Acetylcholinesterase and monoamine oxidase inhibitory activities of <i>Pistacia falcata</i> Becc. ex Martelli extract
Bibliographic record
Abstract
Plants in the genus Pistacia represent valuable natural resources for neuroprotective research based on ethnomedicinal knowledge. While other Pistacia species have been extensively studied, Pistacia falcata (P. falcata) has received limited attention. This study aimed to characterise the phenolic compounds in P. falcata extract using HPLC-DAD-MS/MS and evaluate its neuroprotective potential by assessing its ability to inhibit important central nervous system (CNS) enzymes—acetylcholinesterase (AChE) and monoamine oxidases (MAO-A and MAO-B). P. falcata displayed a rich profile of phenolic acids and unique glucuronidated flavonoids, contributing to its potent antioxidant activity (IC50 23.37 ± 0.63 µg/mL). The extract exhibited a stronger inhibitory effect on MAO-B than MAO-A and inhibited AChE (IC50 0.22 ± 0.01 mg/mL). These findings suggest that P. falcata has significant neuroprotective potential, warranting further investigation as a source of functional food and nutraceutical ingredients for managing neurodegenerative diseases.

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.
