LC-MS AND ESI-MS QTOF-MS ANALYSIS OF GLYCEROPHOSPHOLIPID AND TRIACYLGLYCEROL SPECIES IN DEVELOPING WILD ARTICHOKE ACHENES
Bibliographic record
Abstract
The present study, aimed at presenting comprehensive data on the content of storage and structure lipids of the unexploited wild Onopordum acanthium vegetable oil during achenes development.By using ESI-MS, and Total mass spectral intensities, we identified and determined the proportions of sixteen TAG species.POP, SOP, OLS, GLL, ALO and PLLn were detected for the first time.In addition five phospholipid (PL) classes were discerned.Interestingly, each stage of maturation was characterized by the dominance of one or two phospholipid classes with generally Phosphatidylglycerol as the prominent form in all collection dates (48.2% of total PLs).Various PL molecular species were detected in each class of glycerophospholipid.The main acyl chains were found to be palmitic; linoleic and linolenic acids.Unexpectedly, linolenic acid was found more frequently in phospholipids than in triglycerides.Our findings provide useful information about a new source of vegetable oil that can be exploited in food or non-food applications.

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.
