The single factor experiments were performed in several combinations, with seven parameters, including different IL concentrations (0.2–1.6 M), concentration of ethanol (40%–100%), liquid–solid ratios (5–120 g/mL), particle size (20–70 mesh), ultrasonic time (10–90 min), centrifugation speed (3000–9000 r/min), and ultrasonic power (120–500 W) in the ultrasonic extractor. The significant factors were chosen by the PB design using Design-Expert 8.0.6 Trail software (Stat-Ease, Minneapolis, MN, USA). Then, a Box–Behnken design (BBD) was applied for the RSM optimization using Design-Expert 8.0.6 Trail software.

Firstly, the extraction yields of DMY were studied through a series of single factor tests with the important extraction parameters, including water concentration (10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% v/v), shaken time (0.5, 1, 1.5, 2, 2.5, 3 and 3.5 h), liquid–solid ratios (5, 10, 20, 30, 40 and 50 mL g−1) and temperature (30, 35, 40, 45, 50, 55 and 60 °C). According to the above single factor experimental results, a Box–Behnken design (BBD) based on RSM was applied for the optimization of the extraction conditions with the Design-Expert 8.0.6 Trail software (Stat-Ease, Minneapolis, MN, USA). The chosen key factor boundaries of the water contents (A), extraction temperature (B), and extraction time (C) are listed in Table 2 , while the liquid–solid ratio was fixed at 20 mL g−1. The experiments were performed in random order to avoid systematic errors.

The single factor experiments were performed in several combinations, such as using different ionic liquid concentration (0, 0.25, 0.5, 0.75, 1, 1.25, and 1.5 mol/L), liquid-solid ratios (10, 20, 30, 40, 50, 60 g/mL), extraction times (10, 20, 30, 40, 50, 60, and 90 min), and ultrasonic power (120, 180, 240, 300 W) in the ultrasonic extractor. A Box–Behnken design was applied for RSM optimization with Design-Expert 8.0.6 Trail software (Stat-Ease, Minneapolis, MN, USA). Based on the above single factor experimental results, the chosen factor boundaries of ionic liquid concentration (A), liquid-solid ratio (B), and ultrasonic time (C) were listed in Table 2 . The experiments were performed in random order to avoid systematic errors.

The preparation process of TG-KF and the principle of PEF are shown in Fig. 3 and 4 . The single factor experiments were performed in several combinations, such as using different DES concentration (10%, 20%, 30%, 40%, and 50%), solid–liquid ratios (1 : 10, 1 : 20, 1 : 30, 1 : 40, and 1 : 50), electric field strength (0.14, 0.27, 0.41, 0.55 and 0.68 kV cm−1) and pulse numbers (20, 30, 40, 50, and 60 times) in the high-voltage pulsed electric field extractor. A Box–Behnken design was applied for orthogonal experiment with Design-Expert 8.0.6 Trail software. Based on the above single factor experimental results, the chosen factor boundaries of DES concentration (A), liquid–solid ratio (B), electric field strength (C) and pulse numbers (D) were listed in Table 2 . The experiments were performed in random order to avoid systematic error.24 (link)
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
