摘要:研究氯化胆碱低共熔溶剂(DES)提取野菊花中的总黄酮、总槲皮素和槲皮苷。首先,合成了 4 种性能
优异的 DES,并对其物理性质进行表征。其次,以提取效果最好的氯化胆碱/尿素 DES 为溶剂,通过改变单一
变量优化提取效果,在含水量 30%、提取时间 45 min、固液比 1∶50 (g∶mL,下同)、提取温度 60 ℃的条件
下,总黄酮、总槲皮素、槲皮苷的提取得率分别为 72.32、12.97、10.06 mg/g,提取效果优于传统有机溶剂。SEM
和 XRD 结果表明,在提取过程中野菊花的晶体结构无明显变化,DES 使野菊花表面形貌发生较大改变,使其
具有更强的细胞破壁效果,导致黄酮类化合物更易溶出。

Abstract: Green deep eutectic solvents (DES) synthesized by choline chloride (ChCl) were applied to
extract the total flavonoids, total quercetin and quercitrin from Chrysanthemum indicum L. Firstly, four
kinds of DES with excellent performance were synthesized and their physical properties were characterized.
Secondly, urea-choline chloride with the best extraction effect was used as solvent to optimize several
parameters affecting the extraction effect. Under the extraction conditions of water content of 30%,
extraction time of 45 min, solid-liquid ratio of 1∶50 (g∶mL, the same below), extraction temperature of
60 ℃, the extraction yields of total flavonoids, total quercetin and quercitrin were 72.32, 12.97 and 10.06
mg/g, respectively, better than that extracted by traditional organic solvents. SEM and XRD results showed
that Chrysanthemum indicum L. had no obvious change in crystal structure during the extraction process,
but the surface morphology change significantly. DES enabled Chrysanthemum indicum L. to have a
stronger cell-breaking effect, resulting in easier dissolution of flavonoids.
