Abstract
BACKGROUND: Teucrium hyrcanicum belonging to the Lamiaceae family is a native plant in Iran; it is called Maryam nokhodi-e-jangali in Farsi. OBJECTIVE: The aim of this study is to evaluate acetylcholinesterase inhibition (AChEI), antioxidant activity and flavonoids content of T. hyrcanicum methanol extract. MATERIALS AND METHODS: The air-dried and the ground aerial parts of T. hyrcanicum were extracted by percolation method with methanol. Antioxidant activity of the extract was investigated by using 2,2'-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power assay (FRAP) methods. In addition, AChEI and flavonoid content of T. hyrcanicum methanol extract were measured. RESULTS: The results showed that total flavonoid content of T. hyrcanicum in reference to the standard curve for quercetin was 20.70 ± 0.05 mg quercetin equivalents/g of extract. In the FRAP method, the antioxidant activity of T. hyrcanicum extract and butyl hydroxyanisole (BHA) (as a positive control) were 657.5 ± 0.04 and 880 ± 0.06 mmol Fe II/1 g dried extract. According to results of DPPH assay, half maximal inhibitory concentration (IC50) value for DPPH radical-scavenging activities of T. hyrcanicum methanol extract, vitamin E and BHA were 74.6, 14.12 and 7.8 μg/mL, respectively. IC50 value for AChEI of T. hyrcanicum and donepezil as a positive control were 2.12 mg/mL and 0.013 mg/mL. CONCLUSION: The results of the present study showed T. hyrcanicum is a natural antioxidant that the flavonoid content can be responsible for extract effects.

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
