. Carlina acanthifolia L. roots possessed antimicrobial, anti-inflammatory, anti-ulcer properties due diverse compounds in them. Detailed information about inulin-type fructan its is still absent. The object this work was define inulin, sugars, content, antioxidant activity water, 70 % ethanol extract resulting from ultrasound-assisted (UAE) pressure-liquid (PLE). results showed that total fructans reached 12.6±0.2 g/100 g dw. Inulin found water extracts (6.82 dw) prevalence extracts. Total content did not exceed 15.25 mg GAE/g Additionally, activities were range 5.99 205.83 μM TE/g In conclusion, UAE demonstrated higher levels antioxidantive properties, probably cavitation process. However, study first detailed investigation polyphenols as well obtained by green methods. Therefore, research enriched roots.
