Abstract

For plant metabolite extraction, natural deep eutectic solvents (NADESs) have many benefits over conventional solvents and ionic liquids. These advantages include high solubility and extraction ability, a low melting point (<100 °C), low toxicity, environmental friendliness, recyclability, and better biodegradability. This study analyses a natural deep eutectic solvent for Acmella oleracea (A. oleracea) metabolite extraction, considering the following process parameters: temperature, component ratio in the eutectic solvent, water addition, solid/liquid ratio, and extraction duration. NADESs were synthesised using a simple heating method, and the synthesis of the NADESs was verified by Fourier transform infrared spectroscopy (FTIR). In terms of total polyphenol content (TPC) and flavonoid content (TFC), the betaine/propanediol ratio in a NADES of 1:3 and S/L = 1:5 yielded the highest efficiency. A value of 8.37 mg GAE/mL was obtained for TPC by ultrasound-assisted extraction with 40% water addition, 25 °C extraction temperature, and 60 min contact time. The best result in terms of TFC was 14.50 mg QE/mL obtained through ultrasound-assisted extraction with 0% water added, 25 °C extraction temperature, and 60 min contact time.

利用天然深层共晶溶剂萃取油菜籽代谢物

与传统溶剂和离子液体相比，天然深共晶溶剂（NADES）在植物代谢物萃取方面有许多优点。这些优点包括高溶解度和萃取能力、低熔点（<100 °C）、低毒性、环保、可回收性和更好的生物降解性。本研究考虑了以下工艺参数：温度、共晶溶剂中的组分比例、加水量、固/液比例和萃取持续时间，分析了一种天然深共晶溶剂在油橄榄（A. oleracea）代谢物萃取中的应用。采用简单的加热方法合成了 NADES，并通过傅立叶变换红外光谱（FTIR）验证了 NADES 的合成。就总多酚含量（TPC）和类黄酮含量（TFC）而言，NADES 中甜菜碱/丙二醇的比例为 1:3，S/L = 1:5，产生的效率最高。在超声辅助萃取条件下，加水量为 40%，萃取温度为 25 °C，接触时间为 60 分钟，TPC 的值为 8.37 mg GAE/mL。在超声辅助萃取条件下，加水量为 0%，萃取温度为 25 °C，接触时间为 60 分钟，TFC 的最佳结果为 14.50 mg QE/mL。
