Extraction conditions: DES composition molar ratio of 1:2, liquid–solid ratio of 40 mL/g, water percentage of 30%, temperature of 318.15 K, and extraction time of 60 min. The aucubin amount (mg/g) is expressed based on mg of aucubin equivalent per g of raw material (mg aucubin/g raw material) and the results are expressed as mean ± standard deviation (n = 3).
