(L.) is a valuable source of nutrients. Nutrients have adaptogenic, immunostimulating, nootropic, anti-inflammatory and anti-cancer properties. Natural deep eutectic solvents (NADES) consisting of choline chloride and malonic, malic, tartaric or citric acids have been first used to extract biologically active substances from . The total content of polyphenols has been determined by the Folin-Ciocalteu method for all extracts. Antioxidant activity has been determined by the phosphomolybdate method, and antiradical activity has been determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Rosavin concentration has been determined by high-performance liquid chromatography (HPLC). Extraction kinetics has been evaluated regarding the effectiveness of NADES with each other and with reference solvents (water and 50% ethanol) has been made. Extraction conditions have been optimized according to the Box-Behnken design of the experiment. The optimal parameters of the extraction process have been established. The antibacterial activity of NADES-based extracts against bacterial cultures of , , and has been studied.
（L.）是一种有价值的营养来源。营养素有适应原、免疫刺激、益智、抗炎和抗癌特性。由氯化胆碱和丙二酸、苹果酸、酒石酸或柠檬酸组成的天然深共晶溶剂（NADES）首次被用于从 中提取具有生物活性的物质。所有提取物的多酚总含量均采用 Folin-Ciocalteu 法测定。抗氧化活性采用磷钼酸盐法测定，自由基清除活性采用 2,2-二苯基-1-苦肼基（DPPH）法测定。采用高效液相色谱法（HPLC）测定罗莎文浓度。评估了 NADES 之间以及与参考溶剂（水和 50%乙醇）的提取效率，并根据实验的 Box-Behnken 设计进行了优化。确定了提取工艺的最佳参数。研究了基于 NADES 的提取物对 、 、 和 的细菌培养物的抗菌活性。
