Abstract

fetched live from OpenAlex

Both the fruits and stems of Heracleum maximum Bartram, a common Apiaceae found throughout northern North America, have been traditionally consumed as spice and food by American First Nations and settlers. As both parts of the plant bear a distinctive scent, they have been submitted to volatile constituent extraction and their essential oils were studied by GC–FID and GC–MS. The fruits’ oil was found to be mostly constituted of aliphatic esters, with octyl acetate (65.6%) as main constituent, while the stems yielded a generally terpenic oil, dominated by limonene (45.2%). These results were in line with data for other Heracleum species, and constitute the first study of the volatile constituents of H. maximum. The observation of several octadecenyl acetates as trace compounds in the stems’ oil allowed for the comprehensive identification of these uncommon and closely related isomers.

Full frame distilled prediction

Teacher imitation

Not 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.
