“…This is a reasonable result since the viscosity and density of the applied DESs are high, thus causing slow mass transfer [6]. According to the data available in the literature, viscosities and/or densities for the investigated DESs are as follows: ChCl : fructose [12]. Addition of 25% and 50% of water significantly improved rutin extraction in all experiments, which could be attributed to the decrease in the viscosity of the DESs by addition of water, as described by Duan et al [6] and Zhao et al [11].…”

“…The same extractions were also performed with ultrapure water, yielding 0.734, 0.783 and 0.706 g of rutin from 100 g of plant for 1, 3 and 6 h. We did not expect higher yields in the water extracts, due to the low solubility of rutin in water, as described by Huang et al [12]. Differences in the extraction efficiencies among the DESs studied can be explained by structural differences as reported by Zhao et al [11].…”

Extraction of rutin from Ruta graveolens L. leaves was performed in choline chloride based deep eutectic solvents (DESs). Firstly, rutin extraction was performed in five different DESs; pure DESs and with different amounts of water added (25% and 50% v/v), for different times (1 h, 3 h and 6 h) in order to find the best DES for further optimization. Choline chloride plus citric acid (1 : 1) was shown to be best DES and optimization of rutin extraction was performed using response surface methodology (RSM) based on the selected solvent and applying different extraction parameters: extraction time, temperature and water content.The rutin content was determined by HPLC and varied from 0.55 g/100 g of plant to 1.81 g/100 g of plant depending on the applied conditions. The best conditions for rutin extraction were found to be: a temperature of 70°C, an extraction time of 52 min and a water content of 27 % for the extraction of 1.88 g /100 g plant.

“…NADES therefore have good potential for the extraction of valuable secondary metabolites for use in the food and pharmaceutical industries. Recently, NADES have been applied for extraction of flavonoids (Wei et al 2015a;Radošević et al 2016;Bakirtzi et al 2016;Dai et al 2016), alkaloids, phenolic acids, anthraquinones, saponins (Duan et al 2016, phenolic compounds (Wei et al 2015b), xanthonoids (Mulia et al 2015), rutin (Huang et al 2017), flavonoid glycosides, and aglycones (Zhuang et al 2017) from plant materials. The mentioned publications describe the extraction of flavonoids other than those described in our research and the application of different NADES solvents for sample preparation.…”

Natural deep eutectic solvents (NADES) are promising green solvents for the extraction of compounds from natural products. This is the first study to use a sample preparation method based on NADES for the extraction of flavonoids (rutin, hesperidin, neohesperidin, naringenin, naringin, quercetin, hesperetin, and chrysin) from fruits, vegetables, and spices. In total, 17 types of NADES based on choline chloride, acetylcholine chloride, choline tartrate, betaine, and carnitine with different compositions were tailored to test their extraction efficiency. Operational conditions such as water content in NADES and liquid/solid ratios were also studied. A response surface methodology was used for multivariate optimization of some extraction parameters. Efficient recovery of extracted flavonoids (higher than 70%) was achieved using a 30% water solution of acetylcholine chloride/lactic acid ratio (2:1) as an extraction solvent. Other conditions for SLE-NADES were as follows: liquid/solid ratio 3:1, extraction temperature 60°C, extraction time 30 min, and stirring speed 1400 rpm. Each extract was analyzed by UHPLC with UVand MS/ MS detection. The developed method was applied for analysis of flavonoids in fruits (cranberry, fruits of Lycium barbarum L., grape, plum, and orange peel), vegetables (onion and broccoli), and spices (mustard, rosemary, and black pepper).

“…Thus, DESs possess the same favourable properties as ILs, including negligible volatility at room temperature, wide liquid range, tunable viscosity, superior thermal stability and designable structures . Additionally, DESs are considered superior to ILs for the properties of biodegradability, environmental friendliness and lower costs for preparation, and have been used in various chemistry fields, including catalysis, organic chemistry, electrochemistry, analytical chemistry, and extraction processes of chemical compounds …”

Introduction The Epimedium herb, Yinyanghuo in Chinese, is a famous Chinese herbal medicine. In this study, an efficient extraction method was developed for the extraction of major bioactive constituent epimedin A, epimedin B, epimedin C and icariin from E. pubescens Maxim. using deep eutectic solvents (DESs). Methodology A series of choline chloride‐based DESs were synthesised for the extraction of four target compounds. DES composed of lactic acid and choline chloride with the ratio of 2:1 was selected as the most promising. Three vital factors affecting the extraction yields including water content, volume of DES aqueous solution and extraction time were optimised systematically by Box–Behnken experimental design in combination with response surface methodology. A high‐performance liquid chromatography ultraviolet (HPLC‐UV) method was developed for the sensitive and accurate quantification. Results The optimal extraction conditions were obtained as follows: water content of 17.5% (v/v), volume of DES aqueous solution 3.14 ml, and extraction time of 21 min. Under the optimal extraction conditions, the developed DES method could supply almost the same extraction yield as 50% ethanol, which were 98%, 99%, 97%, 96% for epimedin A, epimedin B, epimedin C and icariin, respectively. Conclusion The present study exhibited high efficiency in extraction of prenylflavonol glycosides in E. pubescens Maxim. Thus, DESs could be used as an alternative for efficient extraction and quantification of biologically active components from natural medical plants.
