Comparative Study of Antioxidant Activity of Flower of Aloe vera and Leaf Extract of Aloe ferox
Bibliographic record
Abstract
Great attention has been focused on medicinal plants and phytoconstituents due to their free radicals scavenging tendency. The present study investigates the comparative antioxidant ability of aqueous extracts of flower of Aloe vera and leaf of Aloe ferox. Antioxidant activity was assessed by using the DPPH, FRAP and ABTS+ free-radical method. The IC50 values of aqueous extracts of flower of the A. vera and leaf of A. ferox in DPPH assay were 406.04 and 517.01 µg/ml, in ABTS+ radical scavenging assay were 44.72 and 173.05 µg/ml, EC1 in FRAP assay were 0.28 and 0.51 (mg/ml) respectively. Results of the present study showed that antioxidant capacity of whole leaf of Aloe ferox Mill was significantly higher than Aloe vera flowers.

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.
