Abstract
The anti-inflammatory, antioxidant, antimicrobial and cytotoxic activities of the hexane (HE), chloroform (CE) and methanol (ME) extracts obtained from the bark of Prunus tucumanensis Lillo were investigated. Both ME and CE extracts displayed a significant in vitro anti-inflammatory activity similar to dexamethasone and to a commercial formulation (Pygeum) used for the treatment of benign prostatic hyperplasia (BPH). ME exhibited powerful antioxidant (67.6% relative to BHT) and free radical scavenging (RC50 = 5 ppm) activities, antimicrobial activities against Staphylococcus aureus and Mycobacterium smegmatis and did not show any cytotoxic effect on human-derived macrophage cells. Chemical analyses showed that (2 R,3 R)-3,5,7,3',5'-pentahydroxyflavan, β-sitosterol and β-sitosterol-3-O-β-D-glucopyranoside (daucosterol) are relevant components of ME.

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 it
