Evaluation of the Biological Activities of Crude Extracts from Patagonian<i>Prosopis</i>Seeds and Some of Their Active Principles
Bibliographic record
Abstract
Extracts of different polarities from three species and three varieties of the genera Prosopis: P. alpataco, P. denudans var. denudans, P. denudans var. patagonica, and P. denudans var. stenocarpa, were screened in order to evaluate their antibacterial, antifungal, anti-feedant, antihelminthic, molluscicidal and toxic activities. The extractions of the plant materials were carried out successively with petroleum ether, dichloromethane, ethyl acetate, methanol and water. All petroleum ether extracts showed antibacterial activity. The dichloromethane extract of P. alpataco showed antibacterial and antifungal activities. Methanol and aqueous extracts of P. denudans var. denudans and P. denudans var. patagonica showed antifungal activities and a slight response to the toxicity test. Fatty acids and a group of pentacyclic triterpenes were identified as responsible for antibacterial activities in some of the active extracts.

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.
