Study on the Extraction and Anti-oxidation Activity of Tannic Acid from Nuclear Shell of Cerasus humilis
Bibliographic record
Abstract
In order to select the best technology parameter for extracting tannic acid,the nuclear shell of Cerasus humilis was treated as the experimental material.L9(34) orthogonal experimental was designed to study the effects of liquid-solid ratio,solvent concentration,extracting time and the extracting temperature on the extraction of the tannic acid from the nuclear shell of Cerasus humilis with alcohol and acetone,respectively.The better extracting conditions of different extracting agents were compared by random experiment;the DPPH was used to study its scavenging effects on hydroxyl radical.The results showed that the best treatment combinations in extracting tannic acid from the nuclear shell of Cerasus humilis was 70% acetone,the extracting time was 5 hours,the extracting temperature was 60 ℃ and the liquid-solid ratio was 1 ∶ 12.The extraction yield was 0.180%.The scavenging activity on hydroxyl radical of tannic acid was 85% with the concentration of 0.1 mg / mL and the IC 50 was 0.023 mg / mL.Tannic acid from the nuclear shell of Cerasus humilis has high anti-oxidative activity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
