Valorization of Yarrow (Achillea millefolium L.) By-Product through Application of Subcritical Water Extraction
In the present study, valorization of yarrow (Achillea millefolium) by-product from the filter tea industry was investigated through the application of subcritical water for the extraction of bioactive compounds. The influence of di erent process parameters (temperature 120– 200 C, extraction time 10–30 min, and HCl concentration in extraction solvent 0–1.5%) on extract quality in terms of content of bioactive compounds and antioxidant activity was investigated. Optimal conditions of the extraction process (temperature 198 C, extraction time 16.5 min, and without acidifer) were determined and, when applied, the most ecient exploitation of by- products is achieved, that is, attainment of extracts rich in total phenols and flavonoids and high antioxidant activity. In addition, by applying the high performance liquid chromatographic analysis, the content of chlorogenic acid was determined as well as the hydroxymethylfurfural content in obtained extracts. The results demonstrated that subcritical water can be successfully used for utilization of yarrow by- products for obtaining extracts rich in antioxidants.
