Separation of Hydrophilic Licorice Flavonoid by Solvent Extraction Method
Bibliographic record
Abstract
Using the mixture of trialkylphosphine oxide(TRPO) and petroleum ether as extractive organic phase,the extraction of hydrophilic flavonoid from the aqueous leaching solution of licorice was carried out.Orthogonal tests showed that the concentration of TRPO was the most remarkable factor for extracting hydrophilic flavonoid,then the phase ratio and the smallest was pH value.It was also found that the extraction rate of total flavonoid(TF) decreased with increasing pH value in the range from 5 to 8.The extraction rate of glycyrrhizic acid rapidly decreased with increasing pH value in the range from 5 to 6,and it almost approached zero above pH 6.The extraction rate of TF rapidly increased with the increase of the concentration of TRPO and decreased with the increase of phase volume ratio(A/O).It decreased with the increase of the system temperature,and the reaction of the extracting TF was exothermic.The ratio of TRPO to solute in extractive complex was 3.The separation between hydrophilic licorice flavonoids and glycyrrhizic acid in the aqueous leaching solution could be achieved by solvent extraction method.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
