Abstract

Rutin from Ginkgo biloba L. leaves (78.63 mg g⁻¹) was mildly and effectively extracted using an ultrasound-assisted process with tailor-designed natural deep eutectic solvent-based cellulose polymer adsorbents. The physicochemical properties and structural characteristics of the synthesized natural deep eutectic solvent-modified cellulose polymers were examined by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, thermogravimetric analysis, and elemental analysis. The ultrasound-assisted extraction conditions were optimized using a response surface methodology (extraction time, 40 min; sample to solvent ratio, 1:29 g/mL; extraction temperature, 81 °C; and ultrasound frequency, 180 W). The ultrasound-assisted extraction method is environmentally friendly and allows the simple and easy recovery of components. In addition, this approach is effective for the extraction, separation, and detection of rutin. These findings might promote the applications of rutin from G. biloba L. leaves in several fields.

摘要

来自银杏的芦丁。叶 (78.63 毫克 g ^-1) 使用超声波辅助工艺和量身定制的天然低共熔溶剂型纤维素聚合物吸附剂温和有效地提取。采用傅里叶变换红外光谱、场发射扫描电子显微镜、热重分析和元素分析对合成的天然深共晶溶剂改性纤维素聚合物的理化性质和结构特征进行了研究。使用响应面法优化超声辅助提取条件（提取时间为 40 分钟；样品与溶剂的比例为 1:29 g/mL；提取温度为 81 °C；超声频率为 180 W）。超声辅助提取方法对环境友好，并且可以简单轻松地回收成分。此外，这种方法对芦丁的提取、分离和检测是有效的。这些发现可能会促进芦丁的应用G. biloba L.叶在几个领域。
