How Medicinal is Dried Angelica archangelica Relative to the Fresh Plant?
Bibliographic record
Abstract
The chemical composition of natural products is responsible for their medicinal properties. Angelica archangelica is known for its antimicrobial properties, which stem from terpenes that make up the bulk of the extract of the fresh plant. The dried root can be purchased from commercial sources and is sold for the above-mentioned medicinal characteristics. Though thorough identifications of the fresh plant’s composition have been made, there has been little in the way of characterization of the chemical components of the dried root. In this study, we use both organic solvents and supercritical CO2 to extract the dried root and compare the results to the essential oil (made from the fresh plant). The results show that the dried roots used in this study were devoid of the terpenes linked to the plant’s medicinal properties, and rather contain osthole, a coumarin derivative found in relatively small abundance with respect to the plant’s terpenes.

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.
