Abstract
This first phytochemical study of leaves of Ocotea caudata led to the isolation of ten isoquinoline alkaloids, one of them previously unreported, S-(+)-9-O-demethylnorpreocoteine (1), three known flavonoids, two phenols, two eudesmane type sesquiterpenoids, one proline derivative, one fatty alcohol and a phytosterol. Their structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic analyses including HSQC, HMBC, 1H–1H COSY, NOESY, as well as HRESIMS data in addition to comparison with reports in the literature.

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
