Extraction and Recovery of Flavonoids from Tartary Buckwheat Using Deep Eutectic Solvents.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In recent years, the green extraction of natural active ingredients has generated widespread attention. And deep eutectic solvents have widely replaced traditional organic solvents. In this study, choline chloride/glycolic acid (1:2) was chosen as the optimal extractant to extract flavonoids from Tartary buckwheat. The optimal extraction conditions were as follows: water content of 30%, liquid-solid ratio of 40 mL/g, extraction temperature of 60 °C and extraction time of 40 min. And the extraction efficiency reached 27.22 ± 0.31 mg/g. Then kinetic and thermodynamic mechanisms were investigated comprehensively, and the results showed that the extraction process could be well fitted by Fick's second law. In addition, macroporous resins were used to recover flavonoids from extracts. The adsorption efficiency of flavonoids on HP20 resins under the optimal conditions (time of 2 h, liquid-resin ratio of 2.5 mL/g, temperature of 25 °C) could reach 80.14 ± 0.33%.
