Antioxidant Activity Of Centella asiatica Leaves By DPPH Radical Scavenging Method
Bibliographic record
Abstract
The DPPH (1, 1diphenyl-2-picryl hydrazyl) radical scavenging technique was used in this work to measure the antioxidant activity of several Centella asiatica ethanolic leaves extracts. Plant species that shown that, when compared to the reference standard ascorbic acid, an alcoholic (prepared in 70% ethanolic solution) extract of the plant's leaves at higher concentrations had more antioxidant capacity. They showed significant DPPH radical scavenging antioxidant activity. Ascorbic acid and alcoholic leaves extract were found to have absorbances for reducing power of 0.0350 and 0.0580, respectively. Because flavonoids and phenols are present, ethanol extract may have the greatest antioxidant action

How this classification was reachedexpand
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.
