Abstract

fetched live from OpenAlex

Abstract Polyphenols have been recognized as one of the largest and most widespread groups of plant secondary metabolites with marked antioxidant properties as well as recently recognized specific biological properties associated with prevention of chronic diseases such as cardiovascular disease, various cancers and type II diabetes. Within plant kingdom, over 50,000 of structurally diverse polyphenols are present, and their characterization stands as a challenge. In recent years, renewed interest in extraction, isolation and identification of polyphenols especially flavonoids from plant sources have become the core research in food chemistry, pharmacognosy and modern medicinal biochemistry. The NMR spectroscopy, which provides a rapid and nondestructive method for profiling of polyphenols by identification of the characteristic structural features through structural assignments, has been addressed in this chapter.

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.
