摘要： Hesperidin, also known as vitamin P, is widely studied for its distinctive potential in food and pharmaceutical industries. This work focuses on the research of CO2-responsive deep eutectic solvents (DESs) used as recyclable extractants for efficient extraction of hesperidin from Fertile orange peel. Reversible phase transformation of DES solution was achieved by bubbling CO2/N2. The maximum extraction yield of 22.39 mg/g was obtained for hesperidin under the following conditions: DES-6 (triethanolamine: 4-methoxyphenol = 1:1) used as extractant, water content of 35 wt%, solid-liquid ratio of 1:60 g/mL, extraction temperature of 25 degrees C, and ultrasonic time of 25 min, which was much higher than that extracted by methanol. Hesperidin of 74.38% was recovered in top phase after CO2 triggering. Density function theory (DFT) results indicated that hydrogen and & pi;-& pi; bonds were the main factors affecting hesperidin extraction. This study provides a new idea for extracting natural bioactive compounds using recyclable extractants.
